In California you must be 16 or older and hold a California Boater Card to operate a vessel powered by a motor of 15 horsepower or more, including a personal watercraft. Someone aged 12 to 15 may operate that same class only while supervised on board by a person at least 18 who is also in possession of a California Boater Card. The supervising adult needs the card, not just the years. State Parks' Division of Boating and Waterways administers it. The rental company sets its own minimum rental age, often higher, so confirm it when booking.

California requires a Boater Card, rather than a conventional boating license, for most recreational operators of motorized vessels. Since January 1, 2025, the requirement applies regardless of age and includes personal watercraft. Operators generally must be at least 16 for vessels over 15 horsepower; ages 12 to 15 may operate only if supervised on board by an attentive adult 18 or older, and must either hold a card themselves or be supervised by a cardholder.

Rental vessel operators are exempt. Exemptions also cover direct supervision and qualifying temporary visitors. Approved applicants may print a 90-day temporary card while awaiting the permanent card. California State Parks’ Division of Boating and Waterways administers the program.

From Alameda, point a rental toward San Francisco Bay, Ballena Bay, Oakland Inner Harbor or San Leandro Bay. Use Encinal Boat Ramp for the bay side; it is a public two-lane launch with docks for motorized and nonmotorized craft. San Francisco Bay is the open-water option, while Ballena Bay is a protected small-craft harbor that NOAA describes as safe refuge in storms.

Grand Street Boat Ramp is the city put-in for the Oakland Inner Harbor side. The harbor is marina-lined and wake-sensitive; it connects San Francisco Bay to Tidal Canal and San Leandro Bay. San Leandro Bay is shallower near the narrow, uneven San Leandro Channel.

From Alameda, boaters can head to Ayala Cove on Angel Island, Clipper Cove at Treasure Island, or Jack London Square in Oakland. Ayala Cove offers public day use slips and access to picnic areas, trails and historic sites. Clipper Cove is a designated short term anchorage for recreational vessels. Jack London Square combines guest berths and marinas with waterfront dining, shops, plazas and walkways along the Oakland waterfront.
