This Summer a lot of people want to see what Quads are all about. The big plus with a Quad is the extra speed, but more so the areas of a wave where a Thruster will slow down, a Quad set-up will maintain it’s speed. I feel a Thruster is a much better all round design, particularly in tight pocket style beachies, with Quads coming into there own in barrels and down-the-line waves. But there is still a lot of work to be done with Quads and if surfing is to progress, it has to be done with more speed. I see Quads playing a major part in this development.
What I’m now doing with my Quads is moving the rear fins further in and slightly back, which is maintaining the speed of a Quad but giving the board more of a Thruster feel through rail to rail transitions.
Fin size plays a key role in the all round set-up of a Quad. Having a similar template shape front and back, with the rear fin size being ¼” to ½” smaller, is effective. Increase the rear fin size, your board will be stiffer, decrease and the board will be looser.
Happy Surfing. Webby
