SD Marine Group

What SD Marine Group does

SD Marine Group (SD Marine LLC) is a privately-held, multi-brand marine dealership headquartered in Islamorada, Florida, with a secondary location in Key Largo. The company sells new and pre-owned vessels from premium OEMs including Sea Fox, Caymas, Coastal Skiff, Tiara Yachts, HCB, SeaHunter, and Costa Carts electric vehicles/golf carts, and operates as a Florida State Licensed Yacht Brokerage. Its target customers are recreational boaters, sport fishing enthusiasts, and affluent South Florida buyers seeking offshore, bay, and flats fishing vessels, with secondary segments in family boating and luxury/performance buyers.

The company's revenue model is a mix of one-time retail sales on new and pre-owned boats, brokerage commissions on transactions, affiliate referral income from a Sheffield Financial partnership, recurring subscription revenue from boat storage, and professional services revenue from maintenance, repair, and electronics work. Pricing is quote-based ("Call for Pricing") with no public list pricing, and financing is offered through Sheffield Financial with terms of 7-9% APR over 20-year amortization. The go-to-market is direct-to-consumer through two physical dealership locations supported by a website with inventory browsing, online request-for-information, and financing pre-qualification, layered with content marketing (blog, buyer guides), social media (Facebook, Instagram, YouTube), email newsletters, and community events.

The business is a small, person-operated enterprise with 10 employees and two physical locations along the Overseas Highway. There is no in-house technology platform, no proprietary software, and no AI/ML capabilities; the technology stack consists of standard marine OEM electronics (Garmin, JL Audio, Mercury) installed on inventoried vessels. The company is funded as an independent, privately-held business with no disclosed institutional investors, no parent company, and no M&A or funding activity in the available data.
