The first time I tried a kayak, I definitely wanted a rudder. Now I'm not so sure. They drag, they foul tow lines, and they cost a bit of money. But the worst thing is the fact that the foot rests move when you try to knee-hang. I learned to lean out of turns, but the moving footrest forces the rudder to counter this motion.
I've never used a skeg, but it seems that it would help in cross winds (which is the only place I use a rudder anymore). With the cleaner aft deck and solid footrests, it would seem a great thing. Is there such a thing as a skeg in a plastic boat?
Yes, I know what I'm missing by using plastic, but you should see the nasty rocks at my put-in. Must I go fiberglass?
