Measurement Matters

Following unanimous agreement of the AC 32 "Competitors" (all Challengers and the Defender), ACC Technical Director Ken McAlpine (AUS) has issued two amendments to the AC Class Rule. Amendment No. 4 bans the use of masthead sails in the pre-start. Amendment No. 5 clears up confusion over the use of staysails when a spinnaker is not set, e.g., when the yacht is taking a penalty or the spinnaker has blown out.

Also, the Measurement Committee chaired by Mr McAlpine has issued Public Interpretation No. 31 concerning backstays.
