Rule 6.103 and 6.104

The Technical Committee wish to draw attention to the new class rule 6.103 which comes into effect on March 1st, 2016. The rule which was approved at the last AGM in October 2015 in Paris limits the movement of the mast at deck level (see text and scheme below)

Sailors competing in regattas from March 1st, 2016 onwards are requested to ensure that their boats comply with this new rule. Each of the boat builders have developed a kit which can easily be fitted to existing boats. Please contact your builder for specifics.

To ensure compliance with the new rule, Race Committees, Juries and Measurers are requested to include a check of the mast movement at deck level in any measurement checks undertaken at regattas from March 1st, 2016 onwards.

Rule 6.103

A mark (made from metal or plastic plate) 50mm measured fore and aft and 20mm athwartships shall be fixed on the deck on each side of the mast opening, in such a position that the foreside of the mast shall not be outside nor be capable of being moved outside the limits of these marks. (see diagram on page 22).

Movement of the mast within these limits shall be restricted by filling pieces or bolts fixed in such a way that they cannot be removed while racing.

Athwartship clearance of more than 10mm each side is prohibited. Any filling pieces limiting athwartship movement to 10mm shall be fixed such that they cannot be removed with the mast in place. (Note: Any other filling pieces or chocks do not have to be fixed).
