Courtesy Boat Inspections


What do courtesy boat inspectors, often call CBIs, do? As boaters launch and remove their boats from the water, CBIs:

  • Discuss with boaters how invasive aquatic plants spread
  • Show boaters how to inspect boats and equipment for plant fragments
  • Urge boaters to inspect before and after every launch
  • Distribute information about invasive plants
  • Articulate Maine law regarding the transport of these plants
