Summer in the Bahamas is beautiful. Just check out your hurricane holes, or haulout possibilities. There are umpteen of them to choose from.
As to heat, we ran a fan occasionally, but other than that it was very tolerable. Aside from lobster being illegal, the snorkeling and diving
is superb, as the water is very warm; you can stay in for hours without a wetsuit.
Very few boats out there with you; if you like that, it's good. Georgetown
, which at this date has 133 boats in the harbor, and will build to 300, give or take (well down from peak years with as many as 500) later this spring, may have a dozen altogether. Marsh Harbour, a crowded anchorage in season (along with the several marinas
and the Moorings/Sunsail operation, along with the BoyScout program), had a half-dozen tightly kniit cruisers there during this last season, in part due only to a few of us having mechanical issues preventing moving elsewhere. Other less populated places will have even fewer.
Running to FL, IMHO, is a non-starter. If the weather is bad enough for a hurricane, getting a good window to FL is chancy at best, and then you have to find a good place to hide once you're there. WAAY too many choices in the Bahamas to cut and run, sez I.
Many places have hurricane proven moorings; nobody's there, so there are many available to choose from. Anchoring
is another subject entirely, and up to you as to what you do about it. If you're skinny enough, you might be able to go up some mangroves, but it's pretty shallow, and most of the ones I've visited are pretty narrow as well. Best bet is to get into a 360* coverage location, whether moored or not, of which there are also many.
Back to the experience, stay offshore
to avoid the bugs; it's easy, most places, as there's no place which doesn't have shallows nearby (say, 20' or less) where you can anchor, and breezes are better on open water as well.
We're coming back, again, this year (well, we're here, but we're leaving, for a minor refit
, then a wedding and a birth (different women!) before returning...
Skip, lying George Town, on the way to Conception for a few days before returning, before then heading to the Jumentos
