I have one more tidbit to add. Launch just after the last wave in a set. If you time it right, as the last wave backwashes it will help pull the boat out and give you some added initial momentum.

Where I sail we have a steep drop off and I keep my traveler centered and sheet out instead of traveling out. I want the ability to power up quickly only using only the mainsheet.

With the shallower beaches like Daytona where you have to go farther out before you can lock down rudders, you need to travel out a bit to use the mainsail to steer.
