In the lobster industry in particular, you have a restriction to 44 feet 11 inches. Fishermen have got around that by putting a four-foot extension—some are bolted on, and some are only a platform—on the end of it, and then they make them up to 26 feet wide, so they have a whole other stability issue.
What would be the difference in allowing that boat to be 50 feet, have a normal depth of keel, and be 22 feet wide? You may have a slight ability for more capacity, but it's not going to be extreme in the lobster industry, where you're limited by traps.
