Boards all the way up, go at a slight angle to the waves, so you ride the wave and don't get caught in the trough. If you go straight in, you'll drop off the wave and potentially pitchpole in the surf - you don't want to go there. Slide up on the beach with the wave, blow the sheets, hop off and immediately pull up far enough to get out the wave wash and into the wind. Put her up on wheels and Bob's yer uncle.
Let the rudders pop up on their own (new style castings) to maintain steerage all the way in or if you have the old-style castings, unlock (but don't raise) the rudders before you catch the last wave. Harder to steer, but it will save your castings.
It's a valid technique for getting almost any beach cat in through the surf on to a sandy beach.
Also if you are moving a good bit faster and think "I can jump this wave", depending on your beach / shoreline, there may only be 12-24" of water on the front side of the wave due to it actually drawing water back...... If you were to jump said wave you may damage hull, rudders and castings like Matt said.
