I would second the recommend Kevin at Light House Point. We are at Light House point now and like the marina. When we bought our Great Harbour 47 we moved it ourselves up from Punta Gorda Florida. The trip north taught us alot about the boat and was a great memory to start our relationship with the boat.
We are still working so the trip was done in three segments - a week to move from Punta Gorda to Melbourne FLA, then we worked a month, moved it from Melbourne to Beaufort, NC, came home and worked a few more weeks and then the final run from Beaufort to Baltimore MD.
