NICE cutting the interview into the project!
Great editing this week! A podcast type conversation overlapping the working shots. Great work !
It's easy to see that Evan appreciates design challenges. That's the kind of collaborator you want. Someone who loves problem solving.
"They take a bit more time, but they're better. They're stronger" Evan is the perfect design partner for you Matt. Completely gets what you want to achieve. The speed will be in the sailing, not the build. Duracell continues to be my favourite nerd out watch. Banging! As we say over the Atlantic pond in Wales.
Elegant engineering solutions.
That’s great, thanks
Hats off to Evens for coming forth with professional help.
totally
I am enjoying your project very much. My favorite part is your very careful explanations for your designs and how you use CAD to make it very clear. Thanks!
Elegant in it's simplicity. Totally future proof. Enjoyed the conversation with the architect... Great video! Cheers!
This video was cleverly edited in such a way to be informative and entertaining. Well done!
My partner is a newly retired Naval Architect who has spent a whole career in North Sea oil industry on mooring system design and Structural Engineering projects. As a hobby many fibreglass and carbon fibre dinghy projects filled any free time.
Your project is on a mammoth scale but the techniques are very similar. Having Evan as a source of advice is perfect for Duracell. He will keep you right on all the vital aspects of the modification.
got me thinking it would be very interesting to know how much total weight is saved by eliminating the steel in chain plates all up. 25% of 1 ton is a lot. 500 pounds is a big fat momma.
Perhaps consider using a soft-attach block where the strop can be looped through the sheave of the block. With the block you presented, a failed shackle could take down the mast, whereas with a soft-attach block you’d have the strop acting as a failsafe should the block itself fail.
Completely agree here, I was going to make the same comment, the shock loading you get through checkstays is immense on a boat this big in big seas, soft attach block is definitely the way forward or even a large friction ring might be worth considering as it will be a static load most of the time. I use soft shackles wherever I can now but I always have a routine for checking the dyneema after any big stress has been put on them, the addition of a technora chafe cover is also a really good idea as it protects from chafe and UV damage
totally, that block was just an example to show how it works
@@TheDuracellProject you’re way ahead of me then!
Evan is an amazing guy . A competent stand up person, they always have a certain air about them.
I"m a firm believer in a boat design philosophy that says any hole in a boat that can be replaced by not a hole in the boat is great. I think more damage is done to boats by small water intrusions that by catastrophic failures. I think the design your building will last for several lifetimes.
You lucked out with Evan, he's golden.
One of my favourite quotes is from British car designer, Colin Chapman of Lotus fame. "Simplify, then add lightness"
Colin Chapman took things past lightness there were just too many failures with dire consequences. It was unfortunately early days when benchmarks did not exist.
Matt you are an absolute inspiration and a master shipwright. The use of modern materials and techniques is genius ! Carbon hinges, solid fibreglass stanchions just a couple of outstanding ideas. You have incredible talent.
That is a great idea. I am so happy for you. Evan is your guy; everybody needs a guy.
Matt Awesome way to do the new chain stays. Matt add Kevlar sleeves to you Dyneema rigging to keep the rubbing down
Intersting that Evan says stainless steel can fail without warning and therefore chooses carbon fibre, my understanding is that carbon fibre can also fail suddenly, such as happens with racing bicycles. Perhaps the margins, loads and shocks are very different on a boat. It's great to incorporate newer materials taking into account their characteristics. Having sailed racing boat with soft shackles, it was super quiet, particularly when tacking! So, Matt you are really creating a smooth, quiet boat, not just a stonger, less leaky one.
Love the interview over the video, Evan like you both, is a very pleasant guy to listen to an I can imagine you two talking for hours on all things boats.
Matt, did you see Sailing NV, in order to get their Open 60 into Fiji, had to heel it way over in order to reduce the draft? That was due to their keel. Part of the way they did that was to fill their tender full of water and hang it from their boom. They broke the boom. It was carbon fiber. If you're going with an aluminum mast, your boom will probably be that too. So don't even think of their solution. Instead, you might look into finding a way to raise your keel.
we did see that video! We're going to reduce the draft.
Props to Evan for all the time and effort to help out Matt on the project.
Really enjoyed the VLOG. Production quality deserves a mention. Thank you
Nice work.
( though I have to admit wincing when I saw that huge deckhouse spoiling that cute catamaran
I truly enjoy watching boat rebuilds on very different styles of boats. Each offers very different approaches. I love how you work with your naval architect in developing very different solutions to common issues that occur as a result of simple wear and tear. Your level of build professionalism and quality is truly outstanding as you build a safe and reliable vessel for your family.
I've watched several of your episodes with Evan appearing in them, I must say I find the maritime engineering/naval architect very interesting.
Edited: It would be a great idea to have a Q & A with Evan.
Best episode yet!! Great work on the boat work, filming and editing!
