cannot be removed until the board is brought ashore.
Centerboard : A pivoting foil-shaped blade that projects below
the bottom of a board to help prevent the board from sliding
sideways.
Daggerboard : A vertically moving foil-shaped blade that is
let down below the bottom of a board to help prevent the board from
sliding sideways. Similar to the centerboard, except it is raised and
lowered vertically rather than pivoted.

to the mast. This line also controls the tension on the luff.

Mast : The main vertical spar which supports the sail and boom.
Mast Foot : Where the mast and universal joint attaches to the board.
Outhaul : The line which is used to secure the clew of the sail
to the boom. This line is also used to control the shape of the
sail.
Port : The left side of the board.
Rig : The mast, mast foot, boom, sail and lines (outhaul,
downhaul, inhaul and uphaul ).
Skeg : The small vertical fin near the rear (stern) of the board.
Starboard : The right side of the board.
Tack : 1) The bottom corner of the sail
2) A turn through the wind. 3) A direction of sail.
Uphaul : 1) To hoist the rig by pulling on the sail's
uphaul. 2) A thick line which attaches to the boom to assist
in pulling up the rig and sail.
