Slab reefing
Slab reefs are a simple, quick way of taking a 'slab' out of a sail.
REEFING: Reducing the amount of sail area in strong winds
REEVE: To pass the end of a rope or line through a hole or aperture such as an eye, block or fairlead.
RIG: The arrangement of a boat's mast, sails and spars.
Reefing: Reducing the amount of sail area.
Rig: The arrangement of a boat's mast, sails and spars.
Rudder: Underwater part of a boat used for steering.
reefing lines - Lines used to pull the reef in the sail. The reef line will pass through reef cringles, which will become the new tack and clew of the reefed sail.
reeve - Leeding a line through a block or other object.
Reefing To reduce the area of sail, especially the mainsail, when the wind freshens and the boat is overcanassed.
Reefing To reduce sail area by taking in at the reef points.
Round turn To put a turn around a bollard to hold the strain on a rope under tension.
Rules of the Road USCG navigational rules for all vessels.
slab reefing
Also points reefing, and sometimes jiffy reefing. Reducing the area of the mainsail by partially lowering the sail and re-securing the new foot by tying it to the boom with points or lines attached to the sail.

jiffy reefing
A method of lowering the sail in sections so that it can be reefed quickly.
jig ...
jiffy reefing - A fast method of reefing, where the reef that is tied in. Lines pull down the luff and the leech of the sail, reducing its area.
jigger mast - The mizzen mast of a yawl or dandy.
Jiffy reefing A fast method of reefing. Lines pull down the luff and the leech of the sail, reducing its area.
Jumper stay A short stay supporting the top forward portion of the mast.

On a cutter this is the forward most sail, as opposed to staysail located between the jib and the main. jibe: also gybe; changing from one tack to the other when sailing downwind. jiffy reefing: a fast method of reefing.
Scandalize - To reduce the area and efficiency of a sail by expedient means (slacking the peak and tricing up the tack) without properly reefing, thus slowing boat speed. Also used in the past as a sign of mourning.
Scow - 1.
Reefing-The operation of reducing a sail by taking in one or more of the reefs.
Reef-bands- Pieces of canvass, about six inches wide, sewed on the fore part of sails, where the points are fixed for reefing the sail.
The mechanical reefing of topsails and top-gallant sails was introduced about 1858, but only remained in favor for a few years; double topsails, on the other hand, first used in the four-masted American shipentine clipper Great Republic, ...
"All yachtsmen know what a disagreeable job it is to reef a sloop or catboat in rough water, and from this cause many skippers will delay reefing as long as possible and often until too late. And because of this many accidents happen yearly.
REEFING - To reduce the area of a sail by rolling and tying up a portion of it. Also to shorten the bowsprit by hauling it partly in board.
Heaving to can be useful for reefing (or dropping) the main. In fact, if conditions are rough or you don't have an autopilot, heaving to whilst reefing comes in pretty handy.
Furling booms are becoming more popular and they make sense, it is better to lower sail than to move it forward when reefing. However, in-mast systems are well proven and very simple to operate.
In roller reefing, the sail is either rolled around a wire at its luff or lowered, a few feet and rolled around the boom.
Finally, rig the reef outhaul between the aft reef grommet and the end of the boom, using a Reefing Clew Line, with a cross-turn under the bottom of the boom.
Reduce sails or running with bare poles : Reduce the ship's sails by reefing the main or going to a storm trysail ( a small heavy weather sail ) and by hoisting a storm jib ( even smaller than a number 4 jib ).
Furling the jib is often the first step to sailreefing on sailboats with furling systems. The sail area must still be reduced. Newer sailors might furl in the jib, start the engine and then reef. But that will leave you in the mercy of the waves.
The following pages explain the furling and jib reefing process.

Reef point- Small rope used in reefing. These ropes are attached at intervals across the sail.
Rigging- All lines, shrouds and stays on a boat that pertain to the sail and masts.
Rode- Line that attaches to an anchor.
Light line on a sail to assist in reefing. Several rows, allow single, double, or treble reefing.
Reef tackle
Blocks and ropes used to reef sails.
You will notice reefing points on the Munin sail but we don't sail in high winds. There are two ways for the helmsman and crew to alter course and turn the boat through the wind.
Footropes - ropes on square-rigged ships which hang below the yards, on which sailors stand while reefing or furling sails.
Fore - the front part of the ship. "She had sustained damage in the fore." ...
Reef knot. A simple knot that can slip. Often used on sailboats when reefing.
Square Rigged
A sailboat having square sails hung across the mast.
Never go to sea unless you are able to easily reduce sail area. Does your reefing work properly, and does the storm jib really fit?
Furl
To lower a sail. Sails are sometimes partially furled to reduce the amount of sail area in use without completely lowering the sail. This is usually known as reefing.
