Having a 1648 Weldbilt hull getting mods for a jet. The shop cautioned against using under-floor foam sheets because "they eventually absorb water." Is there a better foam sheet made for this application that is completely water proof?
Decided to use 1/2 or 3/8 plywood with rib spacer blocks underside. That worked great on a previous hull, Lowe 1648. Floor was in two pieced fit to sides with finger holes on outer side for raising them if the hull needed repair, which it did twice.
The ribs are much wider on the Weldbuilt so there shouldn't be any sluff.
