BOATS
Glossary of Terms
Propeller Shaft: Shaft which runs from the back of
the engine gear box, aft, through the stufng box,
shaft log, struts, and onto which the propeller is
attached.
Pyrotechnic Distress Signals: Distress signals that
resemble the brilliant display of ares or re-
works.
Raw Water Cooled: Refers to an engine cooling
system that draws seawater in through a hull t-
ting or engine drive unit, circulates the water in
the engine, and then discharges it overboard.
Reduction Gear: Often combined with the reverse
gear so that the propeller turns at a slower rate
than the engine.
Reverse Gear: Changes the direction of rotation
of the propeller to provide thrust in the opposite
direction for stopping the boat or giving it stern-
way.
Roll: A boat’s sideways rotational motion in rough
water.
Rope Locker: A locker, usually located in the bow
of a boat, used for stowing the anchor line or
chain.
Rubrail: Railing (often rubber or hard plastic)
that runs along the boat’s sheer to protect the
hull when coming alongside docks, piers, or other
boats.
Rudder: A moveable at surface that is attached
vertically at or near the stern for steering.
Sea anchor: An anchor that does not touch the
bottom. Provides drag to hold the bow in the most
favorable position in heavy seas.
Scupper: An opening in the hull side or transom
of the boat through which water on deck or in the
cockpit is drained overboard.
Sea cock: Safety valves installed just inside the
thru-hull ttings and ahead of the piping or hose
running from the ttings.
Shaft Log: Pipe through which the propeller shaft
passes.
Sheer: The uppermost edge of the hull.
Sling: A strap which will hold the boat securely
while being lifted, lowered, or carried.
Slip: A boat’s berth between two pilings or
piers.
Sole: The deck of a cockpit or interior cabin.
Spring Line: A line that leads from the bow aft or
from the stern forward to prevent the boat from
moving ahead or astern.
Starboard: The right side of a boat when facing
the bow.
Steerageway: Sufcient speed to keep the boat
responding to the rudder or drive unit.
Stem: The vertical portion of the hull at the
bow.
Stern: The rear end of a boat.
Stow: To pack away neatly.
Stringer: Longitudinal members fastened inside
the hull for additional structural strength.
Strut: Mounted to the hull which supports the
propeller shaft in place.
Strut Bearing: See “cutlass bearing.”
Stufng Box: Prevents water from entering at the
point where the propeller shaft passes through
the shaft log.
Superstructure: Something built above the main
deck level.
Swamps: When a boat lls with water from over
the side.
Swimming Ladder: Much the same as the board-
ing ladder except that it extends down into the
water.
Taffrail: Rail around the rear of the cockpit.
Thru-hull: A tting used to pass uids (usually
water) through the hull surface, either above or
below the waterline.
Topsides: The side skin of a boat between the wa-
terline or chine and deck.
