Chartered in 2020 with Dream Yacht who set up a temporary base during Covid. Brought a few boats over from the Bahamas that were sitting idle. Boats were not in great shape, and they've since closed it. This was before the Moorings established an operation. They just have a partnership with Florida Yacht Charters. Might as well go direct to them unless you get extra discounts by booking through the Moorings. Believe the other option is Calypso but I'm less familiar.
We booked a last minute trip in August - definitely don't do that unless you have AC. Very hot, light winds.
Ran out to the Dry Tortugas and back - loved the park. Had to do a lot of motoring, however, to and from. Fishing along the way was great, get down to the drop if you have time as RickG mentioned.
Depending on the time of year, it can be quite frustrating dodging lobster trap buoys. The farther south your route towards the drop, the better.
