- **UPDATE**
It should be noted, some viewers with a much better understanding of epoxy chemistry than me brought it to my attention that there is no such thing as a memory of resin or liquefaction. With that said, epoxy will soften but not liquify at high heats. It will also shrink again at temperatures that Prism endured that summer which in some cases may make it "pop away" from the original thing it was holding onto. Just setting the story strait. Thank you to our viewers who kept me in line about this, never want to spread bad information.***
The crew on Prism installs and finishes the huge chainplate project they have been working on for weeks. They take some nights off to enjoy the holiday seasons gatherings with other cruisers before getting Prism back in the water.

Thank you for watching!
Awesome update. Seems that when I hear your intro, I know I'm in for a treat.
Agree with you - it doesn't matter the season, it's always tough not being able to attend a family gathering. Glad to see you had a great Christmas anyway :) Cheers from PEI Canada, Bryan
Love those chain plates. You did a great job .
Ditto.
Sailing around the world is more work than most people think. Reality is a little too real from your videos, but I love em.
That is some of the great drone footage of your area. You have always given us a view of real sailing with knowledge of maintenance of real sailing requires. I am glad t see you back on the water, and with so much prep work to get there I hope to see more great videos.
The sunset drone shot was pretty spectacular. Thanks for another great video.
You guys do such a fabulous job and I very much enjoy living vicariously. Actually awaiting your next video, until then Fairwinds and following seas
Thank you!
what an excellent video ...great photography beautiful scenery alot of critical work with chain plates and a bow spirit rebuild ...that is important and well done.
nice to meet up with such nice people and then have another boat to sail along with I've been to the Sea of Cortez 40 years ago ...such beautiful area. ...waves (from Seattle)
Always fun guys! Ahoy! from Sacramento!
I wish I had known you guys were in Guaymas by Chrisman, we would have dropped by to say hello to you. my wife and I are your followers. we as well spent Christmas and new year working in our boat at Marina San Carlos dry dock. our project is going to take us at least one more year though because we can't stay in San Carlos full time I still have to work a couple of years more before retirement. probably some other time and some other place we'll meet. Buen viento y buena suerte.
Excellent footage!
Beautiful repare job. i love mexico so enjoy your videos. that red sunset was amazing
Love your updates. Nicely done.
Beautiful sun sets. Really enjoy your videos.
Thanks for your video it was great seeing you guys again
Great video! Love the drone footage! Excited to see you already connected with Sundowner Sails Again in one of their vids!
NICE VIDEO
The sunset drone shot was awesome! Love the new chainplates, also. Cheers!
So nice to see Prism back in the water. You kids really had lots of work to complete before she was sea worthy but it all looks great! A belated Merry Christmas and Happy New Year to you both.
Great work guys! We've been watching your Baja episodes while editing our Baja episodes. Can't wait to see the next one!
great video... thanks again ....
Great video guys, and Prism looks awesome !
Nice drone footage. 😉
good vids thanks for sharing
Great video, love you both, and also really like the positive suggestions that your viewers are giving you. Seems like a great wealth of knowledge that would be a great resource for other boat owners to learn from. Keep up the great work and amazing pictures
You always do such a great job with the voice over... nice!
Always looking forward to the next. Great video and good information about Gyamas, hope to be following you down there in the next few years.
Fair winds!
Nice job..
Hi! For drill bits to last and cut properly, speed makes a big difference when drilling. Drill bits are not made to all go the same speed. Also the type of metal you drilling into dictates how fast and which drill bit to use. Stainless is a pain in the rear end ;) and you will ruin bits like crazy. I'm sure you dont have a bench grinder on the boat but a regular grinder could be use to file your drill bits. As long as you have a way to make the grinder stationary with the grinding disc vertical. For the angle of the drill bit, just use two nuts. Put two face of the nuts together to use as a guide for the angle of the tip. It works like a charm. I'm sure there is a video on here that will show you how to file them. It ain't rocket science. I paused the video at 3:26 to write all this. Now I'll go back to watching. Hope the two nut trick helps you out. Ciao! :)
good stuff
Hell yes, been looking forward to this episode!! Great job
Boat yard life, it's like work a few hours then take a break and go watch other owners work on their boat. 😉⛵
Hey what did Josh build that smooker out of ? Looks just right for a boat !!!! Fair winds and fair travels !!!!!!!
