94 sport fins

My local dealer (Sail and Ski) sells the fins for $75.76, part number 36718. Fin fits boats 70-97

Paul,

I'm no expert. A tracking fin, or in the case of newer CCs, 3 tracking fins will help to keep the boat from sliding to the side in turns, and will help to keep the boat in a straight line under the lateral loads of a skier or wakeboarder.

I have read articles that provided recommended placement between the bow and stearn, but don't recall the details. I seem to recall that if you get them too far forward, they can catch and cause some danger in submarining the nose.

If you decide to put a tracking fin on your boat, you will need to consider if there is sufficient structural support at the optimum installation point to handle the screws and loads.

Personally, I would not add fins to a 43 year old classic boat. I'm sure it slides and pulls a little, but that's all part of the classic look and feel of the boat. You wouldn't add fins to a Classic Gar Wood, Higgins, or Chris Craft, and I wouldn't do it with your great classic either. BKH

Yep, the fins keep the boat sliding in the turns (main benefit). I suppose it might mitigate sideways movement from the pull by skiers.

My '77 Martinique does not have fins, my '93SN does. The 77 slides in turns, the 93 does not. The slide never really bothered me because my buddy and I only ski in a straight line. Sideways movement was never a problem as we are exerting forces near the centerline of the boat (pylon). What I can tell you that fins make a huge difference when pulling tubers (my young kids). It is very dificult to get the tube outside the wake on the 77 as the boat slides and thus does not whip the tube around. Since the 93 does not slide, the tube is easily whipped outside the wake. The kids are in hog heaven. Now if I could only get them out of the tube and onto a ski or wakeboard
