I wish everyone was as considerate as you.I get a little irritated with the nonsense that goes down at the launch but I would have no problem with somebody who doesn't have anyone to help them taking a little longer or tying up on the dock etc.That's reasonable.
Personally I just avoid weekends when I am alone or with someone who isn't able to help me much.I also like to launch extra early so I can do my thing out there and then pull out before the rest of crowd decides to call it a day.Good luck.
