Marina Crazy Sister

What Marina Crazy Sister does

Marina Crazy Sister (legally Crazy Sister Marina) is a family-owned and operated marina founded in 1970 in Murrells Inlet, South Carolina, providing water-based tourism and recreation services in the Grand Strand/Myrtle Beach market. The company operates a single marina location at 4123 U.S. 17 Business, adjacent to the Murrells Inlet MarshWalk, with direct access to the inlet and Atlantic Ocean. Its core product portfolio is organized into four categories: cruises (dolphin watch, sunset, pirate adventure, eco/marsh, ghost-story, fireworks), fishing (shared head-boat trips and private charters on vessels including the 27' Reel Crazy, 36' It's a Write-Off, and 40' Party Time), boat and watersports rentals (pontoon, Carolina skiff, kayak, jet ski, pedalboard), and ancillary services (dockage, bait shop, boat club membership, boat services, film location services, and branded merchandise). All passenger vessels are USCG-certified, and the Tursi-ops vessel carries a hydrophone that allows passengers to hear dolphin vocalizations underwater — a notable technical differentiator.

The company serves a diversified customer base including vacationing families and tourists in the Myrtle Beach area, local residents, educational groups (homeschool families, school field trips), and groups pursuing celebrations (birthday parties, bachelor/bachelorette parties, corporate events). Revenue is generated primarily through transaction fees on activity tickets and rentals, with unit pricing ranging from $25 (kayak rentals) to $299 (pontoon rentals) and fishing charters up to $169 per person for Gulf Stream trips. Dockage services provide a more recurring revenue stream with nightly rates starting at $143 plus per-foot overages. The company distributes through the FareHarbor third-party booking platform, phone reservations, and walk-ins, and amplifies demand through organic social (Facebook, Instagram, X), TripAdvisor, blog content, and cross-promotion with MarshWalk restaurants. The business is privately held with no institutional investment, no parent company, and no disclosed management team beyond a general reservations contact.
