The driver boom and driver gaff should now be fitted as follows.
The Driver Gaff:
The driver gaff is held in place by parral beads, a throat halyard and a peak halyard.
Use 12 parral beads secured in position with 0.25mm black thread.
The throat halyard is of 0.5mm natural thread. Using Plan Sheet 17 & 18 for reference, one 5mm double block is secured to a
copper eyelet on the top of the driver gaff throat and a second 5mm double block is secured to a copper eyelet under the
mizzen top (starboard side), (Fig 042), and the falls are secured to the arse of this block at the same time. A tackle is set up
between these two blocks to hold the gaff at an angle that positions the outer end directly over the transom, the jaws should be
bevelled to sit flush against the mast when the gaff is at the correct angle. The running end passes down to a 5mm single block
attached to a copper eyelet into the poop deck (starboard side of the mizzen mast, in line with belaying cleat) and belays to the
starboard, foremost medium cleat on the poop deck (b70).
The peak halyard is of 0.5mm natural thread. The standing end is made fast to the end of the driver gaff as shown on Plan
Sheet 17. It then passes through a 5mm double block attached to a copper eyelet in the aft face of the mizzen lower mast cap, it
then passes across and through the 5mm single block lashed to the driver gaff as shown. Back through the double block at the
cap and down through a 5mm single block attached to a copper eyelet into the poop deck (port side of the mizzen mast) and
belays to the port, foremost medium cleat on the poop deck (b71).
A pair of 3mm single blocks tied in a span are put over the end of the driver gaff next (for the mizzen topmast yard braces).
The mizzen topmast yard braces are now rigged of 0.25mm natural thread. The standing ends can now be made fast to the end
of the driver gaff. The running ends then reeves through the 3mm single brace blocks on the mizzen topmast yard and back
down, through the two (one per side) 3mm single blocks tied in a span to the end of the driver gaff. They then belay to the
outboard cleats of the three cleats on the inboard face of the taffrail (b72).
A pair of 3mm single blocks are now tied in a span around the end of the driver gaff (for the mizzen topgallant yard brace) as
shown (Fig 048).
The mizzen topgallant yard brace is now rigged of 0.1mm natural thread. The standing part is made fast directly on to the yard
arm (there are no brace blocks). It passes down through the 3mm single blocks (one per side) tied in a span to the end of the
driver gaff and down to the poop deck where it belays to the middle of the three cleats on the inboard face of the taffrail (b73).
The vang pendants of 0.5mm black thread are now rigged. Measure the length of thread required (approximately 250mm total).
At the centre of the vang, throw a clove hitch over the end of the driver gaff. Tie a 3mm double block into each end
(approximately 120mm from the end of the driver gaff). A 3mm single block is attached with a rigging hook to a copper eyelet
in the first curve of the taffrail capping as shown on Plan Sheet 18, the falls of 0.25mm natural thread are tied into the crown
of this block at the same time. A tackle is set up between these blocks and the running end belays to the inboard of the three
cleats on the inboard face of the taffrail (b74).
A 3mm single block is now tied to the copper eyelet in the end of the driver gaff for the signal halyard of 0.25mm natural
thread. Each end of the halyard belays to the cleat on the inboard face of the taffrail, outside the starboard inner transom knee,
above the flag lockers (b75).
The Driver Boom:
The driver boom is held in place by parral beads and the driver boom saddle.
Use 12 parral beads secured in position with 0.25mm black thread.
There are a pair of horses on the driver boom which run from the end of the driver boom extending to just in front of the comb
cleat on the driver boom. The horses are formed from overhand knots approximately 8mm apart.
The guy pendants of 0.25mm black thread go over the end of the driver boom next in a similar manner to the driver gaff vang
pendants. Tie a 3mm double block into each end (approximately 75mm from the end of the driver boom). A 3mm single block
is attached with a rigging hook to a copper eyelet in the top curve of the taffrail capping (approximately 10mm in from the end)
(position shown on Plan Sheet 18), the falls of 0.25mm natural thread are tied into the crown of this block at the same time. A
tackle is set up between these blocks and the running ends belay to cleats approximately 5mm in from the eyelets holding the
3mm single blocks on the taffrail (b76). The boom itself should be positioned off centre to the port side to allow the ensign
staff to be shipped.
The toping lift of 0.5mm natural thread is now put over the end of the driver boom with a clove hitch as per the vang pendants
on the driver gaff. They run upwards and forwards to a pair of 5mm single blocks (one per side) in a span under the lower
mizzen mast cap. The running end then passes down outside the lower mast 'top' (between the second and third topmast
shrouds) and a 5mm double block is seized in the ends approximately 40mm below the lower mast 'top'. A 5mm single block
is hooked to a copper eyelet on the mizzen channel (position shown on Plan Sheet 18), the falls of 0.25mm natural thread are
tied into the crown of this block at the same time. A tackle is set up between these blocks and the running end belays to the
mizzen circular fife rail (b77).
The driver boom sheets are rigged as follows. A 3mm double block is tied to the iron horse between the inner transom knees, a
second 3mm double block is lashed to the driver boom within the comb cleat, and the falls of 0.25mm natural thread are tied
into the arse of this block at the same time. A tackle is set up between these two blocks and the running end belays to the small
cleat on the starboard inner transom knee (b78)
The ensign staff should now be shipped.
