Lighter Tornado Sheeting Systems

Tried and Tested Lighter Tornado Sheeting Systems

The Tornado Class listened closely to the test sailors at the ISAF evaluation in Santander and we are now presenting our tried and tested smart sheeting system to reduce the loads of the gennacker and mainsheet.

We were especially interested in the comments from the women in Santander and their views about how they really want to have a sporting challenge at the top level of sailing. They don't want a boat which is easy to sail, they want a challenge and a boat they have to train for.

At the helm no women had any problems and some of the Ladies were winning the practice races easily. In a matter of minutes they were familiar with the boat and brought it up to the maximum speed. They commented saying that they really noticed the difference and the high quality of the Tornado over the other boats at the evaluations.

While crewing some said it was easy with the Gennacker and Mainsheet, some others said it was too hard to handle the sheet loads. It was great to get this feedback and comments from the sailors because for us these loads are normal and we have developed techniques to handle the Tornado sheet loads.

The class believe that if a boat is too easy to handle, it’s does not deserve to be at the top sporting event the World sees. The Olympics are for the very best Athletes and it should be a sporting challenge which you should train for. Class treasurer Nahid Gaebler (Tornado crew, 44 years old, World champion) is a normal woman with no special fitness training, and she easily handles the sheet loads of the Tornado in up to 30knots of wind (see the World championship Final Day 2011). The Tornado Class have seen a dramatic rise in mixed teams since 2010 and continues to grow, 80% of these teams have female crews.

The Tornado Class take the comments of the evaluation sailors very seriously and we have been re thinking about options to face the critics. We would now like to present a tried and tested solution after discussions with our Tornado membership and technical partners Harken and Ronstan.

We propose to change the sheet from the Gennacker (which is actually direct 1:1 with two automatic ratchets) with an extra block and make it 1:2.

Also the Mainsheet (which is actually 1:8) we can change with only one extra block to 1:12.

This way we make it 50% easier on the Gennacker sheet and 33% easier on the mainsheet without having too much extra sheet length. This is also a system used by team DEN during their Olympic Campaign, the crew had a shoulder injury and was not able to handle the sheet loads.
