IRC Thailand — Sun, 13 May 2012 11:10:34 +0000

Question about setting a furling headsail.

IRC Thailand — Fri, 06 Apr 2012 04:14:50 +0000

We often have questions about setting furling headsails. The IRC Rule for a single furling headsail says: "The boat has a complete headsail furling system". Can the sail be tacked on deck instead of to the furling drum and still be able to enjoy the rating credit?"

2011 Certificates now being processed.

IRC Thailand — Wed, 18 May 2011 14:49:09 +0000

Processing of 2011 certificates are now well underway with the first event of the new year, Sawadee.com Regatta - Samui less than 2 weeks away.

For yachts with existing 2009 and 2010 certificates, renewal forms are now available in either Word or pdf format from the download section.

For New Applications and yachts with certificates dated prior to 2009, new appliaction forms are available Here.

Please allow 28 days for processing.

If a certificate is required in 5 working days Expedited Processing Fee applies (fee x2)

Attention is drawn to: rules 22.2.2 (standard furniture removal) and 21.2 (rig/sail features). Any declarations should be made on the revalidation form or on a separate sheet/e-mail.

If your boat is rated with default sized mainsail widths (MUW, MTW, MHW) we strongly recommend that these are checked and advised at the time of revalidation in the Changes box. See Rule 21.5.4 regarding minimum sizes.

If you are a new owner, please check the last valid certificate carefully, since you are now responsible for the accuracy of the data and information. Check particularly specific items like the sail configuration, internal ballast, stored power etc. to ensure the boat is still in the same configuration.

Remember that if your last certificate was Endorsed and you wish to retain this, any change to data must be officially measured or weighed; or in the case of sails, verified by the sailmaker.
