It was found that the Marblehead Certification Control Form/Certificate permitted the input of data for rigs with the height of the upper limit mark exceeding the maximum permitted by the class rules, 2160 mm. A revised form has been released that corrects this.

Roy Stevens, Marblehead Registrar for the MYA, has checked the register and identified a few boats that are affected by this. As their certificates were issued in error those certificates have been withdrawn by the MYA under A.10.2 (b) of the class rules. Roy will contact those who have a certificate that has been withdrawn.

What action the affected owners should take in the case of a boat with a withdrawn certificate

Assuming the certificate correctly recorded the size of the rig, the owner will need to lower the height of the lower limit mark until the height of the upper limit mark is equal to, or less than, 2160 mm. The height of the foretriangle height limit mark should be checked too.

Once this has been done an official measurer should complete a certification control form for the affected rig(s) and send it to the M class Registrar, Roy Stevens, who will issue a new certificate.

If it is not possible to lower the height of the lower limit mark the owner may have to lower the height of the upper limit mark on the mast which may entail shortening the luff of the mainsail. Again, please check the height of the foretriangle height limit mark too.

If you need to discuss this please call either:

Roy Stevens on 01642 724 211 or

Graham Bantock on 01376 570 583

Thanks,

Graham Bantock
Technical Officer, MYA.
