Courtesy Boat Inspectors

On weekends & holidays throughout the summer, trained Courtesy Boat Inspectors (CBIs) check boats, trailers, and related equipment for any invasive aquatic plants.

Although the Cobbossee Watershed contains just 10 of the 156 staffed public boat launches in the state, our inspectors are routinely responsible for over 10% of the state’s total yearly inspections.

Which boat launches do we cover?

We cover all ten public boat launches in the Cobbossee Watershed, which are depicted in the interactive map below. Our Courtesy Boat Inspectors are on duty at least 10 hours a day, every weekend and holiday from Memorial Day Weekend to Labor Day Weekend.


How do we perform our inspections?

Inspecting a boat doesn’t have to be hard, if you know where to look and what you are looking for!

In these short videos, John McPhedran of the Maine Department of Environmental Protection demonstrates how to do a thorough boat inspection in less than 4 minutes. The Maine DEP website also contains a useful Courtesy Boat Inspector Handbook.
