my club now has the Portsmouth Ratings online on our site, but for one reason or another we don't have the rating for my Mystere 6.0 with spin (no wings), crew weight about 400 pounds. Where do we get this?

Catius in the Port- ratings there is a handicap formula and list for boats with equipement that normally is not class legal but may be used in the handicap formula. The Spi has a number that is deducted from the normal rating (M6.0 xl=64.0). That list you have is all over the charts the same boat has a different number M6.0xl ranges from 64.6-62.8 same boat both with wings.The TF16 goes from 65.9 to 61.3 is that from the portsmouth Handicap system or from the club?
