In reference to how much training you need for a boat, About 3 years ago, two friends and I splashed out a bit of cash on a 240hp speedboat, with a vne (or whatever boats have) of about 45kts. The sum total of our experience before we were set loose on the river tyne. We had once driven a putput boat on lake Windermere. So I would dispute strongly that you need any experience at all to drive a power boat.
