I took a kayaking lesson this morning. It was FUN.
I learned about paddles, how to hold them and which side is up and paddle angles and how paddles can act as sails if it's windy.
I learned strokes: draw, sculling, J, backwards and forwards and combos, and more that I can't recall at the moment.
I learned positioning, but I can't really get to the third position. That's a lean with the water lapping the cockpit. I learned the importance of increasing the body's points of connection to the kayak. I learned rescue techniques, and the importance of paddle floats and pumps.
I heartily endorse ERBA (in Essex), for anyone interested in learning about kayaking.
