I went on a few charters in Mexico where they used the boat to set the hook, it's a pretty common practice down there I guess. It sure did wake us up the first time though, the water was getting rough and we were about outta time and all of the sudden the captain floored both the diesels and we took off full speed, meanwhile the mate was running down from the flying bridge, and one of the rods was screaming. We were too lost and confused for a second to figure out what was happening, and by the time we slowed down again it was off. We got a marlin on a different boat the next day and the captain did the same thing, ever since then I've always wanted to try it for salmon, guess someone already has:-)
