I have been looking at aluminum boats for the last couple years now with

anyway that a backyard builder could do this practically. Would a home
built aluminum just be built with a structural frame with pieces going in
both directions like a wood boat?



They may allso be there to help longnitudnal stability or for spray
control.

A V mounted above the water line sweeping with the lines of the hull is
almost always there for spray control. I think they even call it a spray
rail.

You can get the strenghth by rivetting or welding on
stringers made from aluminum angle.on the inside or bend some flat
stock 3 times to make a V shaped piece. that could go on the inside or
outside of the hull.

Yeah, that's basically what I figured
