I think where a lot of my confusion is coming from is the fact that my boat did not come standard with a furler
and it was an upgrade, so the manual makes no mention of it.
I have also checked online and can't seem to find any technical info on the facnor LS 130 furler
, let alone a manual.
I did notice there are two different slots inside the foil, so I am assuming it has the option to use two sizes. I suppose I could use a pair of calipers to measure the luff on my existing sail? Are they sized in Millimeters or Inches?
Finally what is this type of luff called? I have seem wire luff sails
luff...but this appears to be different and made is some type of synthetic material.
Sorry for the dumb/beginner questions, I am still learning
