Is it possible to add a third tracking fin onto an 04 Centurion Cyclone.

there is no way to add a xtra fin

Where there is a will there is a way. <BR> <BR>Why do you want to add a fin? <BR> <BR>It won't be easy, and if you mess it up you could sink your boat (imagin a fin sized hole in the bottom). You can't just drill two bolt holes through the bottom and bolt the fin up, it needs to seat against a well reinforced portion of the bottom. I would expect that you would need to cut out a fairly oversized section and glass in a sturdy solid piece. <BR> <BR>I haven't paid attention to my current boat, but the previous two boats, which were direct drives, the mounts for the tracking fins were tied into the engine mount and ski pole mount. Big metal plates fastened down to the hull. <BR> <BR>I just can't imagin what benefit you would get for all that work.

Tracking fins were mainly for the slalom skiers, who could pull the boat side to side when they cut. The center mounted pylon and tracking fins were made to counter those forces and keep the boat going in a straight line, particularly going through a course. <BR>Rod is right, it would be a lot of work, and somehow secured to something significant. Why do you want to do it?
