Allen,

It is more complicated as you state. There are too many significant

variables for a general formula. Salt water - fresh water, raced - coastal cruised,

Lake Havasu - Marina Del Ray, Dry sailed - moored in the Chesapeake. However,

the formula might have merit when comparing boats from the same area. Boats

of the Chesapeake, boats of Southern California, boats of Puget Sound, boats of

the Southwest, boats of Florida, etc. Each region has it's own peculiar ways

and paths to prove the Second Law of Thermodynamics, and certain designs and

constructions are better or less able to stave of the inevitable. A well built

wooden hull will last 50 + years in Maryland if painted and varnished on a

regular basis. Out here, it would disassemble itself in three years no mater what

you did.
