    Default Flywood one sheet Canoe (5x10 sheet

    So, I started with the build of my first Canoe.
    It's the One Sheet Plywood Canoe designed by Flo-mo.
    Originally build at one sheet 4x8, but i'm attemping to build the bigger one at a 5x10 sheet. Length is 15 ft.
    First I build a paper model on scale:

    I would like to place two seats. Where should I place those?

    There are a lot of variables affecting seat position. A good basic trim for balancing the boat in the wind is important (and depends on the underwater shape of the boat), plus the bow paddler having enough leg space (which is affected by the width). If the intended paddlers are not the same weight you can allow for that. For quick turns on moving water, and going over waves rather then through them, it's better to have the seats nearer the centre, but for carrying camping gear a bigger space in the centre may be better - but this may not the kind of boat for those uses.

    I would either (a) look at other 15' boats with similar shape (b) make them adjustable (a bench along the side with bolt holes?) or (c) finish the boat to the extent that it's rigid and waterproof, then get two blocks of foam to sit on, paddle it and see what works.

    Hi Christian,

    interesting to see that you intend to build the 15 ft version of this one sheet design. While it should not be too difficult to build I don't think it is something that I would recommend to do.

    It lacks capacity for two (at 180 kg displacement draft will be 14 cm with only 16 cm freeboard left). If used as a solo canoe the 90 cm beam will make paddling not very pleasant.
    I don't want to talk you out of building the canoe, but I think you should know about the limitations of this design.

    Regarding seat placement Chris' advice is spot on.

    Best wishes
    Stefan

    Thanks for the answers. Capacity is not so important, its ment to take a child with me.
    But when I build the 4*8, I think the capacity would not be enough.

    @Flo-mo can I made the side panels 5cm higher for more freeboard?

    I have to use two 4*8 sheets. Then there is material left in the height

    In that case the 15 ft version will be alright.

    As reference for all kind of canoe related stuff I like the Bear Mountain Boats Study Plans Catalogue.

    Here is the seat arrangement for the Prospector Ranger 15 (https://www.bearmountainboats.com/co...spector-ranger)


    For an adult and a child in a symmetric canoe it may help to get the trim right, if they are sitting "facing backwards" so to speak, like in this photo:

    This is the panel layout for a Flywood Canoe (LOA= 468 cm, beam= 94 cm, midship depth= 33 cm) made of two plywood sheets (4 mm, 244 x 122 cm):

    Paper model is made. I think this last one is the best indeed, capacity wouls be all right.
    I'll have no holiday at the moment, so wood works have to wait.
