 In the period 1965 to 1970, Westermoen Hydrofoil built 6 Storm class patrol boats.The Storm class we used as the basis for the Westamaran catamaran, which was essentially a Storm-class hull divided in the middle and separated to form a much wider catamaran, suited for passenger transport.The first generation Westamaran catamarans were not as quick as the competing hydrofoils, but their capacity was larger, maintenance easier, and they were more comfortable.
