It is some time since the ‘Rigging Manual’ was updated. The Class name needs updating. There were also some unintentional restrictions in the Manual (when read with the Class Rules). For example, on a strict interpretation, it would not have been allowable to adjust the Spreader angles or length. These have been corrected. If you spot anything, the Technical committee will be pleased to hear from you.
