Harbourtown Marina in Cape Canaveral on Merritt Island is the #1 place to store a
boat during the hurricane season and as a result is normally totally full and has a waiting list that can be very long. Titusville Marina is another option. But generally all the
marinas in
Florida are overfull.
Marinas that are considerable distance inland or away from the coastline are your best bets to find space. There are two good marinas up on the St. Johns River about 20 nm inland from the
Jacksonville Inlet - Reynolds Park Yacht Center and Green Cove Springs
Marine. They are both up the St. Johns as far as you can go before encountering the 45ft bridge at Red Bay Point.
