In order to follow etiquette, how close is too close when there's a stretch of beach with other houseboats anchored?
Yes, subjective. When people need help or it’s late in the day, and there’s nothing else nearby, I understand the situation.
But in general, I try to avoid the problem by picking a very narrow “beach” that has no possibility of neighbors, and out of line of sight to other possible beaches across the canyon. Not always possible, but that’s what I aim for. I think if you find a huge and inviting beach, you can expect neighbors. I’m thinking that includes many places in Gunsight, Padre, the sand dome in Navajo, and that great low water beach in the Escalante…
In general, I think you’re too close when you can hear your neighbor’s music (or vice versa), or are able to see the faces on the other boat. To me it’s well over 100 yards, more like a thousand feet. Or it could be closer if line of sight is blocked.
That said, I know I’m asking for it when there’s a nice beach 200 feet away… unless its a fantastic beach or it’s late in the day, I will look for other spots.
It’s trickier toward the end of side canyons that have multiple beaches and are popular. I'm guessing most people who pick such places where there are other obvious beaches nearby are more tolerant of neighbors. Not my cup of tea, but I have misanthropic tendencies at Lake Powell, so I’ll go elsewhere.
I’ve only had one truly unacceptable encounter—when a flotilla of houseboats actually took over my tent campsite on the grounds that they “needed it more than I did” (that’s an actual quote). I posted about that nightmare encounter a couple of years ago. But generally, once I get past my anti-social default Powell mode, I find most neighbors are really nice people.
I’d just rather have that encounter be a mutually acceptable circumstance… and remember that your standards of acceptability may be different than your neighbor’s…
