Which Fins are best for which scenario?

[terryw]

Thought I would throw out a topic that I haven’t seen on this board yet to get some opinions about which fins to use for O-Boats and U-Boats where you are down in the water verses those like the Fat Cat or a pontoon boat where you are sitting out of the water for the most part.  It seems to me that the kicking motion you would use in each of these three cases would be different, therefore up-curved fins like the Force Fin may work better when you are down in the water and kicking by raising and lowering your legs rather than up out of the water in the case of the Fat Cat or pontoon where you are just bending your knee to move your lower leg forward and back.  I’d like to hear some thoughts on the topic.   Terry Warwick Carnation, WA
