I've contacted SISA and am looking forward to sailing with them in the spring. Sailing is done here for the season and will start up again in March, although I may get out sooner. I've also been to Boise Marine, made it there on day 3 after moving here. They have a few things, will likely get more in the spring. It appears SISA has about 80 members and according to race results, have H16, TheMightyHobie18, H17, Nacra and some Prindles. Looking forward to sailing, racing and exploring the lakes around here.
I moved from the Gorge and sailed there extensively. Windsurfing is epic there, but just got boring after a while. I needed a mental challenge and cat sailing provides it. Any other NW sailors out there that want to meet sometime, just email me!
