Re: how long does it take you leave?
We leave when the wife is ready, she stows the gear puts out the cushions. I check the rigging open the seacocks, warm up the engine, remove all dock lines but two. Normally this take 15-20 minutes. When we get back it's everything in reverse, with a quick wash down included, 30 minutes.
If it's social hour add 3-4 hours.
