Trimarans can be part of SAD, but in the 60's development of the Trimaran began in earnest in west coast America by the likes of Arthur Piver and Jim Brown who found this new stuff, also known as marine plywood, to be easily crafted into durable boats that were faster than anything else sail powered on the water. The size of the tank doesn't matter much; the trimarans I sailed had mostly small tanks and didn't need fuel until needing to dock in a harbor in tight quarters.

Arthur Piver sold his plans to amateur boat builders through a company called Pi-Craft, so even Pi Super Yachts may not be that original of an idea.
