Sideslipping ............................. Sideways, rather than forward, motion of the hull, prevented by the use of a centerboard, daggerboard, leeboard, or keel.
Spreader ...................................A short horizontal spar near the midpoint of the mast that spreads the shroud away from the mast to increase leverage and stability.
Square knot .............................A pair of overhand knots that is useful for tying two lines together quickly and securely. Stand-on vessel ...................... Under the Navigation Rules, the vessel that maintains course and speed. Standing rigging .....................A set of wires called shrouds and stays used to help the mast stand upright. Starboard ................................. The right side of a boat when looking forward. Starboard tack ........................A boat’s attitude when it is sailing with the wind coming from the starboard side. Starboard-tack boat .............. Under Navigation Rules, the boat that maintains course and speed when meeting a boat on port tack.
Stays ........................................... Pieces of standing rigging that hold the mast from moving forward and back. Stern .......................................... The back end of any hull.
3 Ts ............................................. Tiller toward trouble, the safety maneuver to steer away from hazards. Tack ............................................ The corner of a sail between the luff and the foot. Tacking ...................................... To change directions by turning the boat’s bow through the wind. Like “hard to lee,” tacking can be the helmsman’s warning when putting the helm down to tack through the wind.
Telltales ..................................... Pieces of yarn or cloth attached to the shrouds or stays to help show the flow of air and wind’s direction.
Tender ........................................A small boat, usually propelled by oars or an engine. Tide ............................................ In bodies of water open to the ocean, the rise and fall of the water level on a predictable schedule due to gravitational pull.
Tiller ........................................... The lever attached to the rudder to steer a boat. Tiller extension ........................A short lever hinged to the forward end of the tiller to enable the helmsman to steer while sitting farther forward and away from the tiller itself.
Trim ............................................. The adjustment of sails in or out to find the optimum setting in relation to the wind direction and strength.
“Trim in” .....................................A command for pulling in a sheet to adjust a sail. Trimaran .................................... A form of multihull boat with three hulls. Trimtales .................................... Yarn or cloth attached to both sides of a sail near the luff to show the flow of air across the sail and allow the adjustment of the sail until they stream straight back to indicate the optimum trim.
Upwind ...................................... The direction of movement toward the wind. Upwind sailing ......................... Sailing in the direction of the wind, which includes close reaching and close-hauled sailing.
Vang ........................................... See Boom vang.
Weather eye............................. Attention to warning signs of changes in wind, tide or weather. Windward ................................. The direction, in relation to the boat, from which the wind is blowing. Windward boat .......................
