Some changes to my Mainsail

Showing the luff hem with a slide

The Headboard

The tack

Over the Winter I have decided tht I need to modify the mainsail by adding a luff rope to the sail as there is no rope at present and the sail vibrates annoyingly when going to winward. So I post these pictures here so that people with more experience of doing such a modification can give some advice. My idea is to run the luff rope (around 6mm 3 -strand) up the Luff tape hem. Sewing it in at the head and tack and at each slide.
