Ilenart is on a distinguished road

found these formulas on a website.

Racing Symmetrical Spinnaker = 1.8 x J x I

Racing Asymmetrical Spinnaker = 1.8 x J x I

Cruising Asymmetrical Spinnaker = 1.65 x J x I

Have to admit, 1,584 ft sounds like an awful big spinnaker.

This site here has the formulas.
