If you can't find any other postings on the forums, here's a few pointers as I understand it.

Make sure you have at least some speed going into the tack. When turning the boat don't slam the tiller across, that will stall you, but make it a smooth turn. As you go into the turn you must let at least 2 feet of rope through the main sheet as if you keep the mainsail tight in it just keeps you into wind. As with the jib, keep it there for a while and let it backwind, this will push the front of the boat around. That should help you get through every time.

If you do get stuck, then push the sail out to get a bit of drive in the sail which will start you sailing backwards. Reverse the rudders which will bring the front around, once it's turned straighten up the rudders, sheet in and you should be OK.

Failing this, have a look at the numerous information on the web, I'd suggest looking at the learn to sail section at the website www.hobiecat.com to begin with.
