    The engine, if you get one, is the expensive part. I found the 9.9 Honda for $2,000 and replaced it with a 20 Honda under $4,000. Do comparitive pricing. The same 9.9 in central Florida ranged from 2k up to 3k depending on the dealer.

    I don't think I'll need any engine! I want to use only sails and paddles, but thanks for the tip :)

    The maple you sell to the furniture makers for money, wich you then spend on fasteners, paint, tools, and other things that don't grow in the woods by themself.
    The oak can be used for the centerline timbers and frames. Cedar and pine can be used for planking. Fir can make the entire boat asuming it is douglas fir.

    Ian Oughtred has the option for "traditional planking" on all of his designs. You just have to specify this when ordering plans, otherwise you get the glued ply ones. I understand one can also deal with the designer himself for plans.
    Unfortunately I don't know of any 10m "viking" boat plans. Maybe the folks at the woodenboat forum can help you.

    NativeTech: Native American Birchbark Canoes http://nativetech.org/brchbark/canoe.htm#:~:text=Birchbark%20canoes%20are%20most%20commonly%20associated%20with%20Native,incredible%20size%20to%20carry%20an%20amazing%2050%20paddlers.

    Any big (around,, thick) birch trees in your area?

    You want the bark as a long sheet width equal to trunks circumference.
    I believe it kills the tree, since the thin layer tissue under the bark is what lives.
    Birch wood makes pretty veneer and great fire wood,

    Tradition https://canoe.csumc.wisc.edu/LdFCanoe_subpage_Tradition.html

    Why consider a birchbark canoe as a first boat build? Finances. With luck and a silver tongue, and your own sweat, you might obtain the building materials free, or at small cost.
    If it finishes up as crooked as a snake and unseaworthy as a folded paper boat, you aren't watching thousands of dollars go up in smoke when you torch it!

    some small outboard are identical engines from 9 to 15 hp, just different heads and carburetors. Unfortunately, I don't remenber which makers do this trick.

    Here the trick is used on larger hp engines. Maybe the same mfg do it on the smaller models. some searching should find answers on net. This came up fast.

    and this! They say don't do it, though it CAN be done!

    I think the goal is a quiet ride so the natural environs can be appreciated without disturbing the denizens. Paddle or sail as previously stated would be preferable.

    I like the idea of selling maple to buy other things.

    If I have oak, I have very few of them, so is there any alternative?
    I do have a lot of cedar, can the entire boat be in cedar?
    The type of fir I have is balsam fir

    What's the difference between traditionnal planking and glued ply ones? is it only the method of building? how do you assemble a boat with the traditionnal planking method?

    Thanks a lot for the tips!

    I really like the idea! I do not know if I have a big enough birch tree to do that, but I'll try to find one tonight! It could be a great start!

    Thanks for the tip!

    You don't need much oak for a small boat. A straight piece for the keel, some curved ones for stem, stern and knees, and straight green pieces for the ribs. It needs to be white oak, red oak is not rot resistant. If you don't have oak, you sell maple or cedar and buy some. Cedar and pine are to weak and brittle for this job. Balsam fir is only good for spars (mast, boom, etc.). Traditional boats are held together by nails, rivets and screws. I linked one video, but the channel has much more. The glued methods produce stronger, stiffer and lighter boats.

    The Lake Scows of Lake Minnetonka and White Bear Lake, Minnesota, built by Johnson's boat Works, were built of white cedar.before the fiberglass models. There were many sizes. M scows, C scows.One of the kargest was the E Scow. I use to own one. Pictured below.
    ecow.jpeg E scow.jpeg

    They are very fast, with enormous rigs, and complicated to sail. Hull is 26 ft long, mast is 32 ft long. Big sails!You can see the boom is long and sticks past the transom. Requires running backstays, Twin rudders and twin bilge boards also. Lots of strings to pull!

    Certainly don't recommend building one!
    White cedar is a good, strong, light weight, boat building wood., is my point.

    If you can get the white cedar big enough; it will work in a sheathed boat quite nicely. Get the boards rough sawn at about one inch plus. A bandsaw mill is really nice.

    Read the book by Gil Gilpatrick on Strip Canoes. It'll be a go button.

    Interesting, I don't know where I could sell my maple tho, but I'll look into that! When we buy a plan, we have a list of material at the beginning I guess?
