I sail "Hotel Charlie" (HC520) out of Melbourne, Australia.
I understand there are two versions of the Cal 14. Mark I has a shorter cockpit (and longer cabin), and the Mark II is vice versa.
You can definitely get a spinnaker for the Cal 14.
I'm glad to see you're excited about the boat -- it's pretty good isn't it?
