Boating and Houseboat Laws in California

If you own a houseboat and live in California or are looking to use your boat in California, then understanding what the boating laws are is vitally important. In this article we will give you an overview of the boating laws in California as well as try to explain them in normal terms rather than the legal mumbo jumbo. 

California Boater Education Laws

  • California is one of the strictest states in regards to boater education. By January 1, 2025 they will require every driver of a boat to possess a boater education card. They are phasing that in over several years by increasing the age limit by 5 years every year since 2018. Source The boater card cost $10 for a lifetime card and the boater course costs from $20-$40.

California Boat Mooring Laws

  • Attaching your boat to any buoy (besides a mooring buoy) is prohibited. 

California Boat Traffic Laws

  • Boats meeting one another within half a mile must signal their direction intention by 

One short blast = I intend to leave you on my port side. 

Two short blasts = I intend to leave you on my starboard side. 

Three short blasts = I am operating astern propulsion. Source

  • If in fog, boats should sound long blasts not more than 2 minutes apart while moving. If not moving you should sound two long blasts in succession with about 2 seconds between the blasts.

California Boat Anchoring Laws

  • Anchoring is allowed but laws vary city by city. Most cities allow anchoring for up to 96 hours before they require a 24 hour “break”. Other cities charge a daily rate to allow you to anchor there. Check with the city/town where you intend on anchoring and find the applicable laws in that area. I wrote a complete article on places where you can anchor on the California Coast. That article can be found here

That covers the basics of California houseboat laws. There are many additional laws that are have obscure exceptions or that don’t apply to houseboats that we didn’t cover above. Please check out the ABCs of California boating for additional information on specific California boating laws.

I love the outdoors and especially spending time with my family. Whether on a boat or at the beach, my happy place is near the water.
