Grad tuning tips - inboard sheeting

In recent years, it has become commonplace to move jib fairleads inboard to improve pointing. Historically, Graduates used fairleads mounted on the side deck, with the cleat positioned on the opposite (windward) side. Many methods have been devised to alter the effective sheeting position. The exact distance inboard will depend on personal preference, deck layout, and the cut of sails; as a starting point, the block should be positioned 23cm inboard from the shroud, and about 175cm from the stem fitting.
This shows a common modification made to a standard Wyche & Coppock Supergrad. The existing fairlead is used to control (via red control line) the athwartships position of the ratchet block. Additional lines (blue, just visible, and black) are required to control the height of the block. Shockcord is used to hold the block in place, and to stop tangles.
This shows a wooden boat with a similar setup, with perhaps more adjustment possible. The control lines are held by cleats. This arrangement does, however, limit the space available for the crew to sit, particularly in light weather.
These pictures illustrate more permanent solutions, involving some modification to the deck layouts of a GRP Supergrad (far right) and an Alpha. Note the jib is cleated on the leeward side, which some may find more convenient. The cut of the jib may cause problems; if the foot of the jib is too long (or the jib too low on the forestay), there may be insufficient distance between jib tack and the block.
For Sprinter GRP boats, moulded fairlead platforms are available from Butler Boats. These may well fit other deck layouts.
