Take heart! Uma was saved by the two of you because of how much you didn't know. Now, because of how much you do know, Uma will be better than the day she left Pearson all those years ago.
@@NibsNiven nah, they bought a complete wreck for very little money, and did not repair the bad knees yet it still held together. They got a bum survey apparently but Prehaps forgot that the surveyor knew the value of the boat and sadly that influences the survey , a condition survey takes into account the boat value. Any 30 year old boat worth $5k will have all sorts of issues but is worth $5k….(or what ever pittance they paid).
When you are finally done with your massive sailing adventure, you would both make a great business team giving advice to other inexperienced yachties, like you once were, as you have come such a long way since when you first bought the boat. “Good things come to those who wait”!
In a way, they already are giving advice to inexperienced yachters. Anyone who is becoming inspired by them, are gaining even more insight with this latest refit.
They would be a great team at any business endeavor. Their energy and ability to learn and apply so many different things is incredible. Sail on Uma, Sail on...
So great to hear the good news. You were my original sailing channel. I am so glad the same boat will be around because it gives hope to all of us trying to sail on a shoestring.
When I first saw the word Ultrasound, I thought you might be pregnant which is wonderful in itself. But also, many people raise their children on boats, so was confused. But now all is well again. Smiles. Good luck and I am looking forward to watching your rebuild of Uma as well as your rebuild of the 4x4 and your land adventures too. :)
Dan, when you reglass the bulkheads to the floor, be sure to double check with your guy about the bulkheads being glassed hard against the hull. Usually builders leave that gap so the hull can flex and not create hard spots where the hull can be damaged. No different that installing stringers in a boat. Keep up the great work and glad the news was good on the ultrasound.
Great episode, but you built it up for a mini Kika announcement and let us down, I'm happy Uma is good to continue, but a little sad no mini Kika soon, oh well.
Back in the 70’s Ericsson built a 30’ boat that spent its sailing time in the heavy winds of San Francisco. The boat oil canned, and the yard said it could not be completely repaired. Ericson redesigned its entire boat line, adding a fiberglass frame grid which was epoxied and laminated into the hull before the enterior was fabricated which was intern bonded to the grid and hull. The 30’ boat was bought back by the company and scrapped.
Think of how enormously helpful this is for other sailors and boats sitting in junkyards that can return to the water. Recycle, renovate, repair the boats we have. Clean up the Earth! It is the right thing to do! What a great learning experience for boat architects, builders, boat owners, and the environment. I have been watching Sailing Uma for many years. You are two normal, appealing, smart, interesting people.
There was a comment about Deming, and data. One important piece of info is the distance Uma has already gone in your hands. Another is all the repairs you have documented. You would be adding strength and safety to that starting point. Not going with a new old boat of unknown strength. This US was a prudent check, and probably not that costly to do. Good luck going forward.
PUT THE CHAIN PLATES ON THE OUTSIDE. I did that on my 65' Pearson (33") and it has been great! No deck leaks and where the knees are now is super thick. Hope all is well
I hadn´t followed your adventure for a while. When i saw your decomposed boat, i thought you better had sold it while it was still a sailing boat... I guess that surveyor, for the first time in his career, was able to check a boat completely. But the obvious points of concern still are the construction of the attachement of the keel and the mast puttings.... Good luck, keep faith.
Over the last decade you resurrected a basket case and created a truly unique and beautiful adventure vehicle. This latest prognosis has addressed the viability for a second reconstruction. Many thanks as always for sharing the details ⛵️
Ultrasonic non-destructive inspection (UT NDI) uses sound waves to measure thickness of a composite laminate and search for inclusions or delaminations within that laminate. The rate of travel of the sound wave depends on the density of the material. When the sound wave hits a change of density in the laminate or bounces off the back side of the part it creates reflections that are picked up by the technician's instruments. Delaminations, blisters, or inclusions (embedded material that is not fiberglass) show up as a short return signal with respect to the pristine areas that indicates where the delamination is and the depth of it within the hull. The inspection process proceeds by finding areas of good material than using the signals measured by the tool to find areas that have problems. As mentioned in the video a couplant is used to ensure the sound is transmitted into the part to get good readings. Really sophisticated UT NDI systems used by some Aerospace companies that make composite parts for aircraft can use lasers to create the sound pulse on the composite and then measure the response within the part. A great video update and good news for Uma. Thanks for sharing. Cheers!
