The anchorage is pretty open, but protected from the tradewinds. It might be interesting there during a cold front when the westerly winds come through. A swell can easily get through/around the couple of reefs
on the outside of the anchorage.
Many boats spend a lot of time there, so the anchorage isn't real bad.
Be aware that this town and beach are party central Thursday-Sunday. If you haven't heard Puerto Ricans partying yet, you may be shocked. The music
is so loud you will not be able to sleep. Even with earplugs. The hull
of your boat will be pounding like a bass drum from being assaulted with unbelievable levels of music
But don't worry too much, because it all winds down around 3-4am and doesn't start again until sunset - so you have plenty of time to sleep then.
Unless jet skis using your boat as a part of a slalom course bothers you.
The "town" itself is solely dedicated to catering to the partiers. 90% of the "stores" are bars and the rest souvenir shops. There are a couple of restaurants. The town is zipped up tight Sunday-Wednesday. A restaurant or two may be open, but everything else is shuttered up and locked down.
If you are arriving to PR, don't check into PR through Boqueron. That used to be standard practice (take a taxis to Mayaguez), but in the past few years, customs
has been causing lots of problems and fining people. Check for more current
info on this because these things change frequently.
