    Default Flywood Canoe Nesting Version

    I've wanted to build a nesting canoe for a while now, but was not fully satisfied with the looks of nesting boats available. However during my research I came across the awesome work of FloMo, so I decided to cut one of his designs into three pieces (and mess up the beautiful sheet layout...).
    I think I may actually be the first person (?) to build the large version of the flywood canoe/rowboat, however I made a few changes: The waterline beam has been reduced slightly to 75cm, and the sides are less angled, and slightly curved, which is made possible through the bulkheads necessary to be able to bolt the sections together.
    So far, the build goes well, with the mid section almost complete, and the bow section getting folded together (and hopefully not cracking due to my choice of pine plywood...) tomorrow.
    More pictures to come.

    Well done so far - I'm looking forward to seeing more as she progresses.

    I'm looking forward to seeing how this comes out too...
    I'm kind of amazed at the sweet curve you got in the center section. Don't quite know how you managed that...
    Good luck going forward.

    Over the last weekend there's been a little progress: The bow section's plywood, despite being of the cheapish and stiff kind, has accepted its new life as a bizarrely curved object without a problem. I was surprised of how little tension of the straps was required to hold the shape after it had been folded up - kind of fascinating. After the stitches were in (that proved a little harder, maybe due to the fact that the shape deviates slightly from the plans...), the shape held together by itself, and was epoxied and taped on the inside like the midsection. The curved shape was possible due to the bulkheads. It's only present in that area though, so I am not sure whether I would do it again. In the next step, I'll be glassing the outside of the sections. Concerning the finish, I have planned to only paint the inside as I don't like the thought of having to sand all of it like the outside, especially given the complex shapes with all those bulkheads... I hope that if the inside is dried with a towel after use, that'll be fine. I have also read that epoxy-coating the inside can cause problems when the coat cracks (might happen with the thin floor?) and traps water in the plywood, which leads to more cracks... What would you advise me to do?

    looks awesome! I think I'll give this a go.... I want to build as a rowboat to pull behind my bike, and on our roads here in BC I don't want to try pulling a boat 16 feet long! Can you share the measurements on hull where you made it into 3 pieces? I'm considering making the entire hull first, with double bulkheads, and sawing it into pieces afterwards between the two (saw a dinghy made this way!)

    Meanwhile, after fixing some mistakes I made, all sections are completed and will soon receive their gunwales. It turned out that building the boat in sections really complicated achieving a smooth shape that otherwise forms naturally. So, @WestCoastFibreArts, I think you had the right idea. I would also have done it that way, if only I had the space for that...
    To answer your question, the boat is the original length (465cm), sectioned in a way that the longest section fits in a VW Golf Variant (165cm), and the other sections respectively being 20cm shorter than the previous one, so that they fit into each other nicely. You can probably instead make the second section 10 shorter than the first one, and the third 30cm shorter than the second one, looking at my boat. This gives more room in the bow (second section) to install a buoyancy tank, I figured...
    Btw I also dreamt of a bike trailer for it so I can't wait to see what you come up with!

    I think you did a fine job , as far as the potential for cracking ( checking ) on the inside of the bottom hull sections , unfortunately , I think the only way to stop that is to lay down a layer of light glass .

    As far as I can tell by now, even with my very cheap plywood with its heterogenous structure, the potential for cracking is not very high - after the outside is glassed as usual, of course. The tension in the wood when folding them was surprisingly low, especially when it is folded all the way up, contrary to what one may expect before. This shows the true genius of Flo Mos idea...

    thanks so much for the measurements. Do you know about how much epoxy I will need? Can't wait for more pics

    In any case, always way more than you think before So far, I used 2 litres and I haven't even glassed the outside yet. That should need at least another litre. As for the measurements I can post the crude drawing later that I made based on FloMos cross sections drawing to determine the shape of the bulkheads.
