COUNTER

The part of the stern above the waterline that extends beyond the rudder stock culminating in a small transom. A long counter increases the waterline length when the boat is heeled, so increasing hull speed.

LEE HELM

The tendency of a sailboat to turn to leeward in a strong wind when there is no change in the rudder's position. This is the opposite of weather helm and is the result of a dynamically unbalanced condition.

FIXED PROPELLER

A propeller mounted on a rigid shaft protruding from the hull of a vessel, usually driven by an inboard motor; steering must be done using a rudder. See also outboard motor and sterndrive.

A motor mounted externally on the transom of a small boat. The boat may be steered by twisting the whole motor, instead of or in addition to using a rudder.

STEERING BOARD

A long, flat board or oar that went from the stern to well underwater, used to steer vessels before the invention of the rudder. Traditionally on the starboard side of a ship (the 'steering board' side).
