Abstract
An integrally moulded plastic boat hull structure is provided with a plurality of threaded inserts for securing associated boat components. Each of the threaded inserts is moulded into the boat hull structure through an intermediate insert which reinforces the hull and directs the localized forces away from the threaded insert to an enlarged boat hull region proximate the threaded insert. Where the boat hull is formed of low density polyethylene, the intermediate reinforcement member will be formed of a higher density polyethylene, to provide both a structural and molecular bond in the moulded hull. By reinforcing the location of the threaded insert and spreading its lead over a greater region, a highly localized stress point is avoided.
