Evolving Mainsheet

After her restoration Shamrock's running rigging mainsheet consisted of 4 cm (1.5 in) manila rope with a 23 cm (9 in) double block and a 23 cm (9 in) single block with becket and a bulls-eye.

During the 1980s’ this was changed to two 23 cm (9 in) triple blocks, one with a becket and the bulls-eye resulting in more rope being required and such a complicated layout that the crew would have to use a model of the blocks to assist in the mainsheet reeving procedure. When not in use long bights of mainsheet rope were draped over the mizzen sail cover.

As the manila running rigging ropes are in the process of being replaced with Polyhemp, the opportunity is being taken to simplify the mainsheet by using only two 23 cm (9 in) double blocks, one with a becket and no bulls-eye which also means one of the deck eyebolts can be removed and a lot less rope is required. This layout also enables greater control of the main sheet with the bight running from the lower block and making it easier to deploy the mainsail to starboard or port. Replacement blocks have already been selected and are in the process of being renovated.

Shamrock's Slipway

With the delivery of the new rails for Shamrock's slipway due, the crew has used the time preparing the old rail chairs ready for re-use. This has mainly consisted of removing the old rusted-in securing screws with the aid of a large hammer and the clearing of any rust from the seat area. Replacement “Coach Bolts” are also being cut ready for the securing of the chairs to the sleepers.

Swans

After  two years of failing to raise any young, the pair of swans that normally nest in the mill creek gave Cotehele a miss this year. With their recent reappearance, along with five cygnets, the new nesting site they used, believed to be between Cotehele and Halton Quay, has obviously been a success.
