Well in all honesty I would love to have a spinnaker for the Inter17 but I haven't found any great deals on one of those. Although there is one on the classifieds on here.

The spinnaker I am buying is a Hobie 18FA spinnaker. The hoist height is only one inch from what I orginally wanted and the spinnaker is in good shape. It will give me something to learn with until I can afford a boat made for spinnakers.
