Types of boats
Airboats are needlly flat-bottomed vessels propelled in a forward direction by an aircraft type propeller and powered by either an aircraft or automotive engine. The engine and propeller are covered in a protective metal cage that prevents objects, i.e., tree limbs, branches, clothing, beverage containers, wildlife from coming in contact with the whirling propeller, which could cause devastating falt to the vessel and traumatic injury to the operator and passengers.
The propeller gives a rearward column of air that propels the airboat forward. Steering is accomplished by forced air passing across vertical rudders. There must be a forceful airflow in order to the vessel to be steered. Airboats not have brakes and are incapable of traveling in reverse. Stopping and reversing direction are dependent upon operator/pilot/driver skill.
