A composite in boat building would be things like;

A deck, fiberglass both sides with a core.

A "strip built" canoe or boat hull that is glassed in and out is a composite.

Also ,a wood boat with fiberglass on the outside hull may be passed off as a composite to the uninformed buyer.

Composites are used extensively in many things from aerospace to things in the home. Sometimes lamination's are confused with composites although You could have both in one. Plywood with boards above and below would be a composite, Some composites (and lamination's) are made with thousands of pounds of pressure to bond the layers. Simple luan plywood doors in a house are a composite; thin plywood with a cardboard honeycomb.

The big fear of cored construction in boats is the possibility of the core getting wet and rotting. Cored construction is strong because it is a composite. Racing boats are typically cored construction. Some manufacturers have also built production boats with cored hulls
