I enjoy the mobility and the sense of being part of my surroundings...
If you are thinking about buying a kayak (yak) you might consider investing in a good paddle AND a spray skirt.
The paddle speaks for itself but when you find yourself in big water (standing waves from current/wind/wakes) a spray skirt will keep the water on the outside where it belongs. Mini skirts are better than nothing but a full skirt will keep the floor from turning into a wading pool...
Also, get "comfortable" BEFORE you venture out where "interesting" conditions make you wet your pants!
