You may want to check out Jean St. Shipyard, they have a bad hill to get into but, I think he is reasonable on the pricing. The other option would be Interbay moorings if close proximity to Tampa is needed. Salt
Creek, last time I checked was pretty pricey, but the economy may have changed that.
It is pretty slim picking for operating yards in the area.
Your other option would be to research
some of the closed yards. The dockominium craze is pretty much on standby. You may be able to work a good deal at one of them.
I wound up leasing a piece of land, putting up a temp shelter and moving the boat to it (48' ketch).
