Following a tip from Yakass, I carry a stakeout pole, for just such circumstances.
Here we make and carry a Kage (Japanese kayak gaff or spear, thanks Ahnko Honu). Honed to a razor sharp chisel point +8' SS tip! I've only used it on my catch so far, but anything getting too friendly will get poked.
I've so far not had a problem with the taxman (sharks), but Aloha Dan has had his Adventure (or AI in Adventure mode) bit a couple of times. Only about 100 miles away, but everything is bigger off the Big Island.
