Forgot to discuss the downsides of using planks. They would tend to split lengthways along the grain (due to swelling, shrinking, cupping, etc.) unless you screw good strong cleats to the undersides. In some cases there isn''t good room for the cleats, and they can add weight. In newer boats with wider cabin soles, plywood is stronger for the span required, and cheaper.
