Seems like a good time for a kayak fisherman to jump in. I fish otter point quite a bit when weather permits, the only thing that stops me is wind. I do fish in the fog, and worry about just this scenario, someone coming close to shore inside the pack going fast. I see it happen a lot when there is no fog and I don't hesitate to flip you the bird if I see it happening. The latest one was the commie crab boat on wed. ripped right past me, big wake, lots of noise. Had to deviate my tack so as not to take in in the lap.
Can you see a kayak on radar?
