A short topgallant mast is sent up like a topmast, the cross-trees got over in the same manner; and the fidded royal-mast is sent up like a long topgallant mast. TO RIG OUT A FLYING JIB-BOOM.--Ship the withe on the jib-boom end, reeve a heel-rope through a block at the jib-boom end, and bend it to the heel of the flying jib-boom, and stop it along, out to the end. Haul out on the heel-rope, point through the withe, put on the rigging, in the same order with that of the jib-boom; reeve the guys, martingale, flying jib, royal and skysail stays; rig out, and set up the rigging. The heel of the boom rests against the bowsprit cap, and is lashed to the jib-boom. The flying jib-boom should be rigged fully out before the fore topgallant mast is swayed on end. TO CROSS A TOPGALLANT YARD.--Seize on the parral and quarter-blocks; reeve the yard-rope through the sheave-hole of the topgallant mast, make it fast to the slings of the yard, and stop it out to the upper end. Sway away, and when the upper yard-arm has reached the topmast-head, put on the upper lift and brace; sway away again, put on the lower lift and brace, cast off all the stops, settle the yard down square by lifts and braces, and pass the parral lashing. TO CROSS ROYAL YARDS.--The royal yards are crossed in the same manner as the topgallant yards, except that in most merchantmen they would be sent up by the halyards instead of a yard-rope. If there is not a standing skysail, the quarter-blocks on the royal yard will be single.
