On St. Thomas, Independent and
Compass Point are in a
hurricane hole. Our 6' 5"
keel kissed the mud at low tide in the channel. For a 40'
monohull, we paid $660 per month ++
electric and
water at Independent in 2016. There are a couple of other options near there, but check the depths. We are in Frenchtown Marina now for $550 per month ++, but will haul at Independent August-October.
Depth is no problem there. Prices go up from there at AYH, Compass Point and Yacht Haven Grande.
Puerto Rico is close by. Check out Puerto Del Rey and the Fajardo
marinas.
