The opposed moulded plastic shells of a shell covered foam filled structural member suitable for boat hulls and decks are connected together by a strip of material extending between the shells and anchored in the foam filling. Flaps are provided on the connector strip overlying the periphery of the plastic shells in sealing relation therewith. The flaps can be provided on a separate strip with a tongue seated in a recess of the strip anchored in the foam. The connector strip has an outer edge portion secured in the parting line of moulds carrying the shells and providing a cavity for the foam which is severed from the connector strip after removal from the moulds.
