The Main Yard:
To start, referring to (Fig 017 & 018), assemble one tack, sheet and clue garnet strop assembly by tying together one 3mm
single block, one 5mm single block and securing the 0.75mm natural thread tack, with its toggle, through the loop.
The main yard cluelines (one each side) are of 0.25mm natural thread. The standing end is made fast to the main yard as shown
on Plan Sheet 8. It then reeves through the 3mm single clueline block (of the tack, sheet and clue garnet strop assembly)
positioned approximately 40mm directly below the standing end, back up through the 3mm single block on the main yard. It
then passes down and is belayed to the outer end of the main topsail sheet bitts cross piece (b31).
The main yard sheets (one each side) are of 0.5mm natural thread. Referring to Plan Sheet 8, the standing end is rigged to a
copper eyelet on the hull, just forward and level with the bottom sill of the aftermost gunport as shown. It then leads up and
through the 5mm single sheet block (of the tack, sheet and clue garnet strop assembly), back down and is belayed to the finger
and thumb timberheads (b32).
The main yard tacks (one each side) are of 0.75mm natural thread. The standing end should already be secured with a toggle to
the tack, sheet and clue garnet strop assembly. Referring to Plan Sheet 8, it then passes down, through a 0.8mm hole (sheave)
fore and aft through the chesstree and then leads through a 0.8mm hole (sheave) in the hull 5mm forward of the chesstree.
From here it is led aft and belays to the first cleat on the inner bulwark (b33).
The braces are the next stage. Attach all brace blocks as shown on Plan Sheet 5; they are then rigged as follows.
The Spritsail Yard:
The spritsail braces (one each side) are of 0.25mm natural thread. Referring to Plan Sheet 8, the standing end is lashed directly
to the main preventer stay, approximately halfway between the 'mouse' and the bowsprit. It travels down and reeves through
the 3mm single blocks held in a pendant (47mm long) on the end of the spritsail yard.
Two 3mm single blocks are held in a span around the main preventer stay, positioned 106mm from the top. The brace passes
up and through these blocks and passes through the inboard sheave of the fore 3mm double block held outboard under the main
top, they then run aft, along the underside of the top, and through the inboard sheave of the after 3mm double block held under
the main top. From here it travels down to the deck and is belayed to the main topsail sheet bitts, around the end of the cross
piece (75) (b34).
The Main Yard:
The main yard braces (one each side) are of 0.25mm natural thread. The standing end is made fast to a copper eyelet, painted
matt (metal) black, positioned above the aftermost cabin light, as shown on Plan Sheet 8. From here it leads up and through
the 5mm single blocks held in a pendant (75mm long) on the end of the main yard, back down and through the main brace
sheave block (51) from outboard to inboard, it then leads forwards and is belayed to the cleat positioned halfway along the
quarterdeck inner bulwark (b35).
The Main Topmast Yard:
The main topmast yard braces (one each side) are of 0.25mm natural thread. In order to rig the main topmast yard braces,
referring to Plan Sheet 8, a pair of 5mm single blocks must be held in a span, of 0.5mm black thread, around the mizzen mast
positioned directly above the crossjack yard. The blocks should travel forward and be held 30mm from the mizzen mast. The
standing end of the brace is made fast directly behind the blocks, to the 'legs' of the span. The running end leads forward and
through the 5mm single block held in a pendant (55mm long) on the end of the main topmast yard. They then pass back and
through the blocks held in the span (always portside to portside and vice versa) they then travel to the deck where they are
belayed to the quarterdeck breastrail (170) (b36).
The Main Topgallant Yard:
The main topgallant yard braces (one each side) are of 0.25mm natural thread. The standing end is lashed to the mizzen
topmast between the topmast cap and the trestletrees, as shown on Plan Sheet 8. The running end passes up, forward and
through the 3mm single blocks held on a pendant (33mm long) on the end of the main topgallant yard, it then passes back and
through a pair (one each side) of 3mm single blocks held in a span around the mizzen topmast head, directly below the
standing end of the brace, the blocks should be held 15mm from the mast. From here they travel down to the deck, through the
mizzen top lubber's hole passing aft of the crossjack, and are belayed to the quarterdeck breast rail (b37).
