Sunset Bay Marina is right around the corner and is much nicer. They have far more amenities then Loggerhead. I have several friends at Loggerhead and they all say the same thing:
1) The condo owners don't really want the boaters
2) The walk out to the boat is long (wasn't too bad but on the upper end for a marina that size)
3) The "outside" docks are very rolly. We were on a friends 63' Hatteras one dock
in and they were rolling, but better.
I don't recall
any moorings but Sunset has them.
We stayed in Jensen Beach at the Nettles Island marina for three months and it was cheaper, but no real amenities and we didn't think it was worth the $100 less vs. Sunset. We won't go back there for a long stay.
The Fort Pierce Marina is very nice. Good amenities, nice walk, fun restaurants, and of course, right by the inlet.
