Yesterday the wind in the afternoon got up to 20kn, only 4 of us went out, Avital, Yotam, Yair and myself. We went out against the wind for about an hour. The wind waves were about 1 to 1.5m high and the paddling was really a lot of fun, bouncing over the waves and feeling the spray blown around.
Avital and I were paddling with Greenland paddles and I have to admit, it really was easy going, we both felt no adverse effect of the wind on our paddles
A good sprayskirt is essential in these conditions, otherwise your kayak gets full of water and then you have to raft together and pump it all out.
