Reading the Notice Of Race for the next Marblehead-Halifax race, I try to figure out if the J/30 complies with the modification of #3.04.2 of
ISAF OSR specified in the NOR section 1.2.3, that is:
1.2.3 OSR 3.04 Stability - Monohulls: -- Sub-paragraph 3.04.2 shall apply as follows:
(i) A yacht of less than 31 ft LOA in hull length:
(a) Shall have a minimum displacement of 3.0 tonnes (6,600 lb) and shall meet at least one of the following:
(b) Design Category A under ISO 12217-2 and an Angle of Vanishing Stability (AVS) greater than (130 - (2 x mass)) where mass is the minimum sailing displacement in tonnes, but always greater than 100°, or
(c) Minimum Royal Ocean Racing (RORC), STIX of 32, or
(d) Minimum RORC Stability & Safety Screening Numeral (SSSN) of 28, or
(e) Minimum ORR Stability Index (STBIX) of 110, or
(f) Class rules if those rules have been previously accepted by the Marblehead to Halifax Ocean Race Committee (MHORC), in which case 1.2.3 (i) (a) above does not apply.
(a) is much subject to interpretation - is that the actual displacement with crew in at the time of the start? - and I have no idea regarding the (b) to (f)...
Not that I feel the boat ready yet this year, but I have been slowly making upgrade to the boat with the idea to sail this race...
Thanks!
