    Default Couple of skin on bamboo frame boats

    I'd call one a kayak, and the other a canoe kayak cross? It was a warm one over the summer and my son and I got tired of being dry. So, without any plans, we set to build these. The frames are all 100% lashed, and the skin is 12 oz canvas drop cloth coated in outdoor latex. I looked at plastic yaks to get an idea for basic dimensions. They are 12 feet long. I do plan on reworking them to just give them a basic upgrades, better lashings, braces, etc.

    As soon as I figure out how to post images I will

    So here is the collection of materials from my yard. My son and I spent the entire day harvesting this stuff to process. Made a nice fire afterwards with the tops and branches. Lots of fun pops and bangs

    Here I bent and tied in a frame of split bamboo. This gave me an idea of depth.

    This is how I decided to notch and insert the stringers into the stems. I plan on redoing this later, I've since figured out a better way.

    Got a few ribs and stringers in. Getting a feel for size.

    We got the deck strips tied in place and turned over. The keel is one piece of boo split, making a sandwich of the frames.

    Took the project inside to skin it. 12 oz painters canvas did the trick.

    Here we put in a split bamboo floor, which needs redone as well.

    With this next one I took what I learned and got a bit more sophisticated with the design. I wanted the first one stable for my kid, and this next one I wanted to be able to be in some waves and not tip. So, I had to loose some initial stability to make up for it on the back side.

    I also wanted to be able to lean back and rest, so I built a better cockpit combing.

    I will spare the detailed account of how this one was built but point out the differences. I learned the proper way to lash frames, used a heat gun to shape my frame stations, and I used split strips to make the stems, and lashes the stringers into them.

    Figured I'd show the stitch I used to close the ends by the stems
    Latex filled in the holes well. No leaks.

    Here I did what I call a button stitch to draw the skin tight over the frames. It's nothing special, I just grabbed the fabric on both sides, pulled it tight to the center, and did a quick stitch to keep it in place. after going the length, I came in with a proper stitch to close the deck.PicsArt_02-12-01.37.46.jpg

    It got drum tight and really strengthened the whole structure with the skin. It's really strong now.

    Here they are side by side painted and ready to float. On the orange one, I sit on a flotation cushion. Simple and comfy.

    Here is the maiden voyage of the orange one. It's a little too tipsy for me, I'm gonna need to throttle back a touch on that and make it a touch more stable. Also, I need to get rid of that ugly hump up front I had built for flot9ijcase I capsized. It catches too much wind and is unnecessary. I just stack pool noodles inside to keep it afloat IF she tips, hasn't happened yet and my son and I have paddle for many hours in these. Next summer the get overhauled.

    That's it for the pictures. My wife has a few videos of us out there, I will ask her if she can find them and post them on here. I'm planning to build a few more and my son and I are going on a river paddle/camping trip to the Atlantic intercoastal waterway in a few years after much practice.

    I can give you some stitching techniques for the next skins that will help you get good tension with less knuckle damage. I built a more than a few sof boats with #10 duck, which is about like a tarp.

    Also, whatís better than goofing with your kids on little boats you built together?

    Happy people. That's nice to see.

    I've never worked with bamboo. I understand that it is a grass and doesn't have any grain, which would make it difficult to split. Did you saw it into strips?

    Its actually quite easy to split, you could split it with a spoon if you had to.

    Here is a video link to the video my wife took, it's a Facebook live, so pardon the poor quality and chatting. It's the maiden launch of the orange one, my son however is well practiced in his, and is off like a fish in water.

    I'd be VERY happy to have those tips, though it will be summer, maybe fall, before I get the chance to rework those boats and reskin them. Also, what dimensions can you get your #10 duck in, is it 10oz, and what's your source?

    I had to order the duck. 10 Oz and #10 are VERY different. If I remember correctly, I was only able to get it up to 60Ē.

    Honestly, you might could buy some polyester cloth and cost about the same, but have a MUCH easier to sew skin, which will be lighter and actually tougher.

    There are no secrets, for me, about building boats. What all I know Iíll share. Anytime you have a spare ten minutes.

    Peace,
    Robert
