Well, it got back above 30 degrees today so I was in the shop laying out the notches for the chine. Still pluggin' away! Next is to cut the notches out using the bandsaw, backsaw, or some combination of both. Jeff

Greeting everyone,
I just received my Huck Finn plans today and am very excited to get started. I plan on doing the 12 ft version modding it to accept a 9.9 hp motor. I am seeing quite a few smaller pontoons on the web and around . I want a smaller type boat that can easly be converted to electric or gas and be pulled with a small truck or car to the many lakes in my area. I also am getting an aluminum 20 ft pontoon for more family stuff. So Ill have 2 boats ! Anyway got a question to Grandchillin. you stated you did not use Douglas fir, What wood did you use? Also since you are way ahead of me , I also plan to make my 12 fter a tritoon. Any advice you can give? I'll be following this thread closely for tips and advice. Look forward to chatting with you folks.

I used 2 x 10 southern yellow pine. Cutting the sheers and chines from the edges. Here is a thread about it. http://www.glen-l.com/phpBB2/viewtopic.php?f=4&t=8681
Since you are building a tritoon, use the same building form for all three and make sure your bulkheads are spaced the same so your deck framing will line up. :shock: :roll: :oops:
Here is the link to the thread on my build. Good luck and let me know if I can be of any help.

Grand,
What kind of plywood did you use? It sure is hard to find 1/4 in marine grade. I can get exterior grade at Lowes. I think with a little extra tlc I can make that work. Instead of 1 layer of 8oz fiberglass may do 2 layers and treat the inside of the toons with copper napthinate or something like that. Also since I want to do the 12fter with modifications for 9.9 power It will probably last longer that I will.

I used Okoume. Treat the insides with something no matter what plywood you use. Price out how much an extra layer of cloth and epoxy will cost. :wink:

I decided to use Douglas Fir and Meranti plywood. I got both at Boulter Plywood out of Massachusetts. They are very pleasant to deal with and offer high quality wood. The route I took was certainly more expensive but I wanted to build the highest quality boat I could. I plan on encapsulating the interior with Poxy Shield from Glen-L. Good luck in your project.

Thanks for the info Jeff. I added them to my list of suppliers. I hope to get started on mine in the next few weeks, gathering materials as I go.

I've decided to build my Huck as a tri-toon. Eliminates the whole motor well/deflector assembly and adds buoyancy. It will be a 16 foot/20 foot configuration. See attached pic.

And then there were three. I was initially upset at the thought of having to build a third set of parts, but it is going very quickly.

While waiting for some Poxy-Shield, I did some figuring. I am going to need 10 sheets of 1/4" marine ply and 5 sheets of 3/8" marine ply. I am using merranti from Boulter plywood out of Massachusetts. Also, the cool looking multi length pontoon (see previous picture of drawing) has to be abandoned. Momma has flatly stated she wants a cabin on the boat, so it's back to three 20 foot pontoons. My plywood and lumber stash is looking small. Looking at electric planes for general use and scarfing the plywood. Going to try scarfing the chine material with a band saw today. Will have to come up with a jig to hold the board at the correct angle. Stay tuned.

Jeff

Today I practiced scarfing the chine log material. This is about 6:1 so I need to work on the angle to get it to at least 8:1. Hey, that wasn't so bad.

And here is what 8:1 looks like.
