Founded in 2017 by Captain Don Grigg, CDM Yachts runs yacht charters in Point Loma on Shelter Island Drive. The fleet spans a Sunseeker Manhattan 75, Sunseeker Predator 68, Hatteras 68, Sea Ray 560, Carver Voyager 53, Cruisers Yachts 447, Tiara 44, and Luhrs 320 Express — one of the broader private-fleet rosters on Shelter Island alongside brokerage-and-charter neighbors including Alana Yacht Rental. Each yacht runs USCG-compliant with a maximum of 13 passengers per uninspected-vessel law, pairing a licensed captain with the guest group on a two-hour rental minimum that most bookings extend into half-day or full-day charters. Services extend beyond charters into yacht management, vessel delivery and relocation, private instruction, and captain-for-hire assignments, with Catalina Island day-and-night cruises overlapping destinations hit by Point Loma sail-and-motor peers including Cerulean Sea Charters. Overnight and multi-day custom charters aboard the 75-foot Sunseeker Manhattan represent the most involved bookings the company handles, requiring multi-day captain rotations, provisioning, and Catalina or Mexican-water routing.
