Well, I had a go at a windy "landing" when we got Arosa out of the water at the end of last season. I had to go around twice before I got it right... Without a bow truster, the main focus is timing. Have you ever seen aircraft on final approach with a good crosswind? This is exactly the same: Keep the bow aligned with the trailer but heading slightly into the wind. In the last few seconds before you hit the trailer, you have to pull straight. It's not as scary as it sounds as you can always back out. Do not be afraid to do so however, no matter how many people are watching!
Good luck practicing, and keep it slow...
