Only one that I can remember, early 90's, I was just out to family at that time and no one else. The bachelor was the son of the owner of the small business I worked for at the time. Pretty mild I guess, lots of alcohol, food, I think we played Euchre (as opposed to Poker), lesbian porn on a big screen TV (at that time, 60" projection TV's cost over $8,000!)
This bachelor had a 24ft boat and lived near a marina. Just before midnight, most of the guys had left the party. The bachelor decided to take the rest of us 4 guys on a 1/2 hr boat ride to a local bar, one of those marina bars, you dock your boat in the marina and walk to the bar. It didn't end well when we left at 2am closing time.
The boat had a single-engine inboard, typical no reverse! Docking was a pain, same with launching from the dock, we had to help maneuver out of the dock space to avoid hitting other boats, but we were all toasted, by the time we got out of the harbor, the coast guard had spotted us and pulled us over. The bachelor got ticked for drunk boating, had to stay and the 4 of us were sent home by other means. I don't remember how I got back to my car, I think by cab, I must have been sobered up by then, I didn't get home till 5-6am, Oh, his dad, the business owner, got him out of trouble. As far as crazy bachelor party stories, I gave this one an 8
very hard to maneuver this type with no reverse, add alcohol = disaster
