Most of the time, I don't really mind a wet butt or shoes, if it rained recently. Sometimes, however, it's downright annoying.
Shoes? Can't recall the last time I wore such things on my boat. Flip flops get kicked off on the dock and are stowed until I step onto land again. Wet butt? Yea, that's happened a time or two. Guess I could wipe down the seat in about 10 seconds if I really cared. Most of the time I'm already wearing swim shorts anyway.
What would be really annoying is being crowded together with a whole bunch of other boats and people. I like to socialize with other folks in the marina, but I also like to "go home" when I'm ready to have some peace and quiet.
