2007 Chief Measurer's report

Chief Measurer's Report to 2007 World Council Meeting

Since our last meeting in 2005 at Darwin the Tasar has undergone the most significant change in the history of the class - the introduction of Mylar sails. It is a credit to the class management and the Tasar community in general that this change has come about so smoothly, with such goodwill and so little upset.

Introduction of the Mylar jib involved an additional halyard and new fittings at the head of the sail. Our approach was to publish some guidelines and encourage the sailors themselves to develop the most effective way of hoisting the sail and adjusting the jib luff tension.

Over the next eighteen months a task will be to firm up and develop class rules to apply in this area. To this end I invite input into the debate from all Tasar sailors - is the setup we currently have the best available, or could a different approach yield a better result?

Introduction of Mylar sails revealed an issue with a fluttering mainsail leech in an early production batch. The problem was quickly addressed by 1) Interpretation 35 which allowed for appropriate repairs and 2) action by the sailmaker, Ian MacDiarmid.

A further issue to do with repair and replacement of broken jib battens has recently been addressed with Interpretation 36.

Both of these Interpretations, along with Interpretation 34 (allowing clam cleat keepers) will be submitted to this meeting for ratification at the conclusion of this report.

Moving on, at the WTC meeting at Darwin, Designer, Frank Bethwaite was asked to approve a specification change which would allow use of a swivelling cleat (Ronstan RF5 or similar) to secure the downhaul. This was agreed to and subsequently came into effect in December 2005.

Another issue that came to light again, also at Darwin, was presentation of some older wooden foils which had had inappropriate repairs completed and which now no longer complied with the required foil profile. Discussion with the Designer revealed a pre-existing diagram which provides section measurements against which doubtful foils can be measured. A copy of this diagram has now been forwarded on to all Regional Measurers.

Measurement for this World Championship has progressed smoothly with few issues needing attention. For this regatta we have tried to streamline the measurement and registration process by introducing a pre regatta measurement checklist. Key objectives for this process are 1) to reduce the time taken far regatta registration - high on the ISAF's wish list for International Classes, and 2) to shift the emphasis for class rule compliance back onto competitors. With further refinement we hope to see this process adopted for all future Tasar World Championships.
