Am I right in assuming from the class rules as they stand that the distance from the sheerline to the upper line of the lower black band is between 630 and 730mm ie approx 25 - 29"

Spot on Garry.  How is the rebuild project going?

GGGGGGG

The hull and re-decking is all complete and I am in the process of putting all the bits and pieces back - just about there actually.  I have the rigging to sort out hence the black band question.  Definitely on course to be on the water for the new season and planning the vintage events down south to tie in with holidays.
