You can set up as a two + 1 like Haydn but the fin box’s are usually in the wrong place to run as a twin.
Quad are good for generating speed, making it good in small waves, the quad fins also allow for quick, sharp turns, similar to a twin but with added control. Does have more drag than a twin because of the extra fins.

I was starting to find hpsb a struggle these days. Now I’m older ( 60’s) stiffer and of course slower means that they only work for me on odd occasions. Does not help that I’m on the most of the time gutless waves of the south coast. This is the fish I’m currently enjoying. Would love to hear your opinion on it.
