The Blufin is a new boat and I have found the prototype very fun and comforable to paddle!!!
It has a comfortable cockpit that provides good bracing support: hips, thighs etc. The rear of the cockpit is 9-1/2" high which is low enough for easy rolling.
It is a multi panel/multi chine hull, which gives a nicely contoured shape with a smooth, sharp entry, nearly eliptical mid-section and slick stern. It has good Initial stablility and a comforable and predictable secondary stablilty for leans and Eskimo Rolls. It is fast and responsive and gives a very smooth ride.
