I remember 1 incident a few years back at an unnamed launch - where a couple had returned from fishing and the guy running his boat dropped his presumably wife off to get the truck and trailer and back it up to meet the boat (This was before everyone had a camera on their phones and access to Facebook within 20 minutes).
She was obviously a little overwhelmed being on display and a bit flustered and was panicking a bit. So she was over correcting while backing up so some of the rest of the onlookers like myself were offering some verbal support (i.e. that's ok just turn your wheel a bit to you left, etc.) but her husband decided to loose it on her instead - yelling & abusing her and swearing and calling her names (f-ing stupid, etc.) from the safety of the boat.
Well... that went over like a lead balloon with the rest of us - who were (or i was anyways) thinking of clocking the guy - but by that time had the boat up behind the truck and trying to jump onboard the truck to take control. At 1 time he almost fell into the water - and myself and the others offered up a collective cheer of "Ya @sshole - I hope you go in, etc.".
Long story short - after 20-30 minutes of watching this debacle - he finally got the boat in on the trailer with only his pants wet and squealed his tires getting otta there. I sure hope that trip ended-up in a divorce for the lady's sake. Nobody deserves that kind of abuse from anyone. Maybe he's the same guy in the minivan. I sure hope so.
Also had someone "remove/steal" one of those wrenched-in plugs for a sealed self-bailing hull on me before when I wasn't around - and I forgot to check since I never removed that plug when the boat was winterized - and launched w/o checking. I won't make that mistake again, neither. I always double check just before launch - and have a bail-out pump onboard as well - for myself and anyone else that needs it.
