I can understand why folks questioning the carbon chain plates, because it is something they not use to seeing. As a retired naval architect / professional engineer I know they are plenty strong; the only chance of failure would be in the glue line or secondary bonding. Given the vacuum bagging and prep work that Matt does this is highly unlikely to fail.
The cat inspector was the best, loved the tapping with her little hammer! Man, that first wide layer of fiberglass was a monster, a stress monster, so much more manageable with them cut in half. What a great job though, I’ve never seen anything like that, pretty impressive!
Tapping the new chain plates is like checking a friend's new car, you kick the tires a bit and nod in approval. I love your videos Matt and Janni. They're inspiring, educational and fun to watch. Can't wait to see Duracell float again!
It is ridiculous how much I love this channel. Think of me as a Duracell groupie!!!! You two are naturals in front of and behind the camera. A real pleasure to watch your project come together.
The chain plate could be used as a collapsible bow sprit where the anchor chain runs out over the end. Then fold the chain plate back up toward the boat to make the boat a little shorter thus easier to maneuver in tight places. Just a thought!
Reassuring that the chainplates not only passed the naval architect but also the CAT scan - now if you had a retriever or course, then a LAB report would never be a problem - possibly challenging if the LAB technician and the CAT scanner were on site at the same time !!!!
One of the main and many reasons I watch your channel is to teach myself to slow down and do a job right . I get too impatient sometimes and short cut a project. I am very impressed with your overall vision for such a large project and the determination to do each step properly.
Ah, the PNW is such paradise. It is so hot and humid down here in Georgia right now that I cannot get any work done outside without soaking t-shirts in ice water and changing every half hour or so.
In another lifetime, family owned a business that used a chopper gun for fiberglassing. Essentially a rotary knife cutting twine in short pieces at the same time you are spraying the epoxy. The roller we used the most was a brush rather than a paint roller or the ribbed plastic or aluminum versions. It was better at “puncturing” the bubbles to get things to lay flat.
Hi guys, wow what a good job you all are doing Matt you have a one beautiful mother it is wonderful to see her coming to help you guys and sometimes your dad turns up. He must be busy doing something else but you’re so blessed to have a wonderful family , Cliff from Logan City Queensland Australia 🇦🇺 from the big island 🏝️
After seeing this I understand your answer when I asked about spreading out the load. That is a wonderful solid design! In theory the load inwards should be minimal, but if it occurred nevertheless, it would concentrate stress at the top of the chainplate bonding and what you did today spreads out that load you shouldn't be getting. A race boat is built for racing. A cruising boat is best built for the unexpected.
Those chain plates look so good in there. Fiberglass is such a pain to work but when done right(after a thousand times) it’s very rewarding due to the usability, performance, looks and etc…
Matt, I know that Duracell HAS to have fore and aft, upper and lower shrouds on both sides. Where are all the other chainplates? Are you going to have running back stays? Are you going to have an inner forestay? Are you going to have more than one backstay? Are you planning a solent rig on the bow?And the forestay needs a chainplate also, two if you are going with a solent rig. As I see it, there may not be enough time this year to do just the rest of the chainplates! As far as the "not to be used" chainplate, I had suggested asking Lloyds of London if they are interested in testing it. Big insurance companies might want to know. But personally I would hold on to it as it is very likely quite adequate for any other chainplate duties.
From where I sit there doesn’t seem to be any question about your design, construction, methods or solutions. You are the toughest critic and would not be willing to risk anyone’s life on that boat. Besides, Mr. Plant set the standard of Duracells construction quality for you to follow. Keep up the great work before you know it you will be sailing her.
Matt, your Mum is an absolute beast, I admire her immensely, she always seems to be there at the most opportune times to help out. You two obviously have an awesome, deep connection and you can see she is just so proud of her little boy and what he’s achieving. I was really interested in what the engineer had to say especially about point loading etc and I completely agree but there just seems to be something about a bolt going through two pieces of material that seems more reassuring, however, saying that and watching what you are doing with fibreglass is an amazing display of modern technology and know how especially in the advancement of glue quality now as they are so high spec. . Matt if they ever decided to immortalise you it won’t be a statue in bronze but rather fibreglass
I have no idea why I watch this channel, but I do. I always click like because i enjoy following your adventures, I can't wait for the splash. Carry on carrying on. :}
18:00 Obviously, please yourselves first. If you end up doing destructive testing, please document the hell out of it because 1) science 2) SCIENCE!!! And you'll have at least two parts to auction off 😎
You have probably already layed up the other side, but I was thinking it was the over head portion of the layup that was the problem as it was too heavy with resin to stick, but the side portion could be pre-wetted to save some time, and the over head portion of the same sheet could be wetted in place as you already do. Love the " cat scan ".
I have zero interest in sail boats but I love the fab work and would like to do more epoxy and less polyester/vinyl ester in my boat builds, these videos are awesome
The whole project is amazing . But you are taking this to a whole new level . You are introducing other sailors to a new building process. Best you and I'm sure she will be bomb proof in the end. Angus. SV Violet Walters
I too dismantled a lot of things as a child, it was some time before I learnt how to make them work again. It's a great apprenticeship, there's not much I won't have a go at fixing or building now.
Terrific progress! That was great to see the engineer stop by and approve of your work! Thanks for all of the explanations, and putting some fears to rest. Great video as always, and keep it up.
My guess is the extra chain plate could be part of a hinge for a droppable transom that converts into a swim platform. It just feels like one side of a hinge and a swim platform would need some pretty strong hinges.
We always look forward to the vacuum pump going on your glassing!! The strength that the vacuuming adds must be amazing and the finish is better. We don't see other boat builders using this method.
Good episode. I now feel 5% more confident the chain plates won't fail. I think the load test is your best idea for the extra chain plate. I'm curious about the three slots at the top of each chain plate. This connection area looks like a weak link. Test this area for strength.
