Letter to NAs & Local Measurers by Graeme Harbour:
The purpose of this email is to try and bring everyone up to date on any measurement issues and to make sure we all adopt a common approach to undertaking boat measurement on new equipment and equipment inspection at championships.
….
*Boat length & width, this is hull and rudder gudgeons only, other fittings attached to hulls such as foot straps, inspection ports, external transom reinforcement etc. must fit within measurements. ISAF has confirmed this.

*Dagger boards after exiting bottom of hull must not go outside 2.3m rule or inside .75m from centerline rule in all positions until fully down.
I found a number of new boats at our Australian Championships that had the tips of “J” & “Z” boards outside 2.3 m just after exiting the bottom of hull. There is a diagram covering this aspect in Measurers’ Guidelines.

* Rudder winglets, again must fit the 2.3 & .75m rules. We found a number of boats in New Zealand outside 2.3 m and skippers were busy cutting wing tips off…

* Cassette type dagger board cases. Unlikely to be seen but keep in mind that cassette does not need to be fully engaged in hull for 2.3m & .75m measurements to be taken…
