The California Clean Boating Network consists of a collaboration of government, environmental, business, boating, and academic organizations working to increase and improve clean boating education efforts in California. Through the exchange of information and consideration of new trends in clean boating practices, CCBN members increase their ability to educate the boating public about clean boating practices.

The Need for
Boater Education

There are approximately one million boats registered in California. While most boaters appreciate the natural resources that abound in the watersheds in which they boat, many are unaware of the impacts boating can have on those resources. Water pollution problems associated with boating include discharges of oil, fuel, sewage, trash, fishing line, toxic cleaning and maintenance products, bottom paints, gray water, and invasive aquatic species. Members of the California Clean Boating Network (CCBN) believe that the contribution of pollution from boating to California’s waterways can be significantly reduced by educating boaters about the impacts of boating and about environmentally sound boating techniques.

Who Participates
in the CCBN?

CCBN members include environmental organizations, academic institutions, marine businesses, marine and boating associations, harbor patrol officers, port district commissioners, city and county officials, state agencies, the USCG & Auxiliarists, the US Power Squadron, National Estuary Projects, and others interested in boating education throughout the state.

Projects in the CCBN Action Plan

The CCBN "Action Plan" proposes a number of projects, some of which have already been completed. Projects include:
  • Catalog of Marina and Boater Pollution Education Materials. This catalog provides an easy way to obtain educational materials.
  • A list of oil and sewage disposal facilities, and other environmental services in California marinas. Available on the website.
  • Point of Purchase Displays. CCBN members have collaborated to education boaters through information posted at marine supply shops
  • Dockwalkers. CCBN member organizations exert “pier pressure” by training boaters to teach other boaters to be better environmental stewards.
  • Boat Show Outreach. CCBN members collaborate to provide education at boat shows throughout California.