Looks like you have no idea what you're talking about. Matt is too polite to reply and only gave you a like.... lol. The slots are for the different rigging... D1 or D2 and Vs. The connection is at least 10mm thick. 10mm of carbon unis can lift your house. It's fine.
The Inspector seemed quite pleased with the chain plates, a good sign. A testament to the power of Mom's, at this point I'm convinced Matt is just a pretty face for the camera.
Use the scratch chain plate for a flip up tiller handle. ... because every sail boat needs a flip up tiller handle. ... for the door-pull on an interior bulkhead door. - 😏
I need stock in total boat for real this boat a.k.a the Abrams tank your building will be insane when complete just epic really cant wait to see her sail and i wouldn't upset if you wrapped it in carbon black and did orangy teak decking to make it look like a battery i think she would be amazing
Maybe use the unused carbon chain plates for bow or stern stays or for giant hinges for a stern platform or hinges for stern Davitts??? Wow, that was a lot of layers on top of the carbon but I thought it would be more desirable to have a larger surface area to spread the loading over a wider area! Or what about continuing the overlays all around the lower hull and joining up with the future keel attachment area and back up the other side to the opposite chainplates and maybe then across the deck strengthening the mast base area and back to the first side??? That would then make a sort of space frame, or would it? So many things that can be done with this technology! Best of all, Kitty can then check it all out!!! Maybe there is a song there, or a poem??? SkipRay, Kerry, Ireland.
Thanks for the explanation of how the carbon fiber chain plates work vis-a-vie the glue joint to the hull. It is truly amazing that thickened epoxy when used as an adhesive over what looks to be a surface area of about 1 square foot can handle a sheer load of tens (hundreds?) of thousands pounds. So awesome. Quick question, if one were building a hull from scratch, could one integrate the carbon fiber chain plates into the hull itself?
Yup. The reason we did them on the inside of the hull was because it we lapped them over the hull on both inside and out, you would have a 16mm strip of carbon on the outside standing proud of the hull surface. This would have to be faired over a very large area to make it smooth and disappear.
It’s going to get a hardox tip fitted and be the one and only pawl for a REALLY BIG all Carbon winch. Or, a heck of a bow roller sprit that’ll have a just touch of springiness for shock absorption under bigger snatch loads. Or, a cool emergency tiller? 🤷♂️ No worries here about the chainplates’ glue area. Nicely done Cheers, R. 😎👍🍻
Another great episode... thanks again for bringing us all along on this project. While I am certain there'll be loads of great suggestions, I'd like to offer up the idea of either a pivoting seat or step. Looking forward to whatever you guys elect to do!
When you were painting the chain plate the metal of the paintbrush tapping against carbon fiber created a noise I didn’t expect. It sounded like…ceramic? Brick? The sound of charcoal briquettes being poured from a sack!….I guess that would make sense…carbon.
I’ll never refer to myself as an “Expert” in any form… An “Ex” is a has been!!! A “Spert” is a drip under pressure…. I’m 66 and would like to think that I have an above average knowledge of “Common Sense “… although there are those situations where that could be argued!!! I’m restoring…. Rebuilding a 1988 Wellcraft Center Console Bay boat… new floors, new transom… adding a new additional fuel tank… installing a new console and T top… and an Armstrong Engine bracket… I guess if I am completely honest… I should say I was doing that… the project has been on hold now for a few years due to multiple cancer diagnosis’s… and being severely mauled by a dog!!!! Enough rambling about me… I absolutely love the carbon fiber chain plates… and agree completely that the 15 layers of fiberglass is hands down making them bulletproof… or at least making their attachment points bulletproof… With this said… am I correct in saying… that where the shrouds attach…to the chain plates is now the weakest link????? My understanding is… “If” there’s a catastrophic failure…. It shouldn’t happen with the chain plates ripping loose… but still could happen at the shroud attachment points… Do you have any thoughts as to what the strength is at those points… Keep doing what you’re doing!!! Even if I’m not able to work on my boat… I’ll get a tremendous amount of satisfaction in watching you build yours… I’m a 100% Service Connected Disabled Vet… and go back to the VA hospital in Houston tomorrow morning for more biopsies… This is cancer # 5 in five years… number 3… in the last year alone… I’m truly blessed…as 100% of my medical is paid for… I’m tired of fighting… but still doing my best to keep my head up and move forward!!!
Matt, the only thing I can think of is the torsion on the connection where the chainplates come out of the hull. I'm not exactly clear about the connection to the rod or wire shrouds. If there is a way for the type of turnbuckle to absorb the torsion forces so that they aren't transferred to the carbon fiber chainplate that would be good. Not sure if I really know what I'm talking about but, outside of that, they look bomb proof. Keep up the excellent work and you have one heck of a mom to help as much and as well as she does.
The chainplates should be (and look to be) aligned with the shrouds. Also, the turnbuckle/toggle assembly gives rotational freedom in multiple directions.
My guess is the chainplate will be used for an emergency tiller! Btw, curious about the stainless tube insert in the carbon. Heating/cooling of the steel puts tremendous strain on the epoxy overtime as the metal expands and contracts, resulting in cracking, and delamination. This can be seen with alloy bottom bracket inserts in carbon bike frames, hence why most bottom brackets are now entirely carbon. This problem will occur anytime you have metal bonded to composite. Hope this helps! Cheers!
2:39 Guys, next time you need to show video of an off-road motorcycle during the electric shears segue!!! To randomly see a motorcycle gassing it through the dirt long enough for our brain to ask: "what's happening here?" Then switch to the shot of the electric shears. The audio stays the same but the visual changes. And yet matches perfectly for BOTH scenarios . 😊
With a massive safety factor and weight built into chain plates one wonders where you stop. At the top of the mast ? At the cross trees . Bow sprit ? It all comes down to the weakest link and everything else is superfluous and doesn’t lend itself to that design of hull.
Hi! Loving the project! I understand the benefits of laminating the chainplates, but the previous chainplates were bolted directly to the knees, weren’t they? This takes the load to the string points designed for the purpose. I presume the fibreglass laminate does the same.
Fortunately Matt went on as a young adult to learn from shipwrights the arts and crafts of building contemporary boats. I find that it makes for relaxing and rewarding YT sailing channel viewing when project are led by trained shipwrights like Matt here and Aladino with Magic Carpet.

