Operating out of the Kona Kai Resort dock on Shelter Island in Point Loma, Action Sport Rentals runs a multi-vessel fleet of WaveRunners, 21-foot Duffy electric cruisers, solar Funcat catamarans, kayaks, and stand-up paddleboards. The Funcat and Duffy lineups suit slower bay cruising while the sit-down personal watercraft fleet runs faster across San Diego Bay for renters 21 and over, with a Shelter Island pier stop at Fathom Bistro, Bait, and Tackle available on the same peninsula for pre- or post-rental meals. Renters need a valid driver's license and must be at least 18 for powerboats, with no prior boating experience required since operational briefings happen at the dock. Beyond the motorized fleet, the outfit stocks surreys, beach cruisers, and paddleboards for low-speed bay tours, a category overlap with paddle-sport retailers like WEST COAST PADDLE SPORTS - Retail Shop where rental customers transition into owning gear. Online reservations lock in up to one hour before start time, with the broader Action Sport footprint covering seven San Diego locations including Mission Bay, Dana Landing, and the Bahia Resort. The most complex coordination the Shelter Island desk handles is a multi-vessel private-event rental that combines powerboats, Funcats, and waverunners for groups staging off Kona Kai's private beach.
