, Propeller - CORRECT ANSWER - rotates and powers a boat forward or backward

2 basic types of boat hulls? - CORRECT ANSWER - displacement and planing
Displacement Hulls - CORRECT ANSWER - Boats with displacement hulls move
through the water by pushing the water aside and are designed to cut through the water with very
little propulsion.
Planing Hulls - CORRECT ANSWER - Boats with planing hulls are designed to rise up
and glide on top of the water when enough power is supplied. These boats may operate like
displacement hulls when at rest or at slow speeds but climb towards the surface of the water as
they move faster.
Personal watercraft - CORRECT ANSWER - A small vessel that uses an inboard jet drive
as its primary source of propulsion, and is designed to be operated by a person or persons sitting,
standing, or kneeling on the vessel rather than inside the vessel.
Displacement Mode - CORRECT ANSWER - A planing hull, when operated at very slow
speeds, will cut through the water like a displacement hull.
Plowing Mode - CORRECT ANSWER - As speed increases, a planing hull will have a
raised bow, reducing the operator's vision and throwing a very large wake. Avoid maintaining a
speed that puts your boat in plowing mode.
Planing Mode - CORRECT ANSWER - Your boat is in planing mode when enough power
is applied so that the hull glides on top of the water. Different boats reach planing mode at
different speeds.
