California boat rental laws
3 rules for boat and jet ski rental businesses in California, from 2 official sources.
Rental-specific lawSince 1 January 2025 every operator of an engine-powered vessel in California needs a California Boater Card — but a person operating a rental vessel is exempt. The age limits for boats over 15 hp (including PWCs) still apply to renters.
Boater education card for renters
-
No one may operate a vessel propelled by an engine (even an auxiliary one) without a California vessel operator card; since 1 January 2025 this applies to all persons regardless of age.
Show the official wording
Cal. Harb. & Nav. Code § 678.11“a person shall not operate on waters subject to the jurisdiction of the state a vessel that is propelled by an engine, regardless of whether the engine is the principal source of propulsion, unless the person has in his or her possession a vessel operator card”
-
The card requirement does not apply to a person operating a rental vessel.
Show the official wording
Cal. Harb. & Nav. Code § 678.11“This section does not apply to any of the following: … (4) A person operating a rental vessel.”
Age limits
-
No one under 16 may operate a vessel with a motor over 15 hp (PWCs included); 12- to 15-year-olds may only with an attentive, supervising person of 18 or older aboard.
Show the official wording
Cal. Harb. & Nav. Code § 658.5“no person under 16 years of age shall operate a vessel powered by a motor of greater than 15 horsepower”
Not confirmed yet
What we looked for and could not confirm from an official source. Ask the agency before you assume anything here.
No California statute requiring rental businesses to give renters instruction, keep records or hold a state rental licence was found in the sections read (Harbors and Navigation Code §§ 658.5, 678.11).
Whether California's PWC rules include duties specific to PWC rental operators was not confirmed.
Local rules (harbor districts, lakes, county ordinances) that often govern rental concessions were not reviewed.
Federal rules still apply
On top of California law, the federal rules apply to every boat you rent out:
-
Under federal law a boat leased, rented or chartered to someone else for their pleasure is a “recreational vessel” — so the federal recreational boating rules apply to your rentals.
Show the official wording
46 U.S.C. § 2101 — General definitions“"recreational vessel" means a vessel— (A) being manufactured or operated primarily for pleasure; or (B) leased, rented, or chartered to another for the latter's pleasure.”
-
Every recreational vessel needs at least one wearable Coast Guard-approved life jacket on board for each person, used as its approval label says; boats 16 ft or longer also need one throwable device.
Show the official wording
33 CFR § 175.15 — Personal flotation devices required“At least one wearable PFD is on board for each person; … No person may use a recreational vessel 16 feet or more in length unless one throwable PFD is onboard”
-
A child under 13 aboard a recreational vessel under way must wear a Coast Guard-approved life jacket unless below decks or in an enclosed cabin. Where a state has its own child life jacket law, the state age applies on its waters instead.
Show the official wording
33 CFR § 175.15(c) and § 175.25“No person may operate a recreational vessel under way with any child under 13 years old aboard unless each such child is either— ( 1 ) Wearing an appropriate PFD approved by the Coast Guard; or ( 2 ) Below decks or in an enclosed cabin.”
-
If the state has a statute requiring children of a certain age to wear a life jacket, that state requirement applies on the state's waters instead of the federal under-13 rule.
Show the official wording
33 CFR § 175.25 — Enforcement of State requirements for children to wear personal flotation devices“If the applicable State statute establishes any requirement for children of a certain age to wear an appropriate PFD approved by the Coast Guard, then that requirement applies on the waters subject to the State's jurisdiction instead of the requirement provided in § 175.15(c) of this part .”
