Sorry to be misleading. I raise the mast in the parking lot then launch the boat and raise the sail on the beach. I was trying to describe the time for rigging and it is a 2 step operation.
It would be difficult to raise the sail on the water. In an emergency I guess you could raise the main and not clip the "slug" on the top of the mast. The jib could be raised but getting enough tension on the shrouds would be a little more difficult.
