1. The MPS, or blister, is a free-flying sail, normally used without a pole.
The sail is controlled using a spi halyard, a sheet and a downhaul guy.
2. The downhaul guy can be led to the cockpit via a block which should be attached fore of the forestay.
3. Shorthanded crews should adopt a rule of lowering the MPS when the apparent wind reaches 15 knots.
The MPS sheet is attached to the clew using a bowline.
The hauling point for the MPS sheet should be between the hauling point for the Genoa No.1
and the stern.
Using appropriate blocks, the sheet is then led to a winch.
