Wouter - Mark is referring to the ISAF rule.
I hope that if they continue with the rule that they choose to reword it because I think that it can be interpreted it to mean that our current hook and ring equipment still qualifies...or at least, it's too generic to really indicate what DOES qualify.
40.2 A trapeze or hiking harness shall have a device capable of quickly releasing the competitor from the boat at all times while in use.
