If you take your time and keep the plate cool there is no reason the boat shouldn't come out looking pretty fair. The side plates are the biggest part of the boat and they weigh about 70kg each. Working smart, 2 people can wrap them, with 3 it will be easy. Where are you based? Plate Alloy's boat building course (while it might start off a bit easy if you can weld) is well worth the time and investment. Its a truism that after building your first boat you're ready to start building your first boat. So if someone else can own that first one you're ahead of the game.
