As mentioned in John's book report keep the speed up. As you come into a mark for a downwind rounding try not to turn the boat too fast. You like to take kind of an large arcing turn. If you come to the mark while keeping about a boat length or more high of the mark you will be able to make this turn and not lose too much distance passed the mark. I like to ease the jib, a bit, first while the crew goes in to set up for the downwind, counteracting their weight on the wire. That should keep the boat more in control.

Keep your weight back. If there is something you need to adjust that requires any weight forward wait until you are settled on your downwind run. Everything is a bit calmer then.
