California law prohibits anyone from operating a vessel, water-skis, or similar device while under the influence of alcohol or drugs, or addicted to any drug. Alcohol and drugs cause impaired balance, blurred vision, poor coordination, impaired judgment (you’re more inclined to take risks when drinking), and slow reaction time.

Boating under the influence arrest
Boaters on California waters should be aware that:

  • It is illegal for anyone to operate a vessel, water-skis or similar device with a blood alcohol concentration of .08% or greater. A level of at least .05% but less than .08% may be used with other evidence in determining whether a person was operating under the influence.
  • Restrictions are more stringent for those under the age of 21. It is illegal for anyone under 21 to operate a vessel, water-skis or similar device with a blood alcohol concentration of .01% or greater.
