1. Put forestay parallel to the mast. Mark the top of black band on mast on forestay. Return forestay to deck fitting.

2. For medium and heavy conditions measurement from mark to deck should be 122 cm. For light conditions 120 cm.

3. The measurement for mast and forestay positions is taken in a straight line between the station marks i.e. station 4, from Port to Starboard.

4. Upper and lower shroud positions are also taken from station 4, at an angle.

Rig Tension and Mast Set-up

Set-up of the rig:

1. Put the forestay on 121 (see figure 2)
2. Using a Loos model PT -2M, put 20 on the uppers and 5 on the lowers.
3. Put the tension gauge on the forestay.
4. Pull on starboard runner, until forestay tension is 30.
5. Mark the through deck position of the runner with tape.
6. Do the same exercise on the port side, (steps 4 & 5).
7. As a check, when pulling the runners just tight, the measurement from the tape mark to deck should be 15 cm.

For light conditions, you should have 15 cm from tape to deck. For medium conditions, you should have 8 cm from tape to deck. For strong wind conditions, the tape should be at deck level.
