Kit E55: Strip Planking Completed

[@tonyfromaus7855]

Thanks for sharing this journey. I admire your approach and stick-to-it-ivness. Great stuff. Just wanted to say that Brian is a hero. Great dedication and work ethic with a sly smile and dry humour. Best wishes for the build.

[@SailingSVLynx]

Yeah, I couldn't do this without Brian. But don't tell him, his head is already too big. He might want a raise! Let's see, zero times zero, carry the zero...

Y'all are doing a fantastic job, I am amazed at how much a few skilled and determined people can accomplish! It is getting very exciting to watch your dream vessel take shape! Thanks for making these great videos.

[@SailingSVLynx]

Thanks for watching and the kind words! We are definitely determined... skilled? Well, we're learning as we go.

[@rhyslightning3379]

Great job guys! Huge milestone reached and I don't think you could have done it any better or faster while learning it - the second hull has shown your obviously progression in your skills! Very impressive in my opinion 😉now that you are pros at strip planking, let's hope you never need to use those skills ever again! 😅

[@SailingSVLynx]

Here's to that, cheers! Now I want go float on my hulls for some time, telling stories about the time we were crazy enough to build a boat.

[@jakobusphsteyn3500]

Weather forecasters are like politicians, never belief a word they say but be prepared for all eventualities.

[@SailingSVLynx]

No doubt!

[@opcn18]

I really appreciate the pro-commenter attitude (being a commenter myself). As much as I darkly enjoy some schadenfreude when someone who was nasty to commenters learns that people really did know some things in the comments I enjoy seeing a good community and a good boat get built more!

[@SailingSVLynx]

We learn stuff all the time from the viewer comments. If nothing else, we do research into some suggestions to see if that's something we want to adopt. Either way, we learn something new.

[@_mysilentblue2227]

Loving the progress.

[@SailingSVLynx]

Thanks

[@glmaguire]

G’day - very impressive project. Looks,like you’re tracking,pretty well to your original timeline.

[@SailingSVLynx]

At this point, we think so. We'll see when we get to the finish work in the second half of the build.

[@JamesBond-xq3tw]

Power plane on the squeeze out ,might save some time ?

[@SailingSVLynx]

We attack it with a flap disk attachment on an angle grinder, works well.

[@jimlofts5433]

hmm what was missing from finishing the whisky plank on the hull - cheers

[@SailingSVLynx]

Well, we did that off camera ;)

one "comment" added enjoy

[@SailingSVLynx]

lol, one reply added.

[@normanboyes4983]

Great progress. On the BMS current handling situation - is you battery building partner engaged with the modifications. In addition if the BMS are handling the full current draw should they not be mounted on a heat sink and outside the main box? Looking forward to the post mortem on the short from your sparky and Victron comments on its kit.😀👍⛵️

[@SailingSVLynx]

They will only use full current draw for short periods. Most of the time they will draw a lot less. I wouldn't want to put the BMS units outside the waterproof case as they would corrode much faster. We have a temperature readout and will monitor the temperature. If they are getting too warm, the BMS will also shut them down. If this is an issue, we can add a water cooling system.

[@michaelm2683]

I feel like the squeezed out epoxy should be squeegeed down to within a few mm to force into any voids and especially to reduce the sanding but your past that now 😊

[@SailingSVLynx]

We started doing that about halfway through this hull.

[@1littlelee]

Look into LTO cells, they are MUCH SAFER (cant explode etc...) and also hold an ENORMOUS amount of amps

[@SailingSVLynx]

We looked into all available battery chemistries when designing our batteries, including LTO. That is a very nice type of battery with one issue, weight. On a performance catamaran, like S/V Lynx, keeping the weight down is critical. Our batteries weigh about 200 pounds. less than what LTO would weigh for the same amp hours and voltage and LifePO4 chemistry is also very safe.

[@peterhoffman2597]

since your going to leave eooxy unscraped could you use a hand power plane to initialy start using to fairing the hull

[@SailingSVLynx]

We used a flap disk on a angle grinder, which works very well. We'll show you in next week's video.

[@ctown6971]

Can you use the fine/trim tool to cut off the bulging epoxy between the strips?

[@SailingSVLynx]

It is easily removed with a flap disk, we'll show you next week.

[@DVolvoguy777-x7o]

Electric hand plainer work for making short work out of removing the squeeze out? Just curious. And an idea if you hadn’t thought of it. Great progress. What was the total time on planking the second canoe? I estimated 1.5 Wk. excellent video! Thank you!

[@SailingSVLynx]

We found that our angle grinders with a flap disk attachment work well for getting the squeeze out off fairly quickly, you'll see how that goes next week ;)

[@alqubes]

in hindsight would it have been better to make the canoes in a Mold ?

