Sail located along aft edge of tallest mast
Main or mainsail
Sail that sets in front of mast
Headsail - most common is jib (large jibs that overlap mast are genoas)
Weight of boat in water is called…
Displacement (pushes aside a volume of water equal to its rate)
Top corner of a sail
Head
Fore, bottom corner of a sail
Tack
Aft, bottom corner of a sail

Cunningham
The control line system mounted on the boom used for controlling the tension of the foot of the mainsail (Controls depth in the bottom of the mainsail)
Outhaul
A sail control system that can move the lower mainsheet attachment point on the boat from side to side (changes angle of attack without changing the sail’s twist)
Traveler

Boom Vang
The outer side of the stern
Transom
The distance between the deck of the boat in the water; The height of the top sides
Freeboard
The distance from the water’s surface to the deepest point on the boat
Draft/draught
The amount and position of fullness in a sail
Draft/draught
The outer sides of the hull
Topsides
The width of the boat at any point
Beam
The water level on the hull
Waterline
Draw - “our boat draws 6 feet”
Same as draft (or draught)
All wires that support the mast, including forestay, shrouds, & backstay
Standing rigging
Halyardlike control line running from the mast; used to lift the outboard tip of the spinnaker
Topping lift
Additional dock lines that are tied from the middle of the boat at opposite angles to the dock lines to prevent the boat from surging forward or backward
Spring lines
The support wires that run from the mast down to the edge of the deck on the port and starboard sides of the mast
Shrouds
The primary line that adjusts the sail’s trim
Sheet - main or jib
The moving “wheel” part of a block or pulley
Sheave
A metal fitting often used to attach a sail to a rope/line
Shackle
A boat’s navigation lights
Running lights
A mechanical fitting with a lever arm that cleats a rope
Jammer
A system of reducing the exposed sail area of a given sail
Reefing
Horizontal line of reinforced holes built into the sail to facilitate reefing
Reef points
Sailing with the wind coming over the port side of the boat
Port tack
Flapping motion of sailcloth when a sail is undertrimmed or not trimmed at all
Luff
Poles around deck that hold lifelines
Stanchions
When a boat has stopped moving & is stuck pointing directly into the wind
In irons
When boat leans to one side
Heel
Snaps or clips at intervals along the luff of a jib, used to attach it to the forestay
Hanks
The spinnaker sheet (control rope) on the windward side that attaches the through a fitting on the spinnaker pole to the tack
Guy/afterguy
Fitting that attaches the boom to the mast
Gooseneck
To roll or fold a sail & secure it
Furl
To sail slightly lower than close-hauled in order to go faster
Foot
A metal pin that secures a shackle or other fitting Ina boat
Clevis pin
The closest course to the wind that you can effectively sail
Close-hauled : also - upwind, on the wind, beating
A reach at any heading between 90° to the wind & close-hauled
Close reach
Attachment point of standing rigging on the hull
Chain plate
Reaching at a wide or broad angle to the wind (greater than 90°)
Broad reach
A sudden, unplanned turning of a boat toward the wind that occurs in strong winds
Broach
Horizontal pole that supports the bottom edge of the mainsail
Boom
A pulley through which lines run
Block
Reaching on a heading perpendicular to the wind direction
Beam reach
At right angles to the boat
Abeam
Partners
The point where the mast leaves the deck
Quadrant
Bracket around the rudder post that connects to the steering cables
Sheave
The moving wheel-shaped part that the rope turns over
Pawl
Gearing (?) that allows a winch to spin one way & not the other
In column
A straight mast
Bosun’s chair
A harness-type device that provides a seat & can be attached to the halyard
Attachment points for the standing rigging
Tangs
Ropes, webbing, or cables that run along the deck in either side of the cabin the length of the boat
Jack lines
Sailing to close to the wind
Pinching
Wind shift coming from farther ahead
A header
Wind shift coming from farther behind
A lift
Sailing the boat at a lower angle to the wind (to go faster)
Footing
Sailing the boat at a closer angle to the wind (slower but more direct to your destination)
Pinching
When close hauled or reached, boats tend to to turn toward the wind
Weather helm
Another term for Cunningham
Downhaul
To get every knot out of the mainsail…
Tighten halyard &/or cunningham and loosen them downwind
Increased luff tension usually moves draft position forward & decreases the depth of the sail slightly
Rule of thumb for boom vang
Put enough boom vang on (set when close hauled) so that the top batten is parallel to the boom
How to use a traveler for maximum upwind power
In light air: sailing windward, after mainsheet is trimmed for the right amount of twist, pull the traveler to windward, so BOOM IS ON CENTERLINE
In heavy air: reduce power by dropping traveler to leeward
The first fitting (usually a pulley or fairlead) through which each jib sheet (one on each side) passes as it comes from the sail on its way to the cockpit
Jib “leads” or “cars”
How to adjust sail twist in a jib
Moving jib leads/cars forward or aft
Halyard-like control line running from mast, used to lift he outboard tip of the spinnaker pole into position
Topping Lift or pole lift or topper
Line coming from the foredeck area, used to keep the outboard tip of the spinnaker pole from lifting too high
Foreguy or downhaul
Sailor’s slang for spinnaker
Chute
A rapid, out of control turn up toward the wind
Broach
