Smack, after all this, I still don't see why anybody would include lying ahull in their repertoire. It's known to be uncomfortable (at a time when you really need to eat or sleep) and dangerous. There are two alternatives (stick with step 2 if you're confident your sails can take it, or move on to step 4), each of which is more attractive than lying ahull. So why ever do it?