17:57 Jumping Rays tho :-)
In your next video, could you say more about the chain plates--how you sealed the bolt holes and fitted the wooden inserts?
plan on making a whole separate video on the chainplate install, there was just too much to fit in!
FWIW, I also have to service tapered Spartan seacocks. Friend of mine keeps bugging me to replace but not only is that a major headache, but I hear the ball cock ones only last maybe 10 years. Be gentle if the handle is frozen shut. I broke a handle off one and had to replace. I use a heat gun now and lightly tap with a rubber mallet to get moving.
The new plates give you some distinction, looks a bit like a Tall Ship.
Please makem longer and more often.
We would love to! as of right now we are at full capacity sailing, shooting, editing and uploading!
Those are some serious chain plates. You didn't take the old ones out?
Awesome! That is what we'll probably have to do. Where did you buy the chainplates?
its all on our website, but metal was from onlinemetals.com
Killer drone shots of the "marina". Did you get a new drone?
Well, its dead now, but yes we had a Phantom 3 onboard for about 4 months, then it went swimming....
Just saw this video this AM and too late now but John L. is right about the drill bits. Your bits are OK but you can't just bull your way through metal. Use a 'tap -drill' method and lube (even water is OK). Machine tools drill, back off for a few seconds and plunge again. CNC machinery will drill and back off so slightly and so fast you can't see it. This lets some of the lube cool the drill. Oil is used in a machine tool but I have successfully drill through 2" of iron with a 1/4 cobalt bit and a spray bottle of water. Drill bit is still good. Stainless is not as hard but is 'gummy'. It galls easily and doesn't make good chips.
We didn't go into much detail about the drilling process, but I did keep the bits cool, using water in a sprayer. Going as slow as possible. I plan on making a video covering just the chainplate process, it was a little to nerdy for the normal show.
I really enjoyed this episode... the machining, woodworking, etc. Quick question - what kind of wood is your bowsprit?
Primarily apatong, the scarf is sapele.
Caulk nutz and lube. Killer episode
hey there! Curious as to what the condition of your chainplates were when you removed them?
The originals are not removable. Since installing the bronze I have had them off once, they looked perfect. All the hardware was replaced with silicon bronze carriage bolts in 2018.
What is the name of the marina?
next time use the blue painters tape
Hi Guys, I really like you're channel. I've got a question on the footage of this episode. Is it from Christmas 2015? You're celebrating Christmas in a boatyard, while on the Sundowner Sails Again channel, you're on the boat in the San Blas islands. I'm confused... I should probably check your website.
it is a bit confusing, we are a year behind on our videos... sorry... Thanks for watching!
Cobalt drill bit plus lots of cutting compound. Moly disulphide.
John, are you sure about epoxy being able to turn liquid again? Never heard of such thing. What I do know is that epoxy shrinks as it cures and if it cures at 30C it will shrink some. Then if you ever see higher temperatures it will shrink more. That is why you sometimes cook parts at 70 celcius degrees to achive the highest strength and ensure the part will not shrink more. This is done after cure and the process is called post-cure. If the epoxy turned liquid again, post-cure would not be possible. Also, the way the epoxy chemistry works, I don't see how it would be possible to turn an epoxy polymer into the liquid state after it had cures unless you burned it and it melted. I would guess that under extreme weather situations that chunk of wood may have shrunk or expanded beyond the epoxy elasticity and the glue joint failed.
Thanks Luis, I how you explained it is what the original guy that explained it to me some years ago meant, but maybe dumbed it down for me to better understand. Didn't mean to confuse anyone, nor spread bad info.
GREAT video. Interesting design flaw in an otherwise stunning boat. Buried chainplates? Which are made of stainless steel and therefore need oxygen to properly protect against corrosion? Not a great idea, yacht designer man....
Wow! Talk about epoxy myths. Wood moves! Your bowsprit problem was not caused by epoxy, but by the wood itself, which expands and contracts with changing temps and humidity. Exposure of dried wood to high heat (like desert sun) can cause the wood to dry excessively, thereby causing it to "check" or split along the grain, especially hardwoods. The epoxy usually will not move with the wood, so the wood fails at its weakest point. Properly mixed and applied epoxy never fails within human living conditions, but the wood can, does, and will.
Great videos otherwise. Keep up the great work.
Probably the cause, thanks for the info!