That was a hek of a click bait! "ULTRASOUND" drives your mind TOTALLY elswhere! And you know it! Love you guys! Hope the next ultrasound will be the one we all waited to hear from you. That is, if it's also your wish...
Been following for years, so was on the edge of my seat for the results of this test. So happy for the good news! At 16:16 Dan sail “mil” when I think you meant “millimeters”. A Mil is one thousandth of an inch, or about 40 times smaller than an inch. As a former machinist, I notice the misused term frequently and it always drives me nuts.
Now don't tell me everyone hasn't skipped from 5:17 to 15:05 to hear the outcome of the scan, there's no way I could wait!! Great news congratulations on the new baby😄
The very reason I dislike inboard chain plates , that is the very reason I'm firm believer on external chain plates. Glad to see she came out usable. Looking forward to your next clip. Best to you both . Angus. SV Violet Walters
I am so glad this was not a video that progressed along the lines of, "Our boat is too far gone (queue the crocodile tears). So, we are going to buy a new boat." Looking forward to watching you build out a configuration that will work well for you. Cheers.
Wow! This makes me feel even better about you refitting her because now you/we know she will be safe and sound for you two to keep journeying. What peace of mind for both of you to know that she is safe, and then to have the help to make sure you do it right this time. Not that you did it wrong last time, but you had a lot less experience, and back then you didn't realize that the manufacturer didn't actually properly attach the supports of the boat.
Good news I guess. Now you have to balance the cost of a rebuild, knowing that when you are finished you will still have a boat of a known vintage.. A fine balancing act...good luck.
Hi Dan and Kika I have worked at sea for 28 years and today I still remember all the ships I have worked on to date. I have always created a loving relationship with all the ships I have been on and it will be like that until the day I retire. That's why I completely understand how you feel about UMA She will always be your baby, enjoy it and keep going because it's worth it. All the best to you, cheers
I think you could find a solid hull in almost anywhere and rebuild a boat from there. When I saw your earlier videos, I questioned whether the effort you were putting in rehabbing the structure was worth it. Maybe all future surveys should be conducted with an ultrasound machine rather than a hammer.
The best news for UMA ! She now knows not only that you love her and do the best for her but that you have brought 'aboard' the best team to help you make her healthy and beautiful beyond her wildest expectations. SO happy for you both. I know that you have never been afraid of hard work or learning more things to carry forward. You must be elated. Onward with all of us cheering you all the way. 👏👏👏👏👏💖💖💖💖💖❣
I worked at Boston Whaler they put different color fiberglass chop when spraying the mold so many per sq. inch then move the gun. Does your hull show any color strands per in. Then pop the mold and tap every Sq. inch with a neoprene tip hammer to find any voids in the gel coat. And we through you guys were having a baby...
Ultrasound! And here I was expecting news of a new little sailor with big hair on the way! As I've mentioned in previous posts, if she were my project I wouldn't think of putting more single layer fiberglass directly onto the old micro fractured hull as your ultrasound tester is recommending. 1- Remove the remaining interior completely, including the chainplate knees. (You do have a Sawzall?) 2- De-grease the entire surface and then grind to raw fiberglass. 3- Scrub it again with MEK or similar powerful de-greasing agent 4- Treating the existing hull as an outer skin, which is all it really has the strength for, vacuum infuse a new core and inner laminate in place over the entire hull. 5- If it were my choice I would use epoxy resin and balsa core. Once the balsa has every void between the blocks filled with epoxy during infusion it will never rot and the bond to the old hull will be stronger than if you use foam. 6- You will now have a new hull with some insulation, far stiffer than any single skin patch job onto the existing hull. 7- Now build a full length stringer at the turn of the bilge and use a tie rod to carry the rig loads down to it and partial ring frames connected to the keel floors. 8- Reinforce the rudder post regardless of whether it "needs" it or not. The infusion process is so time effective (2 hours per side) you will have less time involved than any attempt to patch the existing hull by hand layup.
