CIRCULAR LETTER

BOOM

April 10, 2014

Current Rule

36. Boom shall be essentially straight, and shall not be tapered nor have lightening holes. The boom ends may be cutoff with a maximum angle of 45°. The height of the boom at either end may be reduced for access to blocks or boltrope.
Only one boom may be measured during a regatta unless irreparable damage has occurred.

It has been requested how much the boom height may be reduced. Having no specific measurement, the IRC decided as follows:
• The fore end of the boom slot may be reduced man 350mm from the front edge;
• The aft end of the boom slot may be reduced beginning from the aft side of the band.
The rest of the rule remains unchanged.
