The AC45 catamaran.

Between the 2 main crossbars  span a rectangular, between the first crossbar and the jib a  triangular trampoline. The catamaran is steered with tillers. daggerboards on each hull reduce the drift. This boat is offered as a "one-design" package without the possibility of a major design change. The yachts are the same for all teams. Teams may modify the rig or equipment for experimental purposes, but may not use these changes in race. On the hull nothing can be changed. The package (hull, sail, etc.) is produced in New Zealand by the company Core Builders in Warkworth. For transporting the boats have to be dismantled within 24 hours and have to be be ready to sail again within 48 hours. You can lease or buy the catamaran From 2012, a standardized "wing-sail extension" is offered as an optional extras. This wing is a replaceable 4 m long mast extension with a square of about 8 m2. The extension is used in light winds. The midship rear-mounted S-shaped extension has the joke name "Christmas Tree" and bears a row of coloured signal lights. These are activated by radio and transmits coded instructions of the umpires. They will replace their support boats with the light bar.

As each catamaran the AC45 consists of 2 identical hulls, which are connected by two tubular cross bars. Midship is another bar, which ends at the bow into a jib boom and at the stern with the “Christmas Tree.” On this boom sits the wing with its front edge on a rotating platform. The at the front rigid wing is approximately from the center backwards divided into 4 flaps. Those are trimmed via cables. Two soft sails the genaker and the smaller jib are hooked on the the jib boom. From this bar a small pole ( old seaman called it „dolphin stroker“ and another one below the rotating plattform have been mounted downwards to support the load distribution of a lot of anchoring cables.
