My fiend had a behemoth of a boat that he got cheap (aka paid money for someone else’s problem), and it seemed every time we took it out it would lose one engine. Trying to get that thing back into its slip on one engine was a nightmare, we’d be standing at the railing waiting to deflect it from whatever it was it was going to plow into.
A few years ago I rented a motorboat on lake sebago in Maine with some friends. We hit a rock and I just happened to be at the wheel. We were following the markers to the T so I don’t know what happened. Thankfully the rental place only charged us their insurance deductible. Of course they assumed we were drunk or something, so we had to be the laughing stock of the marina.