[@SailingSVLynx]

Well, a mold would cost us about between 100k and 300k to have it made. That works well for production companies making many boats in the same molds, but not so much for a single build. Life on the Hulls used a mold, but they found a used one for sale somewhere. There aren't any molds made for a Solitaire 1520, since this is hull #1.

[@Dodgecramer-wj6xv]

Regarding the strip planking I wonder why you not remove the squeezed out epoxy glue with a spatula immediately before it gets cured and in addition remove the rest with acetone. That will save you a lot of work afterwards and will reduce sanding a lot.

[@Dodgecramer-wj6xv]

May be acetone has a bad effect on the foam, removing with spatula would be enough to reduce sanding to a minimum

[@SailingSVLynx]

As epoxy cures it shrinks. If we scrapped off the excess (which we did on the port hull), after it cures, you have to fill the lines that shrunk between the planks (which we had to do). That caused a lot more work than sanding off the excess. If we were building a third hull (thank heavens we aren't) we would go in-between and try to scrape off most of the squeeze but leave some high. We did this on the second half of the planks on the starboard canoe and that worked out best.

[@Dodgecramer-wj6xv]

@@SailingSVLynx with all the silica you put into the epoxy the shrinking rate should not exceed 0,5% and that will be automatically filled if you put on the basalt. Even if you have to fill with a spatula if there is some too much shrinking, it would be less work than all the sanding. Everybody who is all the time working with epoxy will tell you this.

[@SailingSVLynx]

@@Dodgecramer-wj6xv We did it that way on the first canoe, it cost is far more work. The second hull took far less time.

[@captainsensible298]

Just a question, Why does the design not include an outer laminate covering the entire canoe form ? It seems as the design is relying on the butt joins of the strip planks.

[@SailingSVLynx]

It does. We apply that soon. You can watch us doing that on the port canoe in our video, Episode 46: A Stone Hull?

[@mckenziekeith7434]

Adding waterline will also cost you every month you spend in a marina. Just something to keep in mind. This is directed more at the people who asked about it than you guys.

[@SailingSVLynx]

Another reason to avoid marinas. ;)

[@pauld9530]

I think you decided to make a cat so you have 2 whiskey planks 😂

[@SailingSVLynx]

Our secret is out!

[@briantasse5257]

I'm with you Paul! Cheers 🥃

[@roberts8783]

what are the planks made from ? we're you working in a trade before like carpenter etc?

[@SailingSVLynx]

Other than a few places, the entire boat is made from vacuum bagged fiberglass covered foam; light and strong.

[@WJSpies]

He didn't have a pint of whiskey after putting in the "whiskey plank" - he skipped an important irreplaceable stage of this boat's assembly. Maybe it's cursed now, and doomed to sink.

[@SailingSVLynx]

And how do you know what we did and did not have?

[@Bigfish300]

Nope. The OC tender only weighs 86 pounds and not 500. I think Nikky and Jason proofed that it doesn't flip that easy

[@SailingSVLynx]

The OC tender isn't the heavy weight, that's carbon fiber, its how much the lithium batteries and jet weigh. But weight isn't the main issue, any dinghy can be flipped in a surf entry or exit.

[@SailingSVLynx]

And then there is the price... $14,000 was quoted to us for the OC400 and about $15,000 for the jet and batteries. That's a cool $29,000 total. Unfortunately, our channel is not the size of the Wynns, so we don't have that kind of income for a dinghy and if we did spend that much, we wouldn't risk it on a beach entry.

[@Bigfish300]

The jet only weighs 40 kilo. Less than your engine and fuel tank. I by no means try to compare your financial capability to that of Jason and Nikky, but merely wanted to correct you on the 500 pound weight claim. Total weight, tender, jet and battery on the 350 is actually 137 kilo, just about half your claim.

[@SailingSVLynx]

@@Bigfish300 Well, we'll have to disagree here. I looked up the Zero Jet with two battery option, and the article says it weighs 174kg for the Jet and batteries. The Tender was not included in that weight. As for the OC Tender, I was not quoting the weight of the Wynns tender, but the OC400 and Zero Jet with two batteries, which is the tender we discussed purchasing with the sellers. That OC 400 tender weighs 67 kg. So, the Jet, batteries, and OC400 tender weigh 241 kg. Which is 531 pounds.

You are obviously a very smart guy. Why are you not wearing safety glasses when you are cutting material? I’m not trying to be a Karen, but glasses are cheap, eyes are PRICELESS.

[@SailingSVLynx]

I do, and mostly I have them on, just forgot in that shot.