Surprised to see Evan's Zululand Yacht Club shirt. Very interesting. Didn't think anyone in BC would know of the Zululand Yacht Club
Richard's Bay was the first South African stop in our family's 8-year circumnavigation. Had to get the t-shirt.
Once again it appears you have passed the Cat Scan!!!CHEERS from Here!!!
The chainplate could serve as a
support arm for a salon table that can be stowed vertically against a bulkhead
Love the Inspector 🐈
Smart decision by your fab & paint sponsors
Great exposure from both the build and (future) sailing episodes
The chain plate could be used as a collapsible bow sprit where the anchor chain runs out over the end. Then fold the chain plate back up toward the boat to make the boat a little shorter thus easier to maneuver in tight places. Just a thought!
I guess now the chai plates are glassed in, you could lift Duracell by them. 💪
great video 2x👍
How about structure for the bowsprit for the old chain plate ? Nice work BTW
I was about to suggest it.
@@ghislaindevouton1553 same here. but it would need to be longer I'd guess.
Using the left over chain-plate as a folding dive platform for eels.
Reassuring that the chainplates not only passed the naval architect but also the CAT scan - now if you had a retriever or course, then a LAB report would never be a problem - possibly challenging if the LAB technician and the CAT scanner were on site at the same time !!!!
LOVED the Hammer from the inspector 🤣😂🤣😂
The Swanson's Thrush in the background is cool (the spirally sounding noise)
Yes! Good ear.

