There are many types of workboats on the rivers today. I have categorized them into four groups, utility boats, harbor boats, trip boats, and line haul boats . Utility boats range from 18' in length to over 50'. They perform specialized tasks such as crew boats, supply boats, tenders, bow boats, and truckables. Crew boats are used to transport personnel from boat to shore, boat to boat, or to barge fleets.
Supply boats deliver goods to the larger boats or to work barges.
Grocery delivery boats are in this class. A bow boat is used at the head of a tow for maneuvering. They can be piloted from a command station in the mother vessel's pilot house. Truckables are vessels that can be disassembled and placed onto trucks to be transported overland to remote locations. Harbor boats are vessels you'll find all up and down the river.
