My first cat was an H16 too, easy to rig and sail.
Now sailing the A I kinda miss the hobies easy rudder up system and no dagger boards to deal with on launch and landing. You can drive a Hobie up onto the beach and step off on dry land. With most others you have to do a soft landing walking the boat out of the water with hydrolic assist from the shore break until shes back on solid ground.
Most bang for the buck is a used race boat, Nacra, Prindle etc. Enjoy what ever you get thats why I do it.
