The Technical Committee has discussed how to measure the Runner Cut as specified in IDNIYRA Official Specification F.2 When this specification was written, aluminum masts were common, and the rigging was always set up without side stay tension. The Technical Committee believes the intent of the words "To be measured with skipper in cockpit in sailing trim" is to have the skipper dressed in his normal racing attire including helmet, and lying in the cockpit in normal sailing position. In order to make repeatable measurements of runner cut as intended by this Specification the following methods should be used: a) Rigging should not be tight during measurement. The skipper must be allowed to loosen the rigging as required to relieve static tension. b) Sailor should be wearing normal racing attire, including helmet, goggles. etc. c) Mainsheet must be loose. d) The runners must be allowed to move. If on the ice, the boat may be pushed to allow the runners to seek a neutral position. If using a measurement fixture, the device must allow free sideways movement of the runners. e) The skipper should be in the cockpit in normal sailing position (lying in the cockpit with his shoulders against the seatback).
