WaveRunners, kayaks, stand-up paddleboards, and powerboats launch directly from the Full-Service Marina at 1404 Vacation Rd in the 92109 zip code, operated by Action Sport Rentals on the grounds of Paradise Point Resort. The marina sits on a 44-acre island resort in Mission Bay, giving renters immediate access to calm, protected waters ideal for beginners and families. Action Sport Rentals stocks the dock with a rotating fleet that includes Duffy electric boats for leisurely cruising, pontoon party decks, sailboats, and high-speed WaveRunners for riders looking for more adrenaline. Land-based rentals are also available, with surreys, cruiser bikes, and tandem bicycles for exploring the resort's bayfront paths. Guests staying at the nearby San Diego Mission Bay Resort often walk over to rent equipment for an afternoon on the water without needing to drive. The marina operates daily from 9 a.m. to 5 p.m., with all rentals due back by 6 p.m., though summer weekend hours extend to 6 p.m. with a 7 p.m. return window. Brief introductory lessons for paddleboarding and kayaking are offered to help first-timers get comfortable before heading out. Action Sport Rentals runs seven total locations across San Diego, including outposts at the Hilton San Diego Resort on Mission Bay and several San Diego Bay sites. Reviewers frequently mention the ease of the check-in process and the staff's patience with families and young children. Afterward, the marina's Mission Bay setting is a short drive from Single Fin Surf Grill for tacos and cold drinks with a surf-culture vibe. Online booking is available through the Action Sport Rentals website, and credit cards are accepted on site.
