FWIW: On Saturday just south of bay bridge - saw this first hand.
Current was outgoing at a very strong rate. Some crab pot floats out in 20 feet were being pulled just under the surface of the water.
They would shimmy and wiggle as current pushed them - then pop back up after about 30 seconds or so.
A boat about 22 feet or so was drifting for bottom fish and the lower unit got tangled in a crab pot line.
I saw the boat slowly spin around and the angler raised the engine and leaned out and cut the line free.
The float drifted out from his boat and went past my anchored boat. Add one more lost pot to total.
What could be more mundane than dying of old age or of natural causes when there is death by misadventure to be pursued ? Skip
