A word of caution. These hulls can achieve speeds of 30Kn or more with either inboard or outboard power. All At Sea spoke with Hatfield about trends in power cat design and build and how design features are making for greater fuel efficiency.

Innovative boat designs that genuinely enhance the boating experience are rare. The most important catamaran design hull shape factor is the Prismatic Coefficient Cp. Instinctively you might think that fine ends would be faster as they would cut through the water better.
