A24 IRC rating.

guillainevib 9:14pm, 11 November 2009
Anyone got any idea what sort of rating an A24 has under IRC? I will probably get mine rated for next year, but I am curious to know roughly where she will sit.
Cheers,
Nicki

Hi

Found this site which might help.

www.petestack.com/sailing/apps/corrected.php?name=A24+FIN...

For a Fin A24 the PY is 1079 when you mess around with IRC rating over an hours race the IRC shows as 0.927


Boat Rating Elapsed

Hi guilainevib,
Both Scarlet O' Hara and Eole have 2009 IRC numbers. We are both fin keels, Scarlet is .801 and Eole is .807 due to having a larger roach on the mainsail and being younger. My present set of kevlar sails have been cut for the IRC rules as they will penalise heavily for oversize sails. These numbers make us competitive against GK24'S but we struggle against Hunter Impala 28's. For correct sail dimension sizes contact Denzil at Stephan Ratsey sailmakers, Neyland.

Thanks Will, .801 is even better. Any chance you could give me some idea of the various dimentions you gave RORC?

Hi Nicki,
you can download the dimensions required from the IRC website, there should be a picture of a sloop with sails on with diagrams of where to measure. Another thing i remember from Merlin when she was in Llanion yard, (my friend nearly bought her) is the very unusual keel shape, it looks like somebody in the past has filled in above the bulb to make it straight which is the first i've seen, they ask for keel shapes so that may make a difference but probably in your favour, by the way hope you have still got the curtains the previous owners wife lovingly made for Merlin.

Hi John,
Thanks for the info. I've got this years' IRC yearbook and other guff so I should be OK. Interesting what you say about the keel because I have never seen one like it on an A24. To be honest it caused me some grief at first as I thought it would not be a s stiff as the bulb keels. I had not thought about it having been filled in. On the subject of curtains, there are now none. None came with the boat when I bought her, and, to be honest, more moisture-wicking cotton in a boat is just not my thing. :-) were they a work of art?
Cheers,
Nicki
