Echoing a little what was said above, balancing the boat with the sails is the important part of getting through the surf - and only on the days where the surf is big and the wind is light is it really tricky.

It's important to steer with your sails since you will need to have some directional control before the rudders are fully engaged. With an onshore breeze, keep the jib sheeted tightly so that it keeps pulling the bows down. Sheet in the main gently and be conscious that it will want to head the boat head to wind when it comes in too far...it will need to stay pretty far out. Put a lot of twist in the main and leave the traveler about half way down. Sheet in the main as much as the boat can handle it....however, if you are making headway safely through the waves, don't sheet in the main anymore...be happy with that.

Oh! And with the enthusiastic sage words Gaulden Reed once told me before a Tybee500 start a couple of years ago. "Don't forget your paddle today, boys".
