That's what I was thinking. Would never fish a dock while the owners are already on it. I've been beside a dock chasing schooling sandies when the owners came out. Exchanged greetings and eased back a little to give them space & never had any issues growing up. But don't want to teach the kids any bad habits so figured I'd get others opinions.
My aunt lived at a lake when I was a kid. We had a good brush pile under the dock & all the locals knew it. If we was fishing and a new boat was out in the cove we would invite them up to know we had a good pile underneath and let them join in.
Drift around as long as the dock is unoccupied. I wouldn't tie up, same rules as fishing slips, fish don't touch.
