SHIP NO. 336 CONT.

Boom Braces (L) The middle sling on each boom arm has a long,
free end, apparently used as a brace. Starboard boom brace
lies on the deck beside deck house; port boom brace is made
fast on the starboard side, together with port yard brace (see
above).
Boom Lashing (M) A cross lashing which holds the boom to the
mast, (taking the place of metal collars on modern ships). Not
very clear in photograph.
TO MAKE SAIL: The stop around the yard and the boom (H') is
cast off. The halyards are hauled until the yard comes to the
mast truck (A). Stops (H) are cast off the sail which then
unfurls and falls to the boom. The foot of the sail is made
fast to the boom-ends with the sheet ropes (perhaps now furled
inside the sail). The spars are then trimmed around as
required to meet the wind by the braces (F) and (L).
THE RIG: The rig is the square sail, typical of the XVIIIth
Dyn. Its advance over that of the Middle Kingdom is shown by
the lacing of the sail to the yard only, and not to the boom
as well, as in the M.K.
