Well standard practice overhere.

The F18 and F20 guys even step their masts when the boat is still on the trailer. They drop the mast when the boat is first set on the trailer. The leave all stays attached and even the spi pole stays on the boat and hang in its own rest that is just below the one for the mast. This way they can rig when coming from the trailer very quickly. Thay however have one man on the trampoline lifting the mast up with the second guy only helping in the first meter or so. And they raise 21 kg masts (45 lbs).

I'm about to go for the same setup method.
