I know what you mean about the wind on ocean. I was there last week and I just got an eskimo quick flip that wouldnt stay put. It doesn't have a tie down system either so I just tied a 2x4 onto the tow rope, tying the rope not in the middle of the board, but about 3/4s to one end. Then I just drilled an ice whole and dropped it down into it. The board then turns sideways and pulls tight against the whole. But make sure to offset where you tie it onto the board or it makes it difficult to get out, the added weight due to the offset allows one end to sink making it easy to remove. might not be the best idea, but it works
