Section 6 Rig behaviour trial

6.1.1 The rig behaviour at sea is to be witnessed by an LR Surveyor.

6.2.1 The expected behaviour of the rig when fitted to the vessel is defined by the manufacturer. The manufacturer is to provide predictions for key parameters such as heel angle, mast compression, loads in stays and loads on sheets for a range of weather conditions as may be encountered during the rig trial.

6.2.2 The rig behaviour trial is to include:

• 3 sailing conditions described in the rig operations manually, typically covering close hauled, reaching and running conditions.
• Transition between the sailing conditions.
• The process of setting, reefing and changing of sails in accordance with the procedure.

6.2.3 Observations made during trials are to focus on agreement between predicted condition and actual performance, as well as the transitions between conditions.

6.3.1 Two copies of the trial schedule and observed behaviour, signed by the Surveyor and Builder are to be provided on completion of the trial. Once copy is to be placed on board the vessel and the other submitted to LR.