Glad that you sought out professional help on the soundness of the hull to ensure your safety when further exploring our world. I because of my age would have bought a newer boat, but understand your reluctance to get rid of UMA after all of the time and years spent to make her a seaworthy boat and take you on all of your travels over the past 9 or 10 years. I know I have binge watched your videos after I found your channel about 5 years or so ago. Keep the videos coming and I will watch as you put UMA back together better than she has been in many, many years since she was initially built.
You guys are getting a master class in boat building and refurbishment with this inspection you now know the areas you must expend your efforts on and how it has to be done.
when I saw "ultrasound" in the title, my first thought was that there was going to be a new little Dan and Kika running around on the boat. LOL Glad to see that the boat will live on and be even better than ever.
Been following since you started and put a forklift motor in the boat.( I thought you were crazy) Ya know...a time comes when you have to put the pet down and move on to bigger and better and different things after a period of mourning. UMA has had an amazing second life.
That inspector probably thinks you're crazy for sailing that little day cruiser as a blue water boat and for putting that much effort into Uma. Unlike with humans, where all we care about is extending or prolonging life, without regard to QUALITY of life, you guys are extending that boat's life and improving it while building the boat you want. I'm glad little Uma was deemed safe overall and repairable.
This video taught me a lot. I've had my boat (fiberglass built in 1976) for soon 30 yrs now but a couple of yrs ago it fell over at the yard during a winter storm (through my membership I was a part owner and it turned out I couldn't sue as bad ground was part of the reason). Well, the boat is in nearly the same stage as Uma: gutted and in need for interior re-lamination and repair of the bulkheads/through-holes. What caught my attention in the video was the delamination of the knees. I will check and possibly make "new" ones. Thx Dan and Kika.
Now the fun begins, you get to put your education to work, as the hull will have to be supported on the inside, to close to original shape/dimension, while tabbing in new structure. Best wishes from Northern Canada.
For a TD5 land rover, keep a spare injector loom (oil gets forced down the wires and ends up in the red plug to the ECU). Also keep spare injector seals and make a tool out of a set of grips to remove the injectors. Those are two things that are well worth keeping in stock. Might save you one day.
Sorry it cost you some time and fear, but to help so many with your struggles and set backs is why this channel is such high standards and real. Another great show as always, been watching this adventure for a few years, was painful to think UMA was going to be retired possibly to old boat home was a bit scary. May you both have good health, smooth waters and wind in your sails ahead!
Glad to hear the verdict! Say, you could have some of your viewers translate what the surveyor said on video and add closed captions to those parts... I don't speak Italian but I'm making an assumption here that was motioning at the part of the keel structure where it transforms from the really strong and strengthened, thick lamination of the keel to the thinner hull around it. I suppose he didn't go so far as to prescribe a laminate schedule (a list of the sequential layers to be used) [Edit: just came to the part where you say he will be helping with that, excellent!] but now that it is known that the work is worth it, that transitional region and the knees can have an additional layup planned for them! Aiming at a smoothly transitioning laminate thickness from the immovable object that is the keel to the progressively thinner parts of the skin of the hull. That way the forces which the glass fibers do transmit don't concentrate on an all-of-a-sudden less robust section, but have the time and space to dissipate over a larger area of structure. I wouldn't have even thought about the mast sitting there but in hindsight it does still weigh something.
It wouldn’t have been the end of the channel. As we always have more adventures lurking. But yea we were really nervous that is would be the end of our beloved Uma.
Ultrasound is for kids, x-ray the whole thing is the king way to go. I mean seriously, have border patrol do it, sometimes they are willing to do this with mobile x-ray for semi trucks, they need training on unusual things as well. I was a truck driver and had conversations with border patrol and most unusual thing to scan was a sail boat on the trailer, they can layer the scan to see items based on light resistance. Some of the x-rays now do 3d models of the items.
