Skiffs have more girl junior sailors then the entire catamaran junior fleet.
They have a west coast regatta circuit and are trying to build an east coast circuit. They have international junior rock starts already. They have many yacht club organizations behind them supporting junior high performance sailing.
The number of women teams in the last couple of US F18's and Tiger Championships..... maybe 1.
The interest of the ISAF women's committe in mulithull racing... much much less then match racing in keelboats and skiffs.
