Age and Horsepower Restrictions:
Mandatory Boater Education
To operator a motor driven boat of 15 horsepower or greater, a person must be at least twelve years of age or older and complete a boating safety course that is accepted by both Washington State Parks and Recreation Commission.

By January 1, 2016, all boat operators meeting the requirements must have an education card.
Exemption: persons who have a U.S Coast Guard vessel operator's license, or persons visiting Washington State.
Mandatory boater safety education will be phased in as follows:
January 1, 2008 – All boat operators twenty years old and younger;
January 1, 2009 – All boat operators twenty-five years old and younger;
January 1, 2010 – All boat operators thirty years old and younger;

January 1, 2015 – All boat operators who are required to have a card will be phased in.
All boat operators born before 1/1/1955 will not be required to have a boat operator education card.
Age/Horsepower Restrictions
No person under 12 years of age can operate a motorboat of 15 or more horsepower.
Persons who do not have a boater education card and are 12 years of age or up can operate a vessel with more that 15 HP if accompanied by and under the direct supervision of a person 16 years of age who has a boater education card.
Boat Rental Requirements
Beginning January 1, 2008, those operators who are required to have a boating education card and wanting to rent a vessel, must present the card to livery (rental) operators. If the person, required to have a boating education card, does not have a boating education card, the livery operator must complete an operation and safety checklist with the vessel renter prior to the renter being allowed to use the vessel on the water.