Beautiful illustration of how Ignorance is Bliss, but now, that you are evolved, invested and more knowledgeable, you will move forward in a much more coherent manner. This development can be seen in many walks of life, whether talking about boat ownership, taking on big challenges or completing big adventures. Same lessons can be applied to relationships, establishing or growing a business, or any major project (e.g. Home Renovation) that you care to parallel this example to. Kudos for the effort and smarts to get through the tough times and now progress with knowledge and awareness. Too many sailing channels focus on the fluff, and incidentals that come after the selection of a correct platform choice. Uma is the right size to live aboard, cross oceans and sustain a lifestyle above monastic existence...... Other boats are too large and become a money pit, others too small and the capacity to journey and live sustainably ultimately falters. Fascinated to see the rebirth from here - especially when you consider how many old boats can be had today, which remain passion projects for so many, but ultimately have few good bones to build upon........ Fair winds, and good luck.
What wonderful news that Uma's bones are good; she just needs some rehab! So much has happened in your lives and adventures in the over a year (!) since I watched one of your videos. Off to catch up from your archives. Have missed your vids in my life! Glad you're well. Cheers!
Thank you for this. Bolted on keels get a good deal of media coverage, but encapsulated keels don’t. Ultra sound testing is used on cast engine blocks, crane booms, and I believe steam or boiler lines as nondestructive testing. Use on fiberglass is another good engineering application. Now you have a scientific tool available to inform your actions. Thanks again and take care.
Honestly. Part of me wanted to see a new Uma Boat. Pearson should have recalled this too! But I'm excited to see what your creative Architectural Minds will design for Uma 2.0. Then she can go into a boat museum in her retirement rather than a scrap yard now. Many Blessings!🎉
The ultrasound gel is just a transducer/ conductor for the uktrasound head to send the waves :) that way the wave is not disrupted :) Good luck . The translator didng translate everything he was saying but i assume she gave u a good summary :)
I say we all just pull together and buy them a new one! As much as I want to see her revived, it'd be quite cool to have your followers help with another one!
Again you guys show the most logical of ways to make decisions about important and life changing events. A good lesson for anyone, anywhere. Sounds like you will be moving forward with some solid advice and direction. You would think that Pearson might want to help out a bit since you are such good advertising for their brand? Best of luck getting back to it and some more about the camper van when you get a chance😉
Have you considered moving the chainplates to the outer edge of the hull? Most of the newest plastic boats (Beneteau, et al) have done this. The rigging loads are significantly reduced, the structure of the hull itself is easily reinforced with no bending moments and a 105-110% jib can be trimmed inside the uppers. You all have done such a great job so far, this refit is the biggest but the results will be an excellent boat that you know completely.
Moving away a bit from “ this is all great guys” I am glad you understand the archirectural\structural considerations wrt tapering loads into the structure and avoiding hard points( stress raisers).. Triangulating the keel mast compression and rig pretension together is a great start. Converting those piffly webs into ring frames and adding some foam stringers and uprights to minimise the panel areas would be good too all without impeding on the available accommodation by more than a few mm. best luck, it’s one of bill shaws better designs imo and she sails like a witch . A keeper
There are a couple podcasts that might help you out regarding fiberglass, epoxy, carbon fiber and application. Both will respond to your questions. One is "The Duracell Project" He is a master when it comes to laminating , The other is "Sven Yrvind" and his canoe yawl build. Both are an incredible resource. Hope this helps. You've got a big job ahead but I'm certain not more than you can handle.
Almost undoubtedly the most important aspect of your renovations, knowing how flexible or rigid Uma's hull needs to be, section by section. This is great groundwork and will be rewarded by allowing you to create a really good plan for building the foundations of your redesign. Such a knowledgeable expert is so useful to have in your planning stage. I look forward to seeing the build over the coming months.
