Here's one for you...........if I catch a ling cod at 120 feet, the current is running strong, and in the process of dragging him up, the boat drifts off the edge of the cliff that I had been fishing along, and by the time I get the fish alongside I'm in 300 ft of water, must I release the fish?

I can think of a number of places that fit that description to a tee, and there would be no way to hold the boat over the 120 foot plateau and drag ol' bucket mouth against the current, believe me.
