Estimated reading time: 1 min

Ten Rater (10R) is not limited in length and have overhangs beyond its waterline endings making them light, sleek, and fast. This IRSA rule is based on the 1887 ‘length and sail area rule’ which allows short waterline length boats to have a big sail area and longer LWL boats have smaller sails. It is an ‘open’ rule with great freedom to develop design and construction, particularly in rigs and sail plans.

10R Rules Proposed Update – MYA Tech Team Response – Jan 2016

During 2015 the IRSA technical committee worked on updating and revising the 10 Rater class rule.

These updates and changes to the class rule were presented to the MYA for comment in December 2015.

Comments were requested from all MYA members and there were some very useful comments made by those interested in the class who responded. There has been a lot of correspondence about this class and some of these letters are included in the set.

The MYA’s concern was that having had a problem with measurement at the 2013 National Championship, a report was done outlining the problems in discussion with Jon Simpson at RSD and all but one of these practical suggestions had been ignored and now are not being followed up.

The MYA response was discussed and coordinated by the MYA Tech Team with others and input into the draft rules as a comment in the margin by the MYA Technical Officer, Roger Stollery.

The official IRSA response to the MYA comments by Graham Bantock is included in this 10 Rater class set of documents.
