I don't see how this would work.
1. South Beach is not known for it's great parking. South Beach and the beaches to the north and south would not support the crowds. (To many High rise Condos)
2. The Port of Miami might be able to take Small-Med size NAVY ships but it's to shallow for Carriers and LST
/LSD's (Even after being dredged).
So if it were to happen, the "Sea" part would/should most likely be droped. Being that the rest of the Sea part consits of a few Power boats, the Florida Marine Patrol, and some Seadoo demos.
