A yawl is a type of boat. The term has several meanings. It can apply to the rig (or sailplan), to the hull type or to the use which the vessel is put. As a rig, a yawl is a two masted, fore and aft rigged sailing vessel with the mizzen mast positioned abaft (behind) the rudder stock, or in some
2. A mizzen staysail is an occasional lightweight staysail on a ketch or yawl, set forward of the mizzenmast while reaching in light to moderate airs. [2] 3. A mizzenmast is a mast on a ketch or yawl, or spritsail barge. Its positioning afore of abaft the rudder post distinguishes between a ketch or a yawl.
Rudder post and mast placement defines the difference between a ketch and a yawl, as these two-masted vessels are similar. Yawls are defined as having the mizzen mast abaft (i.e. "aft of") the rudder post; ketches are defined as having the mizzen mast forward of the rudder post.
Ketches are similar to a sloop, but there is a second shorter mast astern of the mainmast, but forward of the rudder post. The second mast is called the mizzen mast and the sail is called the mizzen sail. A ketch can also be Cutter-rigged with two head sails.
A ketch is a two-masted sailboat whose mainmast is taller than the mizzen mast (or aft-mast), [1] and whose mizzen mast is stepped forward of the rudder post. The mizzen mast stepped forward of the rudder post is what distinguishes the ketch from a yawl, which has its mizzen mast stepped aft of its rudder post. In the 19th and 20th centuries ...
AAW An acronym for anti-aircraft warfare. aback (of a sail) Filled by the wind on the opposite side to the one normally used to move the vessel forward.On a square-rigged ship, any of the square sails can be braced round to be aback, the purpose of which may be to reduce speed (such as when a ship-of-the-line is keeping station with others), to heave to, or to assist moving the ship's head ...
This contrasts with a ketch or a yawl, where the after mast, and its principal sail, is clearly the smaller of the two, so the terminology is (from forward) mainmast and mizzen. (In a yawl, the term "jigger" is occasionally used for the aftermast.) [7] Some two-masted luggers have a fore-mast and a mizzen-mast – there is no main-mast. This is ...
Length between perpendiculars – The distance between where the forward part cuts the waterline and the rudder post of the ship. Length Overall (LOA) – The maximum length of the ship between the ship's extreme points; important for berthing purposes. Length at Waterline (LWL) – The ship's length measured at the waterline.
