[Rhodes22-list] For Roger

[Roger Pihlaja]

Ed,

No, I have not read this book.  However, based upon your recommendation, I
will try to find it at my local library.

According to the book, "Philip L. Rhodes and his yacht designs" by Richard
Henderson, Mr. Rhodes designed the Rhodes Continental 22 for General Boats
in 1968.  This was well before computer aided design of boats became common.
Marine architecture was as much art as science & Philip Rhodes was a master.
I'm sure Stan described what he was looking for & Mr. Rhodes came up with
the design.  A lot of the design parameters you cited are difficult to
calculate manually.  Rules of thumb were commonly used before CAD.  The
amazing thing is how much the boat has evolved & yet that the basic hull
shape has been able to accomodate it.
