What Coastal Marinas does
Coastal Marinas, operating commercially as Quarterdeck and legally as The QuarterDeck LLC, is a Charleston, South Carolina-based operator of a portfolio of seven waterfront marinas across the Charleston metropolitan area: Seabreeze Marina, Old Village Yacht Club, Bohicket Marina & Market, St Johns Yacht Harbor, Ripley Light Yacht Club, Isle of Palms Marina, and Dolphin Cove Marina. The company operates eighteen wholly-owned subsidiaries covering marina operations, six boat club programs, three boat rental locations (listed as coming soon), on-site retail and dining venues (Island Cabana Bar & Ship Store, The Outpost at Isle of Palms Marina), charter and experiential services, and a joint venture development and management arm. Customers are predominantly direct-to-consumer and include boat owners seeking slip storage, boat club members, rental and charter guests, event hosts, and yacht club members.
The company's core technology is Q-Deck, a proprietary marina management platform delivered via branded iOS and Android mobile apps and a member login portal. Q-Deck manages the member experience across the network — dock management, fuel, ice, food, beverage, and water-toys reservations — and is positioned as the company's primary digital differentiator. The product roadmap visible on the website includes Q-Stays boutique lodging, additional boat rental locations, curated Yacht Clubs, and waterfront Weddings/Events, indicating ongoing vertical and product expansion.
The business model blends recurring subscription revenue (monthly wet-slip, dry-stack, and lift-slip rentals, plus recurring boat club memberships) with usage-based revenue (hourly/daily boat rentals, captained charters, nature excursions, dolphin tours), transactional revenue (on-site food and beverage, branded merchandise, retail at Island Cabana Bar & Ship Store and The Outpost), one-time event hosting fees, and managed-services fees from JV development and management engagements with third-party marina owners. Pricing is quote-based and not publicly disclosed. The company is structured as a private LLC with no disclosed institutional ownership, no reported funding rounds, no reported mergers or acquisitions activity, and no reported leadership changes in the source material.
