There are TWO (2) different types of Spinnaker measurements.
MAX GIRTH - used in calculations for Symmetrical Spinnakers
MID GIRTH - used in calculations for Asymmetrical Spinnakers
We suspect that some Symmetrical Spinnakers have been rated using the MID Girth in error.
MAX GIRTH - is defined as the symmetrical spinnaker maximum girth. With the spinnaker folded in half, this is 2 x the maximum width of the sail measured from the center/fold of the sail to the luff and leech.
MID GIRTH - is defined as the Asymmetrical spinnaker mid girth, measured mid luff to mid leech under moderate tension.
