Hi there,It’s my first time entering doing Hamilton Island Race Week with my boat and I was wondering if anyone knew what obligations there are for the Cat 5 compliance.I know what the Cat 5 standards are but do I need to get my sailing club to sign off on it and upload the certificate somewhere for HIRW?Or is it enough that I go through the list and make sure everything is in order?Do people come around and audit your boat at HIRW or is it just implied that you’ll have it sorted?Regards, Christian Email: Given email is not valid Please enter an email.
