Koos - you have a gift rating! For PHRF-NB the base rating for a boat assumes 155% headsail and spinnaker pole same length as J dimension. For a J/30 that equates to 144, although my OD certificate shows a base of 138 with no adjustments. The 138 base is consistent with a 144 base and adjustments of -3 sec/mile for oversize OD jib and -3 sec/mile for oversize spinnaker pole (J + 1 foot). The doublehanded certificate that I have assumes only the #3 genoa is used and the base is listed as 144 which is adjusted to 150 spinnaker, 173 non-spinnaker.

PHRF-NB applies adjustments per this document:
Cruising Headsail +6
Roller Furling +3
OD 163% Genoa (155 base) -3
OD Spin Pole longer than J dimension by 1 foot -3

For One Design, the base ratings are 138 non spinnaker and 155 spinnaker. Assuming since you have roller furling and cruising headsail, your rating is 138 + 9 = 147 spinnaker and 155 + 9 = 164 non-spinnaker

If you reported any changes to the OD configuration, the rating may also be adjusted. I never figured out why the base is listed as different on the certificate for OD versus a non-OD configuration, but the adjustments seem to be consistent when applied as a difference to the OD rating. You may want to send Pat Beausoleil (PHRF-NB Administrator) an email and see if she can send an explanation.
