The hull is the part of the boat without masts, spars, oars, or
rigging.

The keel, like the runner of a skate, runs along the center of the
bottom of the boat. It keeps a boat under sail from sliding sideways.

Starboard is the right-hand side of the boat as you face the bow.

Port is the left-hand side, looking in the same direction.

After dark ships and boats carry a red light at the bow on the port
side, and a green light on the starboard.

The Rudder is a movable piece of board at the stern, by means of which
the craft is steered. It is worked by a lever, ropes, or a wheel. The
lever is called "the tiller."

The Helm is that part of the machinery you grasp when steering.

The Deck is the roof of the hull.

The Center Board is an adjustable keel that can be lowered or raised
at pleasure.

The Masts are upright poles to support the rigging and sails.

The Yards are poles hung on the masts at right angles to them, from
which the sails hang when in use, and on which they are furled or
folded when not in use.
