We only do this when the wind is really blowing 25mph+ at the lake, because the marina and the sail shop are on both sides of the boat ramp, and I don't like the crunch of fiberglass against a dock.
I've also discovered that hanging the boom keeps the Main sail dry and I can put it into my sail tube right away.
I usually can sail straight to the ramp with full sails without any trouble, but hanging the boom with the main rolled up keeps it out of my way and keeps it dry on those hairy days!
