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.
