Return to the Forum List RL24 class rules sail sizes versus Australian Sailing tech committee sail sizes. | Hi all, I hope you find this information of some value. I contacted my sailmakers North sails regarding AS tech committee changes to the RL24 sail dimensions.
The tech committee have increased the RL24 handicaps using larger sail dimensions.
What this means is that in Open Trailable yacht races the RL24 can sail with BIGGER SAILS. Please find my corrospondence with North sails attached.

Email from Norths,
Hi Scott,
Cocko has asked me to put together a quote for some larger RL24 sails for you.
Please find Also attached our designers Overlay of Class Vs CBH Sizing for a visual look of the sizing changes.
I'm not 100% across what the rule change is, But let me know if there is anything I can find out for you.
Hope you are well.
All the best
Aaron.

Unfortunately you are incorrect. We can't use bigger sails in open events as they are governed by the AUSTRALIAN TRAILABLE YACHT AND
SPORTS BOAT RULE. Rule 12 says:
12.0
SAILS:
12.01 Sails shall be constructed and measured in accordance with the individual class rules.
12.02 If no class rules apply, sails shall be measured in accordance with the ISAF Equipment Rules
of Sailing in relation to sail measurement but shall not exceed the dimensions of the CBH
measurement factors. These measurements are provided for the majority of ATYSBR listed
boats in Appendix A - “ATYSBR CBH Measurements”.
I also did some calculations re the dimensions listed in the ATYSBR and, yes, if we could build our sails to those dimensions we could have WAY bigger than 20m2 .... but we can't.

| | TECH COMMITTEE MEASUREMENTS TAKE PRECEDENCE OVER RL24 CLASS RULES. | REPORT OF THE AUSTRALIAN SAILING NTYSB TECHNICAL COMMITTEE
Review of ATYSBR including Appendix `A` National CBH List
4th JULY 2018
//////////////////////////////////////////////////////////////
At this point the mediator Mr. Alistair Murray, gave his view on the current positions of both parties.
The pertinent points being:• The ATYSBR and CBH calculation must take a precedence over class rules, particularly as it
was fundamentally a measurement-based formula.
//////////////////////////////////////////////////////////
• The RL24 class would be gaining advantage over other more constrained classes by having
no limit on BLM and,
• It was unclear if the RL24 class had been performance adjusted historically.
12.0 SAILS:
12.01 Sails shall be constructed and measured in accordance with the individual class rules.
12.02 If no class rules apply, sails shall be measured in accordance with the ISAF Equipment Rules
of Sailing in relation to sail measurement but shall not exceed the dimensions of the CBH
measurement factors. These measurements are provided for the majority of ATYSBR listed
boats in Appendix A - “ATYSBR CBH Measurements”.
