BEAR OFF/BEAR AWAYTo turn the board away from the direction the wind is coming from. Same as head down, fall off, bear off.
BEACH STARTA method of mounting the board in knee-deep water with the sail flying.
BEATTo zigzag your path of travel against the wind to reach a point upwind of you.
BOOMThe “handle” of your sail. It’s where you’ll hold on most of the time.
CENTERBOARDLarge retractable fin found on longboards and learning boards. Helps provide stability and enhances a board’s upwind capabilities.
CLEWBack corner of the sail.
DOWNHAULThe rope attached to the mast base that pulls the sail down onto the mast.
DOWNWINDDirection the wind is blowing to, or a path of travel.
FINAttached to the bottom of the board at its tail, it provides directional stability.
FOOT STRAPSFoot straps allow more board control and foot steering at high speeds for advanced sailors.
GRID CONSTRUCTIONA modern sail material such as X-Ply or Pentex that is reinforced for toughness.
HARNESS LINESLines attached to the boom used for hooking in to a harness.
HEAD UPTo turn the board toward the direction the wind is blowing from.
JIBETo change the board’s direction 180 degrees by turning downwind.
LITERSThe unit of measurement of a board’s volume – the number of liters of water it would displace if submerged.
MAST BASEAttaches the U-joint to the board.
MONOFILMClear, lightweight plastic material used in modern sails.
NOSEThe front of the board, often slightly pointier than the board’s tail.
OUTHAULThe line that connects the back corner of the sail (the clew) to the boom.
PLANEIn windsurfing, it’s when the board gains enough forward speed to break free of the water and skim the surface, reducing drag and allowing the fastest speeds.
Other good stuff to know
PORTTo the left of the forward motion. Sailing on port tack is sailing left hand forward. Port tack yields right of way to starboard tack.
RIG (noun)
The combination of sail, mast, mast base and boom after it is assembled; (verb) to assemble these components.
STARBOARDTo the right of the forward motion. Sailing on starboard tack is sailing right hand forward. Starboard tack has right of way over port tack.
TAILThe back end of the board, usually the squarer end. This is the end with the fin.
TACK ( verb)
To turn the board upwind, through the direction the wind is coming from, so you can start sailing in a new direction. Opposite of the jibe, and useful for gaining upwind ground.
UNIVERSAL JOINT (U- joint)
Component that connects the sail to the board that allows it to move in any direction.
UPHAULA rope attached to the rig that is used to pull the sail up and out of the water.
UPWINDToward the direction the wind is coming from.
VOLUMEA measurement of a board’s displacement, which correlates directly with its flotation. The more volume, the more float.
WATER STARTA technique used by intermediate or advanced sailors in which the sail lifts them from the water onto the board. A necessary skill for sailing smaller boards that don’t provide enough float to stand on and uphaul the sail.
