Why we built CARBON CHAINPLATES [E86] 

Mamma is a work horse for the boat! She is a real asset to your project.

Inspectors input was great ... you must feel so relieved getting such safety approval in this way.❤

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!

The "inspection" segments are always hilarious!

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!

Smart decision by your fab & paint sponsors Great exposure from both the build and (future) sailing episodes

Once again it appears you have passed the Cat Scan!!!CHEERS from Here!!!

I guess now the chai plates are glassed in, you could lift Duracell by them. 💪 great video 2x👍

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 chainplate could serve as a support arm for a salon table that can be stowed vertically against a bulkhead

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!

Surprised to see Evan's Zululand Yacht Club shirt. Very interesting. Didn't think anyone in BC would know of the Zululand Yacht Club

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.

Using the left over chain-plate as a folding dive platform for eels.

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

Great video you and your mom work well together and we appreciate the inspector

How about structure for the bowsprit for the old chain plate ? Nice work BTW

Looks like adult Matt has nailed reassembly! Fails chain plate becomes a paddle.

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 !!!!

Glad you were able to get the chainplate project done. Nice to see the architect visit. Thanks for the video 😁😁😁👍

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

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. :}

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 🏝️

Love the Inspector 🐈

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…

LOVED the Hammer from the inspector 🤣😂🤣😂

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 ".

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, 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.

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 😎

Awesome progress this week! Great work

I’m definitely captivated by the epoxy pour every time

it may not be captivating, but it is good advertising for your partner Totalboat! Having your Totalboat link in every description would make it easier to use, or on a Facebook page?

Use the chain plate in the windvane configuration. Cheers !

"Great at taking things apart, but not so good at putting them back together..." Lol what a classic mom quote.

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.

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.

I would definitely trust the laminated chain-plates the way you've done it rather than a couple dozen bolts / holes through my hull.

I can't imagine a better name on the stern of that wonderful sailboat, crossing oceans, than... MOM.

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.

I heard about your project a longtime ago, its truly made my morning to see how far your team has come. I can only imagine how difficult it is . I usually treat glassing videos with disdain, not with your team. Very professional and well thought out, watching handle those wetted sheets in the confined space, your braver than me, also much more experience also . I'm sticking to this channel from now on. I'm going to learn heaps. So glad i came across it .

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.

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.

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

In the movie Trainspotting, there is a sequence that would be shown every time the characters would use drugs. An idea for pumping and mixing is to make a drag-and-drop sequence you can use to convey this and use it as a transition into whatever comes next. You kinda already do that, but not as aggressively as the movie sequence from trainspotting. Nice editing though. The proof is in that you can take a boring process and make it interesting to someone like me, who doesn't even like boats.

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.

Hahaha! When the inspector tapped on the hull. Ah so good! I love it. Good times.

Thank you so much for sharing your build-process with us. Learning something every time with every video you release. You're awesome.

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.

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

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.

Spare chainplate could be used as a table leg, or a step up to the cabin roof, or a support for a folding seat at the chart table

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.

Good to see it's all had a good cat scan

The pumping of the epoxy should have its own theme music.

well done w the chainplates guys.. outstanding, thats a clap from me..

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.

Matt is a perfectionist and it’s over engineered 👍

Brilliant, good to see Evan there onsite. And the inspector is hilarious. Old chainplate, make some sort of kicker vang.

In to the space age, Matt, looking great.Thats one picky inspector, even went for the lick PH test 😂 Solid work mate

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.

I am new to this channel. It is very nice to see its a family project. Enjoy your time, I’ll follow from here :) My thought for that part: A chainplate for the backstay? Babystay?

Matt so awesome to see you saving Weight for All Wifely things lol . Matt will you make more Carbon fiber Hold Downs for the Rest of the Rigging? Will you be Running Dyneema Rigging ? Would you Change the Mast if you Find a Carbon Fiber Mast? Love how Mom is your Right Hand Worker. She did a Great Job Raising you Matt. Peace Be With You and Family

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

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 . 😊

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

Testing it sounds ideal for the build curious folks. I agree to that.

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. - 😏

Idea for the trash chain plate: Use it for the flush handle for the toilet.

Love the cat inspector 🙂

I like the angle that the interior volume of the boat is shown at 13:39. So much room!

The Swanson's Thrush in the background is cool (the spirally sounding noise)

So reassuring having a engineer to give his approval it’s great to think you’re doing okay! I think you surpassed his expectations

Cat inspector is fantastic!

Thanks to Evan from all of the Patreons and subscribers!

Ahh... Zululand Yacht Club. I've been there plenty of times. I went to school in Richards Bay, South Africa.

One thing I am curious about with the chainplates is the design it is layered one over the other which lead to a very strong structure but less surface area glued to the hull whereas if you had laminated them at a slight angle to each other creating say 2 tails at a slight angle to the straight up and down they would of been wider with more surface area glued to the hull. Of course the area you are gluing them is very small so you would not gain as much surface area.

Great explanation on the gluing! I am much more at ease with this procedure now.

Matt, get in touch with the Hydraulic Press Channel, make some testing on the carbon fibre chainplate happen. For science.

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.

these chainplates looks just FAN TAS TIC! What a job!

I finally got to snorkel in the ocean again, and got to say hi to a teenage lobster 🥰

Very impressive.

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

Very interesting video, thanks for bringing out the research, design, test, install part.

That inscrutable inspector though i was on the edge of my seat! Looking good 👌🏻

Congratulations on making it! Dreams come true! ❤ from 🇨🇦

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. 😎👍🍻

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.

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!

Duracell team making it look easy! Nice job! Keep rolling along! 👍👍

The old chain plate could be a very heavy duty hinge for the swim platform

Great composites documentation.

Looking good…. It looks super strong and incorporates a huge safety factor

Isn't there some irony using carbon fiber on a Mike Plant boat? Either way nice project. I hate to see that boat change, but I know that in the end, it is for the best.

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!

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.

Dinghy Davits worthy of a solid Gold Dinghy 👍

The inspector is taste testing now. Upping her game. Back to the cockpit now? Thanks for the episode.

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!!!
