The yawl (from Dutch. Jol ) is a sailing boat, it is similar to the ketch, only available here, the mizzen mast, which is also called drivers mast outside the ( construction ) water line and is usually much shorter ( max. 50 % of the mainmast ) than that of the ketch. The Besanschot is often performed due to the very far aft mizzen mast standing on a tail boom. Yawls usually have a more elegant lines and rigging as ketches, as the main mast further aft and can stand more space is available for headsail. Your mainmast, as with the ketch 7/8-, topp or be kuttergetakelt.
In practice serving the mizzen on a ketch mainly for propulsion, on a yawl mainly to balance trim the sail center of gravity. Therefore, the mizzen, as compared to ketch also be smaller, the greater bulk. The mainsail of a yawl has a similar area as the mainsail of a sloop usually comparable.
The yawl rig was originally developed for fishing boats. A good example of this was the Salcombe yawl, a traditional small fishing boat, which was built in Devon. In its heyday, the rig was mainly in single-handed sailors popular, such as Weltumseglern as Joshua Slocum and Francis Chichester, as yawls can be trimmed to even for smaller wind variances to follow a predetermined compass heading. Modern self- control equipment and navigational aids have made this property less valuable. Another reason that yawls today are rather rare, is the displacement of the yacht stern by the non- compatible with the yawl concave mirror rear, athletic, because it allows a higher hull speed, practically, because the inclusion of floating people or exceed the dinghy at a transom with swim ladder is of course much easier.
Ketch and Yawl is also known as 1 ½ - master.
In the illustrated example, the yawl is kuttergetakelt because she drives more than one headsail. And she has a fractional rig ( it is " 7/8" - rigged ). It also goes high or Bermuda sail. The aft mast ( mizzen ) leaves no forestay, but he has a Jumpstagspreize and jumps days.
