foam vs plywood | boat design net a light plywood skin would seem ideal in this regard as it handles the localized compressive loads and essentially the foam inside only has to handle the shear which should be more than adequate in light structural areas especially when the core thickness is large - which is ideal for spanning a roof over the full beam of an average pleasure ...

foam core materials in the marine industry - boat design foam vs. balsa wood and honeycomb. balsa wood and more commonly plywood have been used extensively in boat construction for many years. while these materials provide excellent compression and stiffness properties for a relatively low cost they can be heavy susceptible to water absorption and will eventually rot.

balsa vs foam core - page 2 - diy yachts anyway i can't be bothered getting into a foam vs balsa debate. the simple fact is with some designs if you simply switched cores from balsa to foam and changed nothing else you could run into trouble. to switch from balsa to foam you need to make sure the different core properties don't compromise the design.

foam core versus wood core | boat design net foam core is a poor choice for a transom. that may not help your argument. use plywood for strength. use epoxy to encapsulate the plywood. properly done the transom will outlast the rest of the boat.

plywood vs foamcore-how do they compare? | boat design net foam core in the size you are talking about will not be lighter then sheathed plywood assuming the sandwich composite is engineered to a similar level of stiffness and strength. the rescue minor get's it's fuel efficiency from a unique hull shape and limited top speed. it's not a light weight boat.

benchwork: plywood foamboard or both ... i did just plywood on my layout but if i did it over again and had the money i would use foam over plywood. just foam (imo) is not sturdy enough to build on (i would think it too easy to break the foamboard when doing things on top!!!) but if you use it on top of plywood you can do so much more w/ scenery.
