I happened to see an old rowing skiff upside down by the river, that was made of wood. The bottom was full-rounded, semi-circular in section. I don't believe it was plywood that could be bent so hard without cracking.
I was struck also by the resemblance that Venetian racing gondolas bear with other skiffs. No plywood in either type of boats, of course.
Though it is strange that apparently nobody builds out of covering panels that could be bent to shape.
Hold your flames a second, gents: I admit round-bottomed skiffs are unsteady and require a skeg or a rudder. That's another question, recently debated on the design board.
Couldn't we "hog" or flatten such a round-shaped bottom by the way?
I admit it would bend along wrong lines at times, that more stringers would be needed...though I did not see many on those skiffs, rather bulkheads like on our yaks.
Ole Man River He Must Know Something.
Did somebody try this?
