Sorry you didn't get a quicker answer to this. Did you buy the boat?
As to what to look for, look for stress cracks and soft spots!
Also take a careful inventory of all the rigging, print a rigging guide from the hobie website so you know what is needed to rig. Unroll the sails and inspect. The small easily forgotten parts are all expensive to replace and can add up quickly if they are missing.
Let us know how it went!
