Check the boom/gooseneck drawings on p. 51 of the Hobie catalog:
http://www.hobiecat.com/sailing/accessories.htmlAfter raising the main, slide the boom on, but leave the outhaul line (at the main clew) loose. The top of the gooseneck assembly pins into the mainsail tack, then you slide the gooseneck into the mast track. Run the downhaul line (tied to the ring on the bottom of the gooseneck assembly) down through the opening in the center of the downhaul cleat (on the lower mast track), then back up through the ring for a (friction laden) 3:1 purchase. Downhaul as needed then cleat the downhaul line on the downhaul cleat. Now go set your outhaul.
If you're having trouble downhauling, go ahead and put the mainsheet on.... a little main sheet tension will help the gooseneck slide down. The TrenTec gooseneck bearing makes it slide better and helps minimize galling the track as well:
