Divers have been inspecting a capsized catamaran just off shore from the oldest dry dock in Plymouth at Mutton Cove. Washfords are leading the salvage operation. In the sixties and seventies multihulls became more popular in the quest to go faster on the water. Catamarans were built to exact and innovative designs and used synthetic and lighter, stronger materials. Competitive racing and catamaran challenges attempted to mirror the famous America's Cup Catamarans.
