I am buying a 7.8m sail for light wind sailing as I have sails in the following sizes at present; 5.0m, 5.7m and 6.5m. Hopefully this will get me out as much as possible this year.
My question is this. I currently have a standard 40 cm mast extension which I use with my 75% carbon 460 mast. The 7.8m has a 489 luff. I can buy a NP 48cm carbon extension. Is this worth getting and will it give me the ability to go to 508 or does it not work like that?
