Gil, welcome to Tampa Bay...
We'll assume you are dismissing the Clearwater area, and the waters north of there become too shallow for your draft (Tarpon Springs and N...). Since you say you'll be relocating permanently to "Tampa" I'm not sure if you'll be working in Tampa, living there, both...or are just using it as a generic term. There are marinas on the Tampa side near the airport but it isn't a great place to locate a sailboat (shallower water, raised bridge segments you'd need to get under). The yacht club on Davis Is., located in a very tony residential area right outside downtown Tampa, is popular for racing but you haven't mentioned that interest, nor is dockage likely available.Still on the Tampa side, this takes you further S to Ruskin (just N of Port Manatee, if you have a map)...or across to St. Pete's downtown area. One location or the other would make more sense depending on where you'll be living. Ruskin's marinas are inside a dredged basin and, altho' not immune from tidal and wind effects of any major storm, this is the most protected dockage in Tampa Bay - and even here, the dock pilings can become killers, as is true of the cheek to jowl boats. Anchoring in a protected basin (e.g. up a long channel or basin in a residential area, which is possible) is about your only 'fighting chance' in a storm. I'd suggest you give up the hope of your boat escaping a major storm and instead exercise all reasonable prevention (the marinas will have guidelines) and increase the hull value on your policy.Re: the downtown St. Pete area, The Harborage is a bit remote from the immediate downtown area (where the park concerts, sailboat show, street parties, all but one museum, etc. are located) but it's the nicest of the St. Pete downtown marinas re: amentities, and it does have floating docks. The main marina is the SP Muncipal Marina (see info at www.stpete.org) which is again going thru an improvement program re: the docks. The muni marina offers basic, safe, clean dockage and facilities (no pool; tons of eateries nearby, as is a small WM Express store and another chandelry) and so it is ideally located and also cheaper than the Harborage or the Vinoy Marina (at the base of the restored Vinoy Hotel just a bit further N and much pricier). But all 3 (Harborage, Muni, Vinoy) are pleasing places and offer differing amenity & service levels for different costs).We've docked twice at the Muni Marina, once in each main basin (N and S), both as liveaboard and non-liveaboard customers. We've found the privacy vs. central location and basic amenities for lower cost to be unbeatable if seeking downtown dockage. Call the marina and arrange to get on their waiting list *right now*, even if you don't end up relocating there. The list for your size boat isn't two years worth (it is for a 'B' slip which we would need) but it's long enough to make the $25 risk of not accepting an offered slip worth the investment, IMO.If you look at dockage at the S end of the Pinellas penninsula, watch out for wake & surge; the docks down in the Tiere Verde and nearby areas seem to lack much protection.Good luck!Jack