Looks like adult Matt has nailed reassembly! Fails chain plate becomes a paddle.
Thank you so much for sharing your build-process with us. Learning something every time with every video you release. You're awesome.
Maybe look into getting a portable air conditioner for inside the boat during the build. You can contain the cold air with plastic sheet or blankets
it doesn't get that warm here that often, even during the summer.
Ah, the PNW is such paradise. It is so hot and humid down here in Georgia right now that I cannot get any work done outside without soaking t-shirts in ice water and changing every half hour or so.
Forward stay?

It's great to have your architect-engineer Evan working on site, side-by-side.

Testing it sounds ideal for the build curious folks. I agree to that.
Brilliant, good to see Evan there onsite. And the inspector is hilarious. Old chainplate, make some sort of kicker vang.
Thanks to Evan from all of the Patreons and subscribers!
I like the angle that the interior volume of the boat is shown at 13:39. So much room!
The inspector, I love it!! 17:18
I would definitely trust the laminated chain-plates the way you've done it rather than a couple dozen bolts / holes through my hull.
Great composites documentation.
Congratulations on making it!

Or, a cool emergency tiller? 🤷♂️
No worries here about the chainplates’ glue area.

I think the redundant chainplate would actually make a cool (slightly springy) seat support for the workshop /worktable/desktop.

On to a new project next week.
I’ll never refer to myself as an “Expert” in any form…
An “Ex” is a has been!!!
A “Spert” is a drip under pressure….
I’m 66 and would like to think that I have an above average knowledge of “Common Sense “… although there are those situations where that could be argued!!!
I’m restoring…. Rebuilding a 1988 Wellcraft Center Console Bay boat… new floors, new transom… adding a new additional fuel tank… installing a new console and T top… and an Armstrong Engine bracket…
I guess if I am completely honest… I should say I was doing that… the project has been on hold now for a few years due to multiple cancer diagnosis’s… and being severely mauled by a dog!!!!
Enough rambling about me…
I absolutely love the carbon fiber chain plates… and agree completely that the 15 layers of fiberglass is hands down making them bulletproof… or at least making their attachment points bulletproof…
With this said… am I correct in saying… that where the shrouds attach…to the chain plates is now the weakest link?????
My understanding is… “If” there’s a catastrophic failure…. It shouldn’t happen with the chain plates ripping loose… but still could happen at the shroud attachment points…
Do you have any thoughts as to what the strength is at those points…
Keep doing what you’re doing!!! Even if I’m not able to work on my boat… I’ll get a tremendous amount of satisfaction in watching you build yours…
I’m a 100% Service Connected Disabled Vet… and go back to the VA hospital in Houston tomorrow morning for more biopsies…
This is cancer # 5 in five years… number 3… in the last year alone… I’m truly blessed…as 100% of my medical is paid for…
I’m tired of fighting… but still doing my best to keep my head up and move forward!!!
In to the space age, Matt, looking great.Thats one picky inspector, even went for the lick PH test 😂
Solid work mate
she has her methods!
Matt, the only thing I can think of is the torsion on the connection where the chainplates come out of the hull. I'm not exactly clear about the connection to the rod or wire shrouds.

The chainplates should be (and look to be) aligned with the shrouds. Also, the turnbuckle/toggle assembly gives rotational freedom in multiple directions.
Chain plate converted into a unique block as part of the rigging?
Answered questions that I didn't realize I had
My guess is the chainplate will be used for an emergency tiller!
Btw, curious about the stainless tube insert in the carbon. Heating/cooling of the steel puts tremendous strain on the epoxy overtime as the metal expands and contracts, resulting in cracking, and delamination. This can be seen with alloy bottom bracket inserts in carbon bike frames, hence why most bottom brackets are now entirely carbon. This problem will occur anytime you have metal bonded to composite. Hope this helps! Cheers!
Dont you have a bow to fix still ? Incorporate the 'plate ' in the bow repair , or better yet incorporate it with anchor windlass placement

To randomly see a motorcycle gassing it through the dirt long enough for our brain to ask: "what's happening here?" Then switch to the shot of the electric shears. The audio stays the same but the visual changes. And yet matches perfectly for BOTH scenarios . 😊
With a massive safety factor and weight built into chain plates one wonders where you stop. At the top of the mast ? At the cross trees . Bow sprit ? It all comes down to the weakest link and everything else is superfluous and doesn’t lend itself to that design of hull.
Love this build. The best !
Hi! Loving the project!
I understand the benefits of laminating the chainplates, but the previous chainplates were bolted directly to the knees, weren’t they? This takes the load to the string points designed for the purpose. I presume the fibreglass laminate does the same.
The old chain plate could be a very heavy duty hinge for the swim platform
Was good to see Evan there to see the project firsthand. Curious to see what you will use the extra chainplate for. Love your channel.
"Great at taking things apart, but not so good at putting them back together..." Lol what a classic mom quote.
Fortunately Matt went on as a young adult to learn from shipwrights the arts and crafts of building contemporary boats. I find that it makes for relaxing and rewarding YT sailing channel viewing when project are led by trained shipwrights like Matt here and Aladino with Magic Carpet.
