A single masted boat is a sloop or a catboat.
It is a "sloop", said to be "sloop-rigged".
Sloop
The vertical pole is called a "Mast". The horizontal poles (on 3-masted ships for instance) are called "Arms" or "Yardarms".
a "one masted vessel" is a boat with a single mast, or a large metal/aluminum piece standing vertically in the boat. the mast always holds the main sail of the boatthere are many one masted sailing vessels in the worldsome include ::-J24-Tartan 28-Snipe-420-Laser-505-Lightening-Etchell-Viper-470-49er-29er-Sonar-Star-I420and that's just a handful! good luckAnother answer:If the sails are rigged fore and aft, a one-masted sailboat is usually a sloop or a cutter. I am not aware of the name used for one-masted square or lateen rigged boats.
It could be either a "ketch" or a "yawl".
The aftermost sail in a multi-masted boat is typically the mizzen, but in some rigs can be called the spanker as well.

This could be a sloop (main + jib), a cutter (main + jib + foresail), or a cat boat (main alone). There are many variations.
