Specifications and Technical Restrictions, Revised January 2014


All drawings are to be read in conjunction with By-Laws Part B as they take precedence over the Plans, Measurement Forms and the Class Drawings. Any interpretation shall be made by the Australian Sharpie Sailing Association.


From the ASSA Constitution – By Laws Part B

“The Association shall be bound by successive ban periods which shall prevent it from changing the Specifications and Technical Restrictions of Class during such ban period. The duration of a ban period shall be three (3) years or such other period as shall be determined from time to time by the Association.

Records to be kept of all Items During Ban Periods – A record shall be kept, separate from conference minutes, of all items of equipment and alterations to specifications and technical restrictions not eligible for discussion at any one Annual Conference or Special Conference because of the ban period so that such items may be brought up for discussion at the expiry of each ban period. The Australian Secretariat shall six (6) months prior to the end of each ban period circulate to each Member Affiliate advice of the conference at which the relevant ban expires.”

The current ban period is in effect from January 2020 – January 2023.

Discussions for new changes will occur at the conference of the 2022/23 Nationals.
