The jib's sheet controls the angle of the jib (sail) to the wind. It is attached to the lower end of the jib that is farthest aft.
The "jib" is the leading sail on a blow boat (sail boat). It determines your course, therefore is your guide. When someone likes the cut of your "jib" they are telling you that they see a person who is heading in the right direction and that they trust will do the right thing.
The number three jib is the smallest of three headsails on a sailboat and it is sometimes called a storm jib, because it is the one most likely used during storm conditions. If a boat has more than three headsails, the number three sail would be smaller than number two, but may not be the smallest headsail on the boat. For example if a boat has four jibs, say a 170, a 150, a 110 and a storm jib, then the 110 would be considered the number 3 jib and the storm jib would be number 4.
They are referred to as "sheets" as in "the main sheet" for controlling the mainsail & "the jib sheet" for controlling the jibsail.
In nautical terms, the "halyards" are used to "haul the yards" of sail (up or down). The mainsail halyard is called the "main sheet", the jib sail halyard is called the "jib sheet" & the mizzen sail halyard is called the "mizzen sheet".
This could be a sloop (main + jib), a cutter (main + jib + foresail), or a cat boat (main alone). There are many variations.
It is a type of sailing boat sail of triangular shape that is rigged in front of the mainsail.
A Jib is a secondary sail which is generaly smaller than the mainsail, and is usually possitioned at the frount of a boat (a foresail). It is generally triangular and is used to counteract the turning force of the mainsail around the pivot point of the vessel in some classes of boat.
the J dimension of a sailboat is the length from the forestay attachment on the deck to the mast.for sizing a headsail (jib/genoa) a 100% jib would have an LP (or approximately foot) of J, a #1 jib would have a 155% the length of J.
On upwind legs, the jib serves to direct the air around the leeward side of the mainsail to reduce pressure on that side, causing forward propulsion in accordance with Bernoulli's Principle. On downwind legs, it serves more like a mainsail, providing additional surface area to drive the boat. This is true of any jib sail on any boat.
If the mainsail is rigged for and aft it's most often called a sloop.
It depends on the type of vessel and how it is rigged. The smaller sail on a standard sailing boat is the jib or genoa
