TA, to clarify with your diagram, the taipan with wings is 2.66m wide as the rules state that the measurement is taken from leeward hull. So I could put 16cm wings on either side.

Scooby_Simon, see your point of taking into account rig weight aloft as this would fall over the pivot point quicker in my taipan v viper example, but have we measured the extra force you able to exert through the lever effect v this force of the mast over the pivot. Would be interesting to see these calcs in the whole picture.
