In the drawing portion of the shape the ships are all canoe hull with the base hull colour being pointed at both ends.
it would be nice to have a scroll to select the type of stern as
Canoe (current) Narrow transom (small flat at rear) Wide transom (wide flat at rear)
The flats being more significant in the carrier or float plane era.
Possibly there might be handling affects vs speed for these but mostly I am currently asking to include shape options for the base hull. One can cover the deck with drawing but that is currently always grey not the base hull color.