17:46 that Sam Holmes moment, though
Love the check stay chain plates, what a great solution! I'm familiar with the firm Evan works for, they truly are the leaders in modern tug design worldwide! I've been in the tug industry sine the late 70's
I like my old solid fiberglass heavy sailboats! You guys keep going with your composite stuff. Don't get me wrong I love watching the work but tried and true is what I will stick with when it comes to my life. The tortoise and the hare!
Just noticed, you guys are nearing the 100K subscriber mark! My how Duracell has grown!
I really enjoy learning new methods. I think this channel does it better than any other.
What a good guy Evan is. Nice to have someone to collaborate on the engineering details. Thanks for the interview.
We definitely don't count as cool but we have been creating Dyneema Chainplates for our 1977 Rival 38. Our loads are tiny compared to yours so our design is simpler. We feel somewhat validated and affirmed :-)
Our original chainplates were a simple bronze eye bolt through the deck with a small stainless backing plate. We have bonded in big FR4 backing plates and then drilled for what we call a "chainplate loop" which is a simple soft shackle (overhand knot type). The knot is below deck onto 10mm neoprene then through the deck. The eye has a low friction ring for the shroud tensioning lashing. We have tested using a crane scale to beyond the breaking strain of the stainless wire we are replacing.
Novel chain plate design. Thanks fir sharing the background, design concept and the finished product.
EVANS reference to weight and steam rollers was a saying by Uffa Fox not Gary mull .
Uffa fox was the designer of the first successful planning sailing dinghy , an international 14 that got banned as too fast so he changed to designing displacement boats that could beat the current at time ( 1930’s) and did. They later unbanned his planning designs.
Copies still popular are the Thistle racing dinghy and others
Cheers Warren
I love the chainplate design!
This is a huge amount because you can make,something leak proof. Yes what is there needs work !
Cheers warren
Chafing and water intrusion has now been officially added.
Chafe guard. And there will be a cap, mentioned briefly in the beginning with the cad picture
Awesome to meet you and hear about your marine background Evan
Oh wow that is a really elegant solution.
Another great segment....really liked the interview with Evan cut into the chain plate project.
Sure is fun seeing construction ideas that are way outside what I know about.
Best wishes, please continue and good luck
Forget Total Boat! Your mom is a total legend.
Fabulous video all round.......I remember being put on runners while racing on a big boat and how scared I was that I'd bring the rig down, this video reminded me of those time haha. Anyhow looks like a fine fine job. As always, sending good energy....Neil 😊☘☘
Very cool crew, space age practicality in progress. Just fantastic.
Too many sailors get their first and only warning that they have pocketed corrosion of their chain plates when they fail. Sometimes this happens on a day sail in light winds when you have plenty of crew members onboard to assist in turning a halyard into a light stay to stabilize the mast so you can limp back to the dock while other times your not so fortunate. Last one I dealt with was on a friends boat and it was the day sail, light wind, plenty of crew scenario. He learned that the prior maintenance he was told of involved just taking the escutcheon plates up and adding more marine silicone and not the recommended complete removal of the chain plate for inspection. Basically every time they serviced them they were just sealing the salt water in the pocket up more airtight so that it never dried up causing the chain plate to corrode in half almost taking down the mast when a puff of wind pulled it free of the deck. Now the chain plates will get pulled every few years and inspected as per the yacht manufacturer's maintenance specification.
If you get a "Deal" on a COVID Boat be sure to get a buyers survey and that inspections for signs of pocketed corrosion are done.
Good that Matt is getting rid of all those opportunities for hidden failure. Now any wear will be more visibly noticeable and easily remediated in minutes by replacing a short length if line rather than potentially a few days of work pulling out and matching up a stainless steel chain plate and then reinstalling and sealing it in along with repairing any other collateral damage. This is a really huge improvement.
Best!
Simple, light and strong. Great design all around
Great design solution to those chainplates!
Really cool to see Evan has worked with Bruce Farr (Bruce is an awsome chap!).
That is a wild solution I didn’t think it was going to look like that when it was done
Even after watching you do fiberglass work for a long time you still amaze me on your ideas and how you do it 👍🏻👍🏻
thanks for the content. Love the boat and the colab..
Awesome work guys!💪
Nice, simple, and well thought out design.
That’s a great idea with only one worry. A pointed collision directly on the chain stay. Odds are so low, I too would have gone in your direction. NICE!
True with any design
Elegant solution. However the exposed dyneema loop running over the edge of the deck is at risk when docking etc. Also, the loose block will need a "keeper" of some kind or it (and its mate on the other side of the boat) will be banging around all the time. I'm sure you also have elegant solutions for these, as usual.
I love that you are doing the things that are a bit more work and maybe a bit more money up front but should last forever and never be a point of failure or a possible leak.
