The Main Topmast Yard:
The main topmast yard sheets (one each side) are of 0.75mm natural thread. The easiest method of rigging the sheet is to
work backwards, that is to say you will start at the belayed end and work to the sheet block. The sheet is belayed to the
head of the topsail sheet bitts (b25). Referring to Plan Sheet 8, the sheet then leads up through the inner 5mm block (on the
main lower mast yard), along the aft face of the yard and through the 5mm sheet block, at the stop cleat on the lower yard. It
then leads up towards the 3mm single clueline block on the topmast yard. A 3mm single block is seized in the end of the sheet
approximately 40mm from the clueline block.
The cluelines (one each side) are of 0.25mm natural thread. The standing end is made fast to the topmast yard as shown on
Plan Sheet 8. It then reeves through the 3mm single block in the end of the sheet, back up through the 3mm single clueline
block on the topmast yard, it then passes down through the main top lubber's hole and is belayed to the outermost pins of the
main topsail sheet bitts (b26).
The Main Topgallant Yard:
The main topgallant yard sheets, which also form the topmast yard lifts (one each side), are of 0.25mm natural thread. Again
it is worked backwards. Referring to Plan Sheet 8, a pair of 5mm single blocks are held in a length of 0.5mm black thread (this
is simply a length of thread with a block secured in each end which is then 'draped' over the topmast top bolsters), passing
between the second and third topmast top crosstrees, around the back of the topmast head and back down the opposite side so
that the blocks are positioned as close as possible below the topmast top crosstrees. The sheet/lift is belayed to the third, from
the front main lower shroud directly above the upper deadeye (b27). It passes up through the main top lubber's hole and
through the 5mm single block in a span around the topmast head it then passes out and down to the 5mm single lift/sheet block
on the end of the topmast yard, it then leads up towards the 3mm single clueline block on the topgallant yard. A 3mm single
block is seized in the end of the sheet approximately 20mm from the clueline block.
The cluelines (one each side) are of 0.25mm natural thread. The standing end is made fast to the topgallant yard as shown on
Plan Sheet 8 It then reeves through the 3mm single block in the end of the sheet, back up through the 3mm single clueline
block on the topgallant yard, it then leads down through the main top lubber's hole and belays to the outermost belaying pins
of the main jeer bitts (b28).
The Mizzen Topmast Yard:
The mizzen topmast yard sheets (one each side) are of 0.5mm natural thread. Referring to Plan Sheet 8, it is rigged as per the
main topmast yard sheet, but is belayed to the lower belaying pin in the mizzen mast pinrail (b29). A 3mm single block is
seized into the standing end approximately 20mm from the 3mm single clueline block on the topmast yard.
The cluelines (one each side) are of 0.25mm natural thread. The standing end is made fast to the topmast yard as shown on
Plan Sheet 8. It then reeves through the 3mm single block in the end of the topmast yard sheet, back up through the 3mm
single clueline block on the topmast yard, it then leads down through the mizzen top lubber's hole and belays to the centre pin
of the mizzen mast pinrail (b30).
