F104 is a disparate collection of boats that rate 1.035 to 1.045 under SCHRS.
These boats are sailed 2 up with main, Jib and Spi.
I believe there are some other rules, but the basis of the group is the rating falls between 1.035 and 1.045 on SCHRS.
Does anybody know what those SCHRS ratings would be in terms of comparable Portsmouth ratings?
