I will ping our Australia facility for you... see if they can answer any additional questions. You can also access their site directly at

The Hobie Pacific is an older design from Hobie Cat Europe. Not one we are planning to build in the USA.
The Getaway sail design (batten layout) has always been the same here. Hobie Cat Europe builds their own sails for our Getaway hulls, so perhaps they have something different you may have seen.
Spinnaker? Due to the forward trampoline and low bridle wires, we have not developed a specific spinnaker for the Getaway. The Hobie 16 spinnaker set is shown in these forums to work. There are many threads on how to adapt it.
