@Bacho - I have a similar situation and was able to sail at F18 Americas with no real issues.
Jeff, all AHPC boats come with a cert. Either you or I can contact Jill for a copy. I also have a lot of certs that Mike sent me and it looks like I have certs for all the 2011 Alter Cup boats which yours is one. Please send me your hull serial number (it has your original sail#). If I have you're cert I'll update it and sign it. Cert transfer is $10 and stickers are $30 (if you're not already stickered). Please pay the fleet treasurer.
