Charleston local guide
Charleston is saltwater boating: the harbor where the Ashley and Cooper rivers meet, the Intracoastal Waterway behind the barrier islands, and tidal creeks such as Shem Creek in Mount Pleasant. Storage is spread around the edges of that water rather than downtown. 7 Storage has dedicated boat and RV lots in Mount Pleasant and Summerville, Maybank Boat & RV Storage is on Johns Island toward Kiawah and Seabrook, and Twin Oaks sits on US 17 (Savannah Highway) in Ravenel.
Salt is the storage issue here. A boat that comes out of the harbor needs a freshwater rinse and engine flush, which is why an on-site wash station matters; Twin Oaks has one, along with free compressed air for trailer tires, on a gated lot of three to four acres. The family-run yard has served Charleston since 2001 and keeps office hours of 8 to 5 on weekdays and 8 to 2 on Saturdays. 7 Storage stores only boats and RVs and runs everything online, from the lease to payment, with a personal gate code for each tenant. Maybank offers both indoor and outdoor spaces with 24/7 access.
Rental boats are easy to find on the water itself. Shem Creek Marina, off Coleman Boulevard in Mount Pleasant, rents pontoons, center consoles and deck boats by the half or full day and has a fuel dock. Isle of Palms Marina rents pontoons and center consoles in four- and eight-hour blocks, and Seabreeze Marina on the Charleston peninsula rents center consoles and kayaks.
Boating in South Carolina: since August 18, 2023, anyone born after July 1, 2007 must pass an approved boater education course before operating a boat or personal watercraft with a motor of 10 horsepower or more. Renters in that age group can instead carry a rental safety certificate issued in their name. The dump stations mapped below are at James Island County Park.
Across our three Charleston guides we currently list 8 storage facilities, 2 RV dump stations, 7 named boat launches and 4 boat rental businesses. Storage details come from each facility’s own website and the date we checked it. Dump stations and ramps come from OpenStreetMap. We never add prices, ratings or availability that a source does not publish.
