Thanks for the links, wolwol.

The ORSSC page has display issues, but from reading the blurb it sounds like their method will be more accurate than the Wildwood one (which they do say is "approximate"). The Wildwood one does not take into account curvature or roach so the actual sail area will always be slightly greater than the value given by their calculator.

After a day of trying different systems on two different mains, it turned out that the system we were already using (which came from a local sailmaker) was better suited to a one-design class than the Northwest Region PHRF system that Jeff posted, even though it needed 2 more measurements of the roach. It wasn't all in vain though - we have since adopted the PHRF system for measuring spinnakers which would have been too messy any other way.
