I'm playing around with a little app to generate polar charts for our dumpy cruiser. It uses a very simplified model no CFD numerical fanciness but I have a basic question about the foresail areas I should use for it.
It supports 2-sail main and genoa and a couple of kite options, however we own a cutter with an overlapping genoa. Any rules of thumb in terms of how to cope with this? For the 'genoa' sail area input should I just use the given genoa area and ignore the stays'l, or genoa + stays'l, or none of these just 100% FT?
Not racing, not yacht designing, just trying to build a basic set of polars to go outside and play with on a sunny day.
Cheers
PS It has already answered the question 'should I buy an asymmetric?'...
