Hull Registration Number .................................................

GENERAL NOTE TO MEASURERS

1 Measurements shall be carried out in accordance with the Equipment Rules of Sailing except where varied in the class rules.

2 The boat shall comply with all the class rules in Sections D, E, F, G and H even if some of the rules are not mentioned on the measurement form(s).

3 This measurement form may be used for up to three rigs and their sails. Cross out the numbers above for rigs and their sails which have not been measured. Ring the numbers which have been measured.

4 To have more rigs and their sails added to the certificate the official measurer shall measure the rigs and their sails and complete a new rig/sail measurement form. The rig/sail measurement form, together with any re-certification fee that may be required and the current certificate shall be sent to the owner’s certification authority.

MEASURER'S COMMENTS

If the official measurer has any doubt concerning the application of, or compliance of any part of the boat with the class rules he shall report it on the measurement form(s) before sending them to the certification authority and not sign measurement form(s) or sails.

DECLARATION BY THE MEASURER

I confirm that I have taken the measurements on this form, that the particulars on this form are correct and that, to the best of my knowledge, the boat complies with the rules covered by this form. I have stated above in MEASURER`S COMMENTS those points where I have any doubt concerning the application of, or compliance of any part of the boat with, the class rules whether or not they are covered by the measurement form.
