it is probably not a regulation but it is smart to have one. i have had bass boats since 1982 and have not need one to paddle back to the launch with. but i have used one several times to push away from the bank if you drift up to close to use the trolling motor. my favorite use is to whack snakes with it when they try to climb into the boat. i would not want to go to the lake with out one. they dont cost that much and they are very cheap insurance to keep you from being stranded. but thats just my opinion.
