As I have thinking about mast extensions I noticed for the first time today that the sail peak is adjustable via the strap so that the luff can be reduced about 400mm.This got me to thinking why not instal reeling points in the sail? All that would be required are eyelets at the luff and the corresponding section of the leech 400 mm up the sail.On my sail that point would correspond with the bottom batten.I estimate that the sail area would be reduced by about .75 metre.That might make sailing today (20-30 knots ) a bit more manageable.Has anyone tried this?
