Try an A class catamaran. If you aren't in love with it after sailing it then don't buy it.
I have owned and sailed a bunch of spinnaker equiped cats. After trying an A class cat, I have no desire to own or sail one anymore.

All that having been said, I enjoyed sailing the Tiapan 4.9 with a spinnaker when I had the chance. It sailed almost as nice as an A cat.
