Brunswick Landing is very good, but is best for in-water storage
as said by Vasco. St. Mary's Boat Services yard is good too, and best for hauled on the hard. If you're thinking closer to Savannah, Sail Harbor is a potentially good choice, as is Hinckley Yacht Services and both have in-water available too - although space is limited at these facilities; both of these yards have come under new management and are full with repair projects.
And for those who don't know, Steve is now the owner and GM at Sail Harbor. Dick Long has formally and officially retired.
