    That boa above is traditionally made, only the deck is plywood.
    Your chined hull is not really suited for strip planking. If you want a deep V hull in strip it should look like an ellipse. If you want it chined plywood is better. Or you do cold molding (basicly making your own plywood) by diagonally planking between the chines and having the layers glued with epoxy.

    Hi Rumars,
    Yes in the southern part of Ghana where most men are into fishing, they all use the traditional method which I think it is easy to maintain but may be too heavy I think. Canoe fishermen they are call IT

    I try to avoid the chine thing as much as possible because I read in some google search that show how it can flaw the boat if not done well.
    I cut some few panel that I later decided not to use

    Are we to understand those individual 'facets' in the multi-chine hull, are to be planked by a single plank, over the entire width of it ?

    I think the OP is showing us what he built and doesn't wish to pursue?

    But this does add confusion.

    The way to go forward would be with an ellipse or roundish shape cut from plywood instead of the facets or multichine.

    personally, as a guy building a multichine boat, I have no problem with them..

    Somarine, what do you not like about multi chine boats?
    They do have a lot of advantages.
    And the chines are not glaringly obvious on the Woods designs like Fallguy's Skoota.
    Please do at least find a boat online that you like, download the study plans (you might have to pay a small fee for this) and then decide if you still want to design a boat yourself - there is a LOT of work involved.
    And is it really worthwhile spending perhaps US$100,000+ on materials (and labour if you have to pay people to help you) to build a design that is not already proven?

    Bajansailor, while I agree with you about him buying plans, I think you are wrong about the total cost. The most expensive thing he will have to buy is the motor. Anything else is cheap and I fully expect that even a used outboard is going to double the value of the boat. I know this is hard to believe but materials and labour are incredibly cheap by our standards. Just check what chinese epoxy and fiberglass cost. I expect the wood to be even cheaper since it is local. Of course what is cheap for us is expensive if you earn your money there, and the total sum will be a major investment for the OP. One more reason to buy plans, but I also understand that the plans cost may seem excessive when you compare it to what you can buy locally for that amount of money.
    Now if the OP would give us a SOR maybe we can find some cheaper plans for him.
