Family-owned since 1976, Seaforth Boat Rentals is a boat rental and water sports service at 1641 Quivira Rd in the 92109 zip code. Operating as the longest-running boat rental company in San Diego, Seaforth maintains a fleet of more than 200 vessels across five locations covering Mission Bay and San Diego Bay. The Mission Bay location on Quivira Road puts renters minutes from open water, with powerboats from 16-foot runabouts to 56-foot yachts, sailboats from 22 to 54 feet, jet skis, kayaks, and stand-up paddleboards. The same stretch of Quivira Road is home to Sportsmen's Seafoods, where boaters often stop for freshly caught fish right at the dock after returning from a morning cruise. No boating license is required for rentals, and all experience levels are welcome. Captained charters let groups sit back while a licensed skipper navigates, with options like the Party Cat 46-foot pontoon cruiser and the custom-built Limo Boat designed for on-water entertaining. Seaforth also runs a sailing club with membership tiers and offers certified sailing courses for anyone looking to build skills on the water. Seasonal promotions appear regularly on the company's website, including discounted spring and summer rates for boats 25 feet and under. The operation extends to Seaforth Yacht Charters, a dedicated division for multi-night trips to Catalina Island aboard motor yachts, and the Quivira Basin location sits steps from Dockside 1953 for waterfront cocktails after a day on the bay. Couples can also book the private Romantic Sunset Sail or a champagne brunch cruise aboard one of the fleet's luxury vessels.
