The board of governor's discussed the jib hanks at the 10 May 2012 meeting and as recorded in the minutes, "... Two members who previously measured in at NAs with hanks (Rotsky & Mather) will be grandfathered - proposed wording to be posted on website change. ..."
The wording proposed is the resulting action resulting from these minutes.
