FYI, here's a map of the 50 fathom line for rockfishing. Remember, the depth limit for fishing isn't the actual depth, it is the shoreward side of a line of waypoints listed in the Federal Register. My points here are pretty close but not dead on. If you'd like to make your own cheat sheet, here's the list for Point Arena to Pigeon Point:
