Yesterday I was sailing around the pier. Naturally I don't want to get in fishing lines and don't want a fishing kiteboarding clash for access. I was at least 1000 feet from the end of the pier and my hydrofoil caught long fishing lines. Had no idea they could go so far out. When trying to untangle the line the fisherman kept reeling in, hoping for a big fish. Then I found there were at least 3 fishing lines very close to me. Too dangerous so I abandondened the board and carefully body dragged out of the lines and then to shore.
Luckily everything ended well. Apparently when going for shark they paddle the bait in a kayak. The lines can stay very near the surface. There is a heavy weight to keep the bait down, sometimes a grappling hook. It would not be easy to swim fouled in that. The fisherman was quite disappointed with his catch, but I got the foil back.
