110 Class President, Josh Hill, has proposed a new set of sail measurement rules. The proposed rules are published below. All are welcome to comment and make suggestions either to Josh directly, or in the forums or 110 class Facebook page. Here are the rules:
SAIL REGULATIONS
ARTICLE I
1.0 GENERAL
1.1 Purchasing of Sails:
Two suits of sails may be acquired in the first calendar year of the yacht's life, and one suit each year thereafter, not to be cumulative. In the event of the loss or destruction of a sail during the year in which it was purchased, such sail may be replaced within the year, when evidence substantiating the loss is considered justified by the Fleet Officers.
1.2 Dating of Sails:
Sailmakers shall indelibly mark in approximately 1" characters, at tack, the month and year of sale of each sail. Sails submitted for measurement without having a sailmaker's date shall be assumed to have been acquired in the current year, unless it is obvious that they were acquired during an earlier year.
1.3 Royalty Fee:
All sails not previously stamped with the date and fleet number from a Class sanctioned regatta will require the owner to pay a $5.00 Royalty Fee for each sail not so stamped. The Royalty Fee collected shall be forwarded to the Class Treasurer.
1.4 Fleet Competition:
It is recommended, but not required, that sail dimensions be initially controlled at the fleet level. To this end, each fleet should require that all sails be measured before being used in fleet competition.
1.5 District Competition:
For District Championship competition, sails shall conform to the regulations set forth below. At the option of the host fleet, sails shall be measured prior to competition or such measurement may be waived on the basis of fleet measuring according to Section 1.4 above.
1.6 International Championship Competition:
Sails shall be measured and inspected immediately prior to International Championship Regattas, for conformance with the following regulations. Sails that are in compliance shall be legibly marked by the measuring committee, and only such sails shall be used in competition. Sails may be re-measured at any time during the regatta, at the option of the measuring committee, but retroactive disqualification as a result of the such re-measurement can be imposed only in the case of intentional concealment of information during the initial measurement or subsequent willful modification.
