The driver boom and driver gaff should now be fitted as follows.
The Driver Gaff:
Referring to
Plan Sheet
5, make up the driver gaff as shown including the copper eyelet (180) at the throat of the gaff jaws
(139) and a 3mm single block lashed to the gaff approximately 55mm from the end. To the driver gaff, seize one 3mm single
block to the copper eyelet at the throat of the gaff jaws using 0.25mm black thread as shown on
falls (for the throat halyard) of 0.5mm natural thread are secured into the arse of this block at the same time.
The driver gaff jaws (56) are held in place by 10 parrel beads (186), on 0.25mm black thread. It is also recommended that the
gaff is secured by pinning it to the mast.
A 3mm double block is seized to a copper eyelet (180) on the main top starboard trestletree as shown (Fig 003), the throat
halyard (standing end currently in the arse of the 3mm single block at the throat of the gaff) can now be set up as follows. The
running end passes up and through the port sheave of the 3mm double block on the trestletree, back down and through the
3mm block at the throat, back up again and through the starboard sheave of the double block. From here the running end
passes down, starboard side, and is belayed to the foremost cleat on the inner starboard bulwark between gunports six and
seven (b43).
The gaff topping lift is of 0.5mm natural thread. The standing end of the gaff topping lift is made fast directly to the driver
gaff, approximately 10mm from the end of the gaff. The running end passes up and through the starboard sheave of the 3mm
double block secured to the copper eyelet (180) in the after face of the mainmast cap, back and through the 3mm single block
lashed 55mm from the end of the gaff, back up and through the port sheave of the 3mm double block. From here the running
end passes down through the lubber's hole in the main top, port side, and is belayed to the foremost cleat on the inner port
bulwark between gunports six and seven (b44).
Note: The driver gaffs on brigs were rigged to hoist and as such no vang pendants were ever fitted.
The Driver Boom:
Referring to
Plan Sheet
5, make up the driver boom as shown including the 3mm double blocks (one each side) lashed to the
boom approximately 100mm from the end.
Note: The boom itself should be positioned off centre to the port side to allow the topping lift to be shipped past the driver
gaff.
The driver boom jaws (38) are held in place by 8 parrel beads (186), on 0.25mm black thread and the driver boom saddle
(101). It is also recommended that the boom is secured by pinning it to the mast. The saddle is positioned 32mm off the deck.
The guy pendants (one each side) are of 0.25mm black thread as shown on
should be hooked, hook up, into the copper eyelets in the inner bulwarks just aft of the seventh gunports as shown, the falls of
0.25mm natural thread should be secured into the arse of these blocks at the same time. A tackle is set up between the 3mm
single block and the 3mm double block 100mm from the end of the boom and the running end is belayed to the cleat on the
inner bulwark, 30mm forward of the captain's cabin screen (b45).
The toping lift is of 0.5mm natural thread as shown on
approximately 10mm from the end of the boom. The running end passes up, port side of the driver gaff, and through the 3mm
single block seized to a copper eyelet (180) in the after face of the main mast, approximately 20mm below the tops. The
running end passes down, port side, toward the aftermost cleat on the port inner bulwark between the sixth and seventh
gunports. A 3mm single block should be seized into the end of the topping lift approximately 75mm off the deck. A 3mm
single block is hooked into the copper eyelet in the port bulwark just forward of the seventh gunport and the falls of 0.1mm
natural thread are secured into the arse of this block at the same time. A tackle is now set up between this single block and the
double block in the end of the topping lift and the running end is belayed to the aftermost cleat on the port inner bulwark
between the sixth and seventh gunports (b46). A small span of 0.1mm natural thread is now rigged between the boom and the
topping lift; it is positioned 50mm from the end of the driver and is secured to the topping lift approximately 40mm from the
standing end of the topping lift.