Yikes! I swallowed my heart for a minute there, bc I didn't peek at the comments. It's a lot of work ahead but bc of your dedication, Uma is going to be as sturdy 50 years from now as the moment you finish the re-fit. I think she called to you two bc she knew you were the ones to heal her and love her the way she needed. Blessings upon you, lovely ones.
Interesting surveyor, not understanding a word of what he was saying, I understod perfectly the meaning of his message. Looking forward to the rebuild. I know you will do a perfect job!
Amazing, all those glass hulls from the 60s/ 70s that were overbuilt are still sailing the oceans 60 years later. William Crealock was one of those designers. He designed boats for Erickson, Westsail, Pacific Seacraft, Clipper Marine among many others.
Brilliant bit of video direction, to ramp up the tension by having to wait for an interpreter! So glad the baot will be better than ever when you have worked more of your magic.
Great info, if only there was something like this near me. I'm having to make decisions like yours without the possibility to get an ultrasound check (I had no idea this existed).
Go forward with structural foam, vacuum bag to the hull, then structural surface on top. A hull within a hull. Our boat is 1” divynicel resin infused. So light and strong and pretty easy. He will probably give you some other ideas too. Best of sailor’s fortune moving on.
Something we can all learn from hear - always ask questions, always be open to learning more. None of us knows everything. But if we're willing to always be curious maybe we can know enough!
Much as I respect the process, I can't help but feel that this is really nothing more than a band-aid solution. I would seriously consider the amount of $$ you're going to spend, the amount of time and the mental effort and see what that total is compared to a newer or new boat.
So happy that you don't have to "through" Uma away. Once you get the repairs done she should be good for a long time or will be in great shape to sell and get something different.
Great news! Mind you, Dan looked a little 'cheesed off' at the end of the episode. He no doubt knows how much work this is going to entail. Hearts up, guys! We're all behind you!
I am so relieved that Uma will live again! I know that it will be beter than it was when it was new when you guys finish. I am looking forward to the rebuild and the day Ume sails again.
Well THIS was a ride!!! I thought for sure a new life would end Uma's life. THEN I realized what was about to happen and it was worse... dead Uma with NO new life... Glad it worked out. High Stakes!
Have you considered making it a sandwich boat from the outside to the inside? That would give you thermal insulation and a bullet proof structure in one go. Modern cores are really good.
Great news! And interesting, too. Perhaps you will explain this as you progress, but would you explain "... you can definitely make the hull too stiff ...", and it should be flexible in places? That is not intuitive, to me, at least, maybe others. Thanks for sharing this step in your process.
A prime case of ‘ignorance is bliss’! Would you really have crossed the North Atlantic if you had known what you now know? But good on you - you’re still smiling. 0:00

5- If it were my choice I would use epoxy resin and balsa core. Once the balsa has every void between the blocks filled with epoxy during infusion it will never rot and the bond to the old hull will be stronger than if you use foam.
6- You will now have a new hull with some insulation, far stiffer than any single skin patch job onto the existing hull.
7- Now build a full length stringer at the turn of the bilge and use a tie rod to carry the rig loads down to it and partial ring frames connected to the keel floors.
8- Reinforce the rudder post regardless of whether it "needs" it or not.
The infusion process is so time effective (2 hours per side) you will have less time involved than any attempt to patch the existing hull by hand layup.
Whew, that was close. I thought she got you knocked up. 🙂 You smiled, didn't you?
Glad that you sought out professional help on the soundness of the hull to ensure your safety when further exploring our world. I because of my age would have bought a newer boat, but understand your reluctance to get rid of UMA after all of the time and years spent to make her a seaworthy boat and take you on all of your travels over the past 9 or 10 years. I know I have binge watched your videos after I found your channel about 5 years or so ago. Keep the videos coming and I will watch as you put UMA back together better than she has been in many, many years since she was initially built.
Good news, always welcome. 🤗
You guys are getting a master class in boat building and refurbishment with this inspection you now know the areas you must expend your efforts on and how it has to be done.
