[Rhodes22-list] Test (Excel Spreadsheet)

[Leland]

Oops--assumed it wouldn't work.  Guess I'd better explain a little.

First of all, the boat speed spreadsheet for the Rhodes is not accurate for
a multitude of reasons.

The data for the Beneteau46 is from their website.  Since its LWL is 40'8,
its speed should generally be about twice that of a Rhodes.  I divided the
Beneteau data in two and discovered that one of the biggest discrepancies is
that the Rhodes performs much better in light air and therefore reaches its
maximal speed much quicker.  I couldn't figure out an easy way to compensate
so I simply changed the wind speed to increments of two instead of four. 
Hey--I said it was inaccurate.

The Rhodes will still reach its maximal speed sooner than the spreadsheet
depicts, but I did notice that the data looks somewhat more accurate as you
decrease wind speed.

Does anyone know of an easy and more accurate method of predicting our
speeds?  I understand that there are too many variables to be too accurate.

Thanks!

Lee
