I used to ride waves on an ocean kayak frenzy until my friends forced me to be a regular surfer. I agree that it's all about the pilot of the craft, but I knew as a kayaker that you can't really turn (at the the frenzies) if a surfer is ripping down the face of a wave. I tried to stay away from line ups of surfers who weren't happy when they saw me paddling out. Fortunately in Strathmere there is always plenty of space for everybody.
As a board surfer I now I am not happy when a kayaker wants to hang in the lineup of surfers. This lady last summer kept paddling her kayak right in front of us just to say FU. So being on both sides of the fence I feel that kayakers should surf their own spot or stay on the edge of a lineup.