HOLY(Hollie) CHAINPLATES Matt, glad the boat engineer approves. The innovations you do fascinates. Good work and entertaining too
love this modification, love simple solutions, makes you wonder why it was never used before (maybe it is?)
but i wonder many folk will be making this modification to their own boats
I don’t know much about yacht construction but it looks simple and elegant indeed
What a blessing Evan is to the project, really enjoyed listening to your conversation. What an elegant and yet simple in concept solution (never mind the hard work it pays in the end, and you never really remember the miserable jobs once they are finnished). Although I've been involved with some quite indepth structural jobs in glass, this makes me realise how old fashioned the work we did on the finer details was. I guess it was ultimately for the profit and time constraints of the company and to match what was left of the boats we were working on so I can forgive the powers that be for that! Laying up on plastic and crawling into a space to apply made me smile as I remembered jobs gone by, the times I ended up wearing it as the space was so tight or that it folded and stuck before I got into position😂 To take time and get things just right to such a degree without such constraints is a joy to behold. I'm living somewhat vicariously through you guys every Wednesday! Thanks again and look forward to the debrief on the deck drains next week. As ever, God bless you all from essex❤
yep, we call it boat yoga. Thanks for watching, James!
Great episode! Thanks for sharing! More progress! Keep rolling Duracell team! 👍👍
It appears that you have made a hole in the hull that will leak water in quite large quantities. How are you going to seal it?
Thanks for another video. Wasn’t sure what Dyneema was, didn’t realize it was rope.
Blending the Zoom Interview with deconstruction video was a great idea.
Very good info on the design philosophy, loving it and the outcome is top notch 👍😍
Great job, a very nice way to get your chain plates!
Looking good 🎉 I like the out of the box thinking with this project. I feel like many of these ideas will be common place in the future 🎉
Roger. I typed to soon and I was watching you. Awesome job Sir!
This approach of fail-safe, no-maintenance design makes absolute sense wherever it can be applied. Yeah, may cost more up front, but considering the future hassles avoided and the peace of mind gained, seems well worth it.
It wasnt Gary Mull, it was Uffa Fox who said it. I have no problem with your cockpit drain standpipes. I have three such standpipes on the sundeer: very heavy wall PVC pipes completely glassed in. They are bulletproof strong with nothhing to go wrong. They have been in my Sundeer for 30 years without problems. If they should break off somehow then the usual bungs or foam plugs would work.
yep! LOVE Sundeers.
Hi nice work, I just want to hi-light a potential problem with carbon composite chainplates. A Shoining Cat berthed near me was struck by lighting, melting the carbon with stainless fittings and sleeves. Composite rigging looks ok, carbon mast looks ok but inside the bulkheads are deformed where steel is attached. So the problem with this cat was the multiple materials with stainless straps and fittings. I like your methods with all composites.
sweet, thanks
such an elegant solution!!!
I finally got to watch one of my favourite channels. ✌️&❤️ from England 👍
Matt, you had me lost on what the final design would look like then a brilliant solution appears at the end.
Wat a beautiful solution for chainplates 👌
Evan, you are good people. 🥰🥰 Looking forward to the keel build also!!
keep it simple clean and strong
Brilliant work and episode as always, mahalo 🤙
I saw that you relieved the sharp edge of the through holes on the exterior side,. Did you do something similar to the inside surface of those holes too? Nice to see Evan, I'm sure you are happy to have his help and advice. Great video. Thanks👍👍😁
hey Jim. yes, I did. it was more difficult to do in the tight space, but I did my best to make it a very smooth transition all around.
Love the partial tyvek sleeves.
Great solution: elasticy and material standard measure versus hard static metal.
My No1 You Tube Channel this week. Great episode 🎉😮😊
Interesting interview! Great vid!
Love the interview
Phenomenal work 😅
Cutting up that carbon chain plate was a tough decision but it was also a good opportunity to get a crosscut look at your laminations. Failure testing without the failure.
sewing a “sock” like ones for anchor snubbers could potentially lower chafing on the dynema and protect from UV if it becomes a problem. However also nice to easily visually inspect them.
wow, looks great!!!
Awesome work this week. I look forward to see those plates under load one day.
See you at the festival! Hope the T-shirt design this year is a little more artistic and relevant!
Interesting idea to bury the chain-plates, it will make it look better and its well protected. Great update 2x👍 Even is doing a fantastic job keeping Duracell looking beutiful and safe.
very tidy solution to the chainplates 👌
Super slick job
Janneke makes this episode fly, as she does every other! Go Janneke Go! What a couple ❤.
Well - I'm not a boat builder or engineer , but I'll have a lot more confidence in your design change when Inspector La Pas 😻
gives you a thumbs -up passing grade on your work 😸😺🙏
Nothing is maintenance free, especially where there is loads put upon it, and wear and tear.
What about the dyneema rubbing on the outer hull?
We’ll install a chafe guard
I believe it was Uffa Fox who originally said that ‘weight is only useful on a steamroller’
Thanks for the correction!
Great design
nizzzzeee design!!!
They make wainscoting in pvc in 48" x 96" which is 3/16" thick. It would be lighter and a better choice for the marine environment. Have you ever thought of going with faux wood grain painting for things like door panels, etc. It is used in the auto and aircraft environment routinely and is not that hard for the "amateur" to do.
