International 2.4mR: 2.4mR boats are single-handed keelboats and are designed under the same rule as the 12m America's Cup boats. They are 4.1m long and weigh 260kg.  Their design allows the helm to sit amidships holding all the instruments for controlling the boat craft and navigating, at a distance roughly equal to that of the arms when outstretched.

Sonar: The Sonar class has a crew of three, a fixed keel, a length of 7m (23 feet), and a weight of 950kg. Sonar has three sails - main sail, jib, and spinnaker, but when used for Paralympics the crew just uses the mainsail and jib. The Sonar provides the option of sailing together with a crew of various disabilities and, because of its size and flexibility, allows many different adaptive aids to be incorporated into the boats to assist those sailors with more severe disabilities.

SKUD 18: The SKUD 18 is a two person keelboat. Sailors will be seated on the centreline for Paralympic events. The helmsperson can transfer manually and be steering with tillers, or be in a fixed seat on the centreline using a manual joystick, push/pull rods, or a servo assist joystick with full control of all functions. The forward crew can either be seated on the centreline, transferring manually, or on trapeze. The boats have a length of 5.8 m, a minimum weight of 380kg and three sails: one mainsail, one jib and one spinnaker.

Sail Identification: All boats shall carry on each side of its mainsail and on each side of the hull the country code denoting its national authority. Country codes will be applied at Measurement. No other sail numbers shall be displayed.
