70"
I`v used rhino3d for making the design, then by using the unroll tool all surfaces were flattened. Then it was all a matter of printing the flattened sections, bottom, side, deck, etc, to the size I wanted the boat to be , and cutting plywood on these patterns. Then joining all together.
I already bought a stock Zenoah G260 (I think with a good pipe it makes 4 hp). I`m not a speed freak but I`think the engine will be enough.
now I already finished the mold and the hull however, I had a little problems when removing the hull from the mold, it was to hard. after 4 day of hard work I managed to remove it with a little damage to the hull.(maybe I used the wrong wax)
I`m going to use resin to bond the deck with the hull
I`m going to take some other pics of the work.
