How to use the mainsheet swivel jammer?

Here are a few recommendations for the use of the mainsheet swivel jammer on a Tiwal sailing dinghy:

  • Keep the sheet in your hand so that you can release it from the jamming cleat quickly in the event of a  strong gust of wind, imbalance or some unexpected event. 
  • If you happen to capsize, remember to release the sheet from the cleat before righting the boat. If the boat has completely overturned, do not go under the boat to release the sheet. You must grab the end of the sheet by extending your arm under the hull. 
  • Be careful, as the sheet can accidentally get caught in the cleat during a maneuver, on land or on the water. 
  • The cleat allows you to sheet in easily, but sometimes too much: the feel of trimming the sail is reduced. For example, if your boat is stiff at the helm or if it isn’t moving forward, you may have over-sheeted the sail. Remember to shock and don’t forget to accompany your changes in trajectory by adjusting the sheet. 

The use of this jamming cleat requires experience and a certain level of technical skill. 

For safety reasons, we recommend that children are not allowed to use this cleat. The same applies to beginners or occasional sailors.  

The mainsheet swivel jammer is optional on the Tiwal 2, 2L and 3 models. The standard fittings on these boats are designed for maximum fun, sensations and safety. 

The mainsheet swivel jammer is part of the standard equipment on the Tiwal 3R and 2XL models in accordance with the power of their sails.
