Starboard Composite Chainplate
Вставка
- Опубліковано 5 вер 2024
- Of course, if one chainplate is pulling out of the boat, the other one is not far behind. This week we are fixing chainplates, shortening forestays, digging rot out of the windows, and everything in between as we desperately try and get Paikea ready for another Atlantic Crossing.
We showed our rudder-making process as a separate video series but in reality, it was all going on at the same time as everything else. When you are working while you cruise and trying to upgrade your own boat, things can get a little hectic. Harry did get the opportunity to do some sailing on a Diam24 so its not all hard work (at least not for the 12 year old).

not only are you building your own chain plates ect BUT YOUR DOING IT ON THE BOAT AT SEA !!!!! now that's a REAL TRADESMAN
Love the kids getting involved! Something to look forward to !!
And at the end of the day that's what it's all about. Adventuring together.
Great to see the kids involved in projects and filming, the apprenticeships have started!
Wonderful video! … Such a pleasure observing a master. The starboard chain plate fit/finish benefitted from your earlier port chain plate iteration! My Trimaran is built primarily of Kevlar, now I don’t look forward to future repairs using that material (thanks for the warning). You mention working with e-glass and carbon fiber. Are there any advantages using s-glass versus e-glass? Maybe it’s simply a lack of availability on remote islands.
Yes there are advantages to using s- glass over e-glass in every way shape and form. The biggest problem with it is availability and cost.
Interesting to see a very skilled composite engineer at work chain plates one of the most loaded parts of a boat so laminate schedule withheld but how it’s executed and integrated back into the bulkhead for all to see.
Monumental effort, doing that on anchor at St. Martin is akin to the Apollo 13 repairs to get back to earth 🙂Well done!
Cool Family!
Master shane at it !
He had all the kids busy this time!
great job.
Thank you for the kevlar reply. As an interested novice the specifications for kevlar tensile strength wise looked excellent. But all materials must be workable. In my field titanium alloys and steel alloys compete but steel being much easier to work wins.
So impressed 😊
Go Harry! 3 hulls are the best unless you're full-foiling ;)
3 hulls are awesome 😎
Carbon has the least elongation in an ama wrestle. 💪
When can Harry and oli come play on race boats with us again in St Maarten?! Cool diam footage!
Ha! He was so gutted he had the camera pointed too low! Harry says hi!!!
so - when are you going to hire the boys out ? what are the child labour rates like in Europe ? Do they know that they will have back rent as well as room and board to pay back when they hit 18?
On a more serious note, what are your thoughts on the most appropriate places (if any) to use basalt fibre/woven mat for a non-racing boat ?
They spent a couple of days tightening the trampoline nets on an HH66 and earnt more money than me! 🤣🤣
Carbon for chainplates. Makes you wonder why not every boatbuilder is doing that. Let me think: superconductivity, breaks without warning, doesn’t bend as good as steel, doesn’t absorb shockloads as good as steel. And: eventually a chainplate klings to your boat by friction. Carbon has the least surface friction.
And that's why you're not asked to build America's Cup entries, Ocean Race IMOCAs, Ultim tris or the many high performance brand boats offered today. Yes it takes more skill and time to do proper carbon fiber work. And the results in this composites chainpate tech has been proven.

@@Ravenswingsailing I can imagine when the fabrics of the chainplates are integrated into those of the hulls that you can get a strong bond, but when the chainplates are made separately and are attached lateron the structure more or less depends on the “glue”

What e-glass/carbon clothes do you keep in stock aboard, in which quantities? And what sort of epoxy, in which quantities?
Do you use any CDB between a batch of the carbon unis? That was the practice where I used to design but I never thought "is this really necessary?" until I saw your work
I don't use CDB in this laminate. That was the thought process once upon a time but nowadays it's becoming less common as it introduces new interlaminar shear failures between the planks/stacks
Great job on completing all of these critical boat projects with such a time crunch! Why wouldn't you just say how many layers were on the chain plates :P The number of layers is kind of irrelevant any ways since it depends on what weight cloth you use. You gave us the thickness which is the more important metric.
🤣 Shayne was just teasing Olly
Ah you guys are silly :) all in good fun.@@youngbarnacles
why not try raptor bed liner like ross in ozz has done on his cat instaed of liners might need a bit of fairing first but must be lighter.
Hi Shayne, which epoxy laminating resin available in Australia would you recommend for carbon composite work? Thanks.
Check out Adhesive Technologies in Australia. Their ADR range is very good
@@youngbarnacles Thanks Shayne, I really appreciate it.
No worries
I am interested in your new sail: what did you buy and why? And by "what" I mean membrane, 3di, hydranet, dacron. And what design choices did you make with regard to details: draught % etc
We're getting to the sail discussion 👍
@@youngbarnacles I have just been through the process myself. I have a Sundeer 60. In my opinion the loads are too high for Dacron, even though that's what most Sundeers run. The stretch numbers for the Spectra reinforced woven cloth are not great and it's very expensive. So that leaves laminate, membrane and 3di. North's offer 1 year warranty on 3di and it's very expensive and dealing with North Sails is often....less than optimal. In the end I bought carbon and Twaron reinforced membrane sails from Evolution Auckland for less than another Sundeer has bought Dacron from North's. I am very happy with them: less heel, more go, better height upwind.
@@deerfootnz good to hear the lads at Evolution looking after you and good to see more options for those wanting a decent sail at a competitve price