Good news! Leaves me wondering, what is the other project you mentioned but didnt give more details about?
when I saw "ultrasound" in the title, my first thought was that there was going to be a new little Dan and Kika running around on the boat. LOL Glad to see that the boat will live on and be even better than ever.
Been following since you started and put a forklift motor in the boat.( I thought you were crazy) Ya know...a time comes when you have to put the pet down and move on to bigger and better and different things after a period of mourning. UMA has had an amazing second life.
That inspector probably thinks you're crazy for sailing that little day cruiser as a blue water boat and for putting that much effort into Uma.
Unlike with humans, where all we care about is extending or prolonging life, without regard to QUALITY of life, you guys are extending that boat's life and improving it while building the boat you want.
I'm glad little Uma was deemed safe overall and repairable.
I just recently bought a Natuzzi leather couch and I'm loving it. You should reconsider and put one in your sailing raft.
Some excellent advice here.
This video taught me a lot. I've had my boat (fiberglass built in 1976) for soon 30 yrs now but a couple of yrs ago it fell over at the yard during a winter storm (through my membership I was a part owner and it turned out I couldn't sue as bad ground was part of the reason). Well, the boat is in nearly the same stage as Uma: gutted and in need for interior re-lamination and repair of the bulkheads/through-holes. What caught my attention in the video was the delamination of the knees. I will check and possibly make "new" ones. Thx Dan and Kika.
wow, you had me there for a moment 😅
wow this time i didn't even need any translation😅. happy for the good news of this ultrasound! cheers!
Sad looks are not for the good news but for all the hard work you guys will have to do putting the boat all together the way you want it.😁
Now the fun begins, you get to put your education to work, as the hull will have to be supported on the inside, to close to original shape/dimension, while tabbing in new structure.
Best wishes from Northern Canada.
Outstanding News! Uma will be re-born...Safer and Sronger!
For a TD5 land rover, keep a spare injector loom (oil gets forced down the wires and ends up in the red plug to the ECU). Also keep spare injector seals and make a tool out of a set of grips to remove the injectors. Those are two things that are well worth keeping in stock. Might save you one day.
We have a TD4 😉
@@SailingUma disregard in that case! She's a beauty either way.
Sorry it cost you some time and fear, but to help so many with your struggles and set backs is why this channel is such high standards and real. Another great show as always, been watching this adventure for a few years, was painful to think UMA was going to be retired possibly to old boat home was a bit scary. May you both have good health, smooth waters and wind in your sails ahead!
That was a tense couple of hours, onwards and upwards ⛵️⛵️.
And here I thought to myself... it didn't change the Delos owners too much! Click Bait.. but good !! Great channel guys !!
Good news, hard work to come!
Long life to Uma ! ❤
At least six months of hard work await you!! Good job!
Glad to hear the verdict! Say, you could have some of your viewers translate what the surveyor said on video and add closed captions to those parts... I don't speak Italian but I'm making an assumption here that was motioning at the part of the keel structure where it transforms from the really strong and strengthened, thick lamination of the keel to the thinner hull around it.
I suppose he didn't go so far as to prescribe a laminate schedule (a list of the sequential layers to be used) [Edit: just came to the part where you say he will be helping with that, excellent!] but now that it is known that the work is worth it, that transitional region and the knees can have an additional layup planned for them! Aiming at a smoothly transitioning laminate thickness from the immovable object that is the keel to the progressively thinner parts of the skin of the hull. That way the forces which the glass fibers do transmit don't concentrate on an all-of-a-sudden less robust section, but have the time and space to dissipate over a larger area of structure.
I wouldn't have even thought about the mast sitting there but in hindsight it does still weigh something.
OMG I was so scared this was going to be the end. I have such a sigh of relief!
It wouldn’t have been the end of the channel. As we always have more adventures lurking. But yea we were really nervous that is would be the end of our beloved Uma.
@@SailingUma yes. Understands. Thank you for your reply too.
