Portman,
Yes and that lightness will have a profound effect on performance re speed and power needed to drive. A light plywood OB boat like the Bryant 21' OB cruiser of the 50s did fine w planing performance having two 35hp Johnson engines. Those two engines would'nt push a contempoary plastic boat .... too heavy.
Those that require speed should shun trawlers and embrace cruisers.
