I like to look at sailboats. They fill my mind with adventure and fantasy. When I look at a boat through binoculars, I am not looking as a personal invasion. I am just taking in the image (and the story my mind adds to it). But I am in fact looking at aomeone’s house. If someone was outside my house looking at it with binoculars, i’d Be a little unnerved. Is it different with boat owners? Do they expect fellow boat owners to check them over at a distance? When kayaking into a harbor with anchored boats, I might paddle by close enough to appreciate the design, but I wouldn’t intrude except to wave if someone were on deck. So what is the expected courtesy. Is boat boat gazing with a glass just too snoopy? I’m assuming what I can see from the dock/warf without magnification is fine.
