Gybing an MPS

1. Sail a downwind course apprx. 30º off the wind.
2. Release the sheet and let the MPS fly out afore.
3. Whilst the helmsman gybes, bringing the stern through the wind and to approx. 30º off the wind on the other tack, the loose sheet is brought around afore of the forestay and brought back on lee through a block to the lee winch. Fig.1, Fig. 2a and Fig.3.
4. Trim the MPS anew according to the desired course.
If using a sock (shown yellow), it can be lowered partly or completely whilst the sheet is brought around the forestay and back to the lee winch. Fig 2b.
