I have no illusions that licensing would solve all, or any, of the major problem of people operating boats who, for one reason or another, should not. I know, I know, another -- probably incompetent -- bureaucracy to deal with. Fees and tests to deal with. No one likes this kind of thing. But is it in your best interests to be out on the water, perhaps with family and friends, and have some know-nothing scare you to death -- or worse, cause you harm -- operating a boat for which he/she has no real knowledge or experience? There should be some standard boat operators need to meet to allow them to command a vessel.
