Designed in the UK by Rodney March, the 20-foot-long Tornado was developed in 1966 as the Olympic catamaran for the '76 Games in Kingston, Ontario. Its two long hulls and 25.2 m square (272 sq. ft)of sail area allow it to accelerate to hair-raising speeds of 15-20 knots, making it the fastest of the Olympic-class boats. With the recent addition of double trapezes, a 25 m sq.(270 sq. ft.)asymmetrical spinnaker, and carbon rigs, the turbo-charged Tornado carries a crew of two at offwind speeds of up to 30 knots. Known for its innovative one-design racing, the Tornado has long been considered an almost perfect boat. tornado-sailplan.gif

10:1 Carbo Mainsheet System

Tornado mainsheet systems can be installed inside the boom or mounted externally. Internal 9:1 cascaded systems work, but problems are difficult to fix. Most sailors prefer a 10:1 external non-cascaded system because it's easily accessible and jam-ups can be fixed on the fly.

Cunningham,16:1 Double-Ended

The trimmer can play this powerful double-ended system from either side of the boat, tensioning hard upwind for boatspeed or easing for offwind power.

Self-Tacking Jib, Cascaded 4:1

The 4:1 self-tacking jib provides simplified boat handling, allowing crew additional time for fast wire-to-wire tacking. Upwind in light air, the traveler car is positioned near the middle of the track. As the wind builds, the car is eased to maintain speed and stability. Downwind, the trimmer plays the sheet to adjust sail shape.

2:1 Mainsheet Traveler

This simple system features a split line that dead-ends on two eyestraps to create one control line that brings the car to the center of the traveler track from either side of the hull.