Ultrasound is for kids, x-ray the whole thing is the king way to go. I mean seriously, have border patrol do it, sometimes they are willing to do this with mobile x-ray for semi trucks, they need training on unusual things as well. I was a truck driver and had conversations with border patrol and most unusual thing to scan was a sail boat on the trailer, they can layer the scan to see items based on light resistance. Some of the x-rays now do 3d models of the items.
Beautiful illustration of how Ignorance is Bliss, but now, that you are evolved, invested and more knowledgeable, you will move forward in a much more coherent manner. This development can be seen in many walks of life, whether talking about boat ownership, taking on big challenges or completing big adventures. Same lessons can be applied to relationships, establishing or growing a business, or any major project (e.g. Home Renovation) that you care to parallel this example to. Kudos for the effort and smarts to get through the tough times and now progress with knowledge and awareness. Too many sailing channels focus on the fluff, and incidentals that come after the selection of a correct platform choice. Uma is the right size to live aboard, cross oceans and sustain a lifestyle above monastic existence...... Other boats are too large and become a money pit, others too small and the capacity to journey and live sustainably ultimately falters. Fascinated to see the rebirth from here - especially when you consider how many old boats can be had today, which remain passion projects for so many, but ultimately have few good bones to build upon........ Fair winds, and good luck.
What wonderful news that Uma's bones are good; she just needs some rehab! So much has happened in your lives and adventures in the over a year (!) since I watched one of your videos. Off to catch up from your archives. Have missed your vids in my life! Glad you're well. Cheers!
Thank you for this. Bolted on keels get a good deal of media coverage, but encapsulated keels don’t. Ultra sound testing is used on cast engine blocks, crane booms, and I believe steam or boiler lines as nondestructive testing. Use on fiberglass is another good engineering application. Now you have a scientific tool available to inform your actions. Thanks again and take care.
phew - that must have been nerve racking, very happy for you that the results were positive
Honestly. Part of me wanted to see a new Uma Boat. Pearson should have recalled this too! But I'm excited to see what your creative Architectural Minds will design for Uma 2.0. Then she can go into a boat museum in her retirement rather than a scrap yard now. Many Blessings!🎉
‘Let The Games Begin”-said somewhere in a movie script. 😂🎉❤❤
The ultrasound gel is just a transducer/ conductor for the uktrasound head to send the waves :) that way the wave is not disrupted :)
Good luck . The translator didng translate everything he was saying but i assume she gave u a good summary :)
Sometimes you can find sailboats on GSA auctions. A year ago the naval academy auctioned of their training sailboats.
I say we all just pull together and buy them a new one! As much as I want to see her revived, it'd be quite cool to have your followers help with another one!
Again you guys show the most logical of ways to make decisions about important and life changing events. A good lesson for anyone, anywhere. Sounds like you will be moving forward with some solid advice and direction. You would think that Pearson might want to help out a bit since you are such good advertising for their brand? Best of luck getting back to it and some more about the camper van when you get a chance😉
Pearson has been out of business since 1991.
Uma is like 40 years old I think . I don't think they would be giving any warranty on a boat that old .
And they went out of business because .......................??
Have you considered moving the chainplates to the outer edge of the hull? Most of the newest plastic boats (Beneteau, et al) have done this. The rigging loads are significantly reduced, the structure of the hull itself is easily reinforced with no bending moments and a 105-110% jib can be trimmed inside the uppers. You all have done such a great job so far, this refit is the biggest but the results will be an excellent boat that you know completely.
yes, you both got me!! I really thought you both were expecting!
Moving away a bit from “ this is all great guys” I am glad you understand the archirectural\structural considerations wrt tapering loads into the structure and avoiding hard points( stress raisers).. Triangulating the keel mast compression and rig pretension together is a great start. Converting those piffly webs into ring frames and adding some foam stringers and uprights to minimise the panel areas would be good too all without impeding on the available accommodation by more than a few mm. best luck, it’s one of bill shaws better designs imo and she sails like a witch . A keeper
There are a couple podcasts that might help you out regarding fiberglass, epoxy, carbon fiber and application. Both will respond to your questions. One is "The Duracell Project" He is a master when it comes to laminating , The other is "Sven Yrvind" and his canoe yawl build. Both are an incredible resource. Hope this helps. You've got a big job ahead but I'm certain not more than you can handle.
