Letting go the spring stay and topmast stay.

Next, the boom cable is attached to the mainmast to hold it upright as the shrouds are removed and its rigging lashed to the mast. When this is done, the mast will be lifted from its step and up through the decks, then lowered to its place on the deck. The same process is repeated with the foremast. (There are no photos of this process because it required all hand to complete.)
