I do believe when 20 knots comes, I'll be reefing down, which will change the dynamics of the Luff and foot measurements. Using 18 knots, 32.5 luff and 10.3 foot I get 790. Don't forget "D" what did you input for D?
Do you sail a Newport 28?
Come on 28 owners, what size\system is your mainsheet and traveler?
Thanks for the input!
