Don't be shy at all. Most cat sailors are pretty down to earth and there's nothing we like to do more than to get even more people involved in our sport. I am always trying to get friends & coworkers to come down to the beach and go sailing. The best way to learn and try things out is to just go up to people and start asking questions. If there is anyone on the forum in the places you are going just ask and I am sure some will reply and help you out.