I am so happy it was good news. Now on with the rebuild. Exciting. Thank you for sharing. Have a great day and stay safe.🙂🙂
Almost undoubtedly the most important aspect of your renovations, knowing how flexible or rigid Uma's hull needs to be, section by section. This is great groundwork and will be rewarded by allowing you to create a really good plan for building the foundations of your redesign. Such a knowledgeable expert is so useful to have in your planning stage. I look forward to seeing the build over the coming months.
Yikes! I swallowed my heart for a minute there, bc I didn't peek at the comments. It's a lot of work ahead but bc of your dedication, Uma is going to be as sturdy 50 years from now as the moment you finish the re-fit. I think she called to you two bc she knew you were the ones to heal her and love her the way she needed. Blessings upon you, lovely ones.
This info is well worth knowing when buying a boat
Interesting surveyor, not understanding a word of what he was saying, I understod perfectly the meaning of his message. Looking forward to the rebuild. I know you will do a perfect job!
Keep at it!!! It will all be worthwhile.
Phew, from the title of the video, my first thought that was Dan might be expecting a baby!
You should hire Aladino from magic carpet, he loves fixing boats and he is the best.
Amazing, all those glass hulls from the 60s/ 70s that were overbuilt are still sailing the oceans 60 years later. William Crealock was one of those designers. He designed boats for Erickson, Westsail, Pacific Seacraft, Clipper Marine among many others.
Brilliant bit of video direction, to ramp up the tension by having to wait for an interpreter! So glad the baot will be better than ever when you have worked more of your magic.
Great info, if only there was something like this near me. I'm having to make decisions like yours without the possibility to get an ultrasound check (I had no idea this existed).
Go forward with structural foam, vacuum bag to the hull, then structural surface on top. A hull within a hull. Our boat is 1” divynicel resin infused. So light and strong and pretty easy. He will probably give you some other ideas too. Best of sailor’s fortune moving on.
Something we can all learn from hear - always ask questions, always be open to learning more. None of us knows everything. But if we're willing to always be curious maybe we can know enough!
Much as I respect the process, I can't help but feel that this is really nothing more than a band-aid solution. I would seriously consider the amount of $$ you're going to spend, the amount of time and the mental effort and see what that total is compared to a newer or new boat.
So happy that you don't have to "through" Uma away. Once you get the repairs done she should be good for a long time or will be in great shape to sell and get something different.
Great news! Mind you, Dan looked a little 'cheesed off' at the end of the episode. He no doubt knows how much work this is going to entail. Hearts up, guys! We're all behind you!
Glad you have experts helping you out. Here's to happy sailings in the future. Fair winds going your way!
I am so relieved that Uma will live again! I know that it will be beter than it was when it was new when you guys finish. I am looking forward to the rebuild and the day Ume sails again.
A brilliant new diagnostic tool. Thank you for bringing it to the wider audience.
Well THIS was a ride!!! I thought for sure a new life would end Uma's life. THEN I realized what was about to happen and it was worse... dead Uma with NO new life... Glad it worked out. High Stakes!
Great video! We love you guys over @ Sailing Sarpedon
Have you considered making it a sandwich boat from the outside to the inside? That would give you thermal insulation and a bullet proof structure in one go. Modern cores are really good.
Great news! And interesting, too. Perhaps you will explain this as you progress, but would you explain "... you can definitely make the hull too stiff ...", and it should be flexible in places? That is not intuitive, to me, at least, maybe others. Thanks for sharing this step in your process.
You really hooked me in on this one. Congratulations. Uncle Kirk
A prime case of ‘ignorance is bliss’! Would you really have crossed the North Atlantic if you had known what you now know? But good on you - you’re still smiling. 0:00
UMA, as she is will still make a wonderful lake boat or coastal cruiser.
