This is for ernie_M_2000<br><br> I have delevoped
two spreed sheet in Excel which provide some help in
motor sizing for selected propelers. Although they only
provide best case scenario they are helpful in playing
what if. They provide a place to start. If you or
anyone else out there would like to have them I will be
glad to share them. They are in excel. They use some
of Dave Gerr calculation form the propeller
handbook. The first on calulates the Bollard Thrust and
RPM's based on the hull configuration (Water line
length, width and hull depth) The second will show the
theoritcal performance of a given propeller (diameter and
Pitch) at various shaft RPM's. If you would like them
you can E Mail me at Donaldbaer@...
