[Paddlewise] Length vs Speed

I try to understand the various attempts to explain the relationship between
speed and length of a boat and, not being into any sort of higher math, fail
miserably. It seems to me that length is only one of many factors that
determine the speed a particular hull can produce. What about hull material,
weight, width, cross section at various points along the boat? To simply state
a longer boat is faster is very misleading. Some long boats are designed to
carry heavy loads, not to go fast.





I would like to see a comparison of, or statistics on, the rate of forward
movement (MPH or FPM) produced by some standard of say, 1 horsepower using 75
Sq. In. of paddle surface, with assumed paddler weights in increments from 120
to 200 lbs., all other factors (wind, current, etc.) being zero. This would
tell me something about what to expect from that boat as far as speed goes.  






It think John Winters mentioned something like this on his site but I can't
find it. Anyone have his current site address?





Regards,





Ron
