29' Warren Mutihull Designs Warren 27

Warren27 Trimaran

The Warren27 is a go-fast day-sailor designed for a crew of one to three. She is a well-focused design on the parameter of performance and has no accommodations, as in zero, that is no cockpit or cabin. The crew sits on wing-seats over the windward ama, after all this is where your weight is needed, where the view is the best, and it's the driest place on the boat. The three long skinny hulls are interconnected with two crossbeams, or akas, which are elliptical in section. Since she is very light, she needs to be wide to develop enough righting moment. This design is practically square at 27 feet wide. The amas develop 250% of the full design displacement, are 28 feet long and have their center of buoyancy forward to develop large amounts of diagonal stability. Despite her extreme performance, she is one of the easiest boats to sail. Even a novice can tack her without getting into irons, jib up or down. I always sailed her on and off the mooring in a crowded harbor.

This boat sits on a trailer and demounts using a crew of three. Each component is removable with a few nuts and bolts and is placed on the trailer for a width of 8 feet.

This boat was built using Western Red Cedar strip plank with fiberglass skins on the hulls and carbon fiber skins on the akas (crossbeams) and mast, which is a rotating wing mast 44 ft by 12.
