Vessel Safety Check

Vessel Safety Checks can be performed by any USCG-approved marine deputy. They can be performed at any time while on the water. (While these checks are at your request, they are subject to the availability of the Marine Unit at that time.) Safety checks may also be done by appointment, either at the Bay County Boat Ramp of your choice, or at your home marina. These appointments may be made by contacting the Bay County Sheriff's Office at (989) 895-4050. See the attached form for sample vessel safety check information.
