Reefing is the means of reducing the area of a sail, usually by folding or rolling one edge of the canvas in on itself. The converse operation, removing the reef, is called “shaking it out.” Reefing allows the carrying of partial sail in strong winds, and is the primary safety precaution in rough weather.
When should I Reef my sails?
When to reef? Most boats are designed to require the first reef in around 18 knots apparent wind when sailing to windward. Some lighter, more coastal-orientated boats may struggle in 15 knots while heavier offshore designs will still be happy at 20 knots or more.
How do you reef a jib sail?
To reef the sail, first ease the sheet to reduce the load on it, and then pull in the furling line. Make sure you keep some tension on the sheet while the sail is being furled. You should be able to reef a furling genoa on a 40-footer by hand – be very careful if you are using a winch.
What is furling a sail?
Furling refers to stowing or dousing a boat’s sail by flaking (folding), packing (like stuffing a spinnaker into a bag), or stowing it in part or whole using roller furling.
How do you reef when sailing downwind?
The process is very straightforward and the steps are as follows:
- Place the boat on a stable downwind heading typically with the wind fine on the windward quarter.
- Release the boom vang.
- Tension the topping lift, ensuring the boom is elevated a little at the outboard end.
What does it mean to put a reef in the main?
Typically it involves lowering the sail a few feet and tying up the extra material in some fashion onto the boom, thereby establishing a new tack and clew. Figure it out and put in a reef, then shake it out.
How do you reef a furling mainsail?
How to use a furling mainsail
- Sail upwind.
- Release the main sheet.
- Open both continuous line’s jammers.
- Pull the outhaul until you get the size of sail you want.
- Pull both sides of continuous lines and put jammers on to secure your reefing.

Can you reef a jib?
If they are furled around the forestay then it is very simple to reef them. You simply roll them up a little in order to decrease their size. Typically there will be two stripes marked on the foot of the jib/genoa. … You pull the inhaul to wind it up while managing the slow release of the jib sheets.
Are catamarans safer than sailboats?
Mike Kiely: Catamarans are very stable and have natural buoyancy, making them unsinkable. Yes, they can capsize in a bad accident, but it’s better to be rescued floating on the water’s surface than sinking to the bottom in a monohull. Plus, moving around on a flat deck is much safer than on a deck at an angle.
What is the difference between a jib and a genoa sail?
Colloquially the term is sometimes used interchangeably with jib. A working jib is no larger than the 100% foretriangle. A genoa is larger, with the leech going past the mast and overlapping the mainsail. … Working jibs are also defined by the same measure, typically 100% or less of the foretriangle.
How does a sail furler work?
In this roller furling system, the jib is hoisted in a groove, but when not in use is furled around the headstay, rather than lowered. To furl the sail you simply pull on a line that leads from a drum at the base of the jib aft to a winch near the cockpit, which rotates the whole headstay, rolling up the jib.
How do you sail down wind?
A general rule of thumb in sailing downwind is that the more you head off away from the wind, the more you let your sails out. On a run, your sails should be eased as far as possible so their maximum area is exposed to the wind.
What is a topping lift on a sailboat?
The topping lift (more rarely known as an uphaul) is a line which applies upward force on a boom on a sailboat. Part of the running rigging, topping lifts are primarily used to hold a boom up when the sail is lowered. This line would run from near the free end of the boom(s) forward to the top of the mast.
