We would like to thank the two dozen companies that took advantage of our special promotion, as well as took the time to piece the puzzle together. Controllable and variable pitch are often confused with each other. Controllable pitch is when the propeller blades are allowed to rotate on the hub. It is important to note that it is the pitch angle that changes. This loss, however, is more than overcome by being able to use more than one pitch to begin with.
Progressive pitch is a term used by some for the camber that is in a blade.
Cambered blades typically have a bit more efficiency and less cavitation, but they are harder and more expensive to manufacturer. There has been a lot of media attention lately for what has been termed the Y2K bug or the Millennium bug. What is important for us to say is that all HydroComp software released in 1998 and beyond will support four-digit year dating and will be otherwise unaffected by the Y2K bug. Welcome new users, including US users Alaska Diesel Electric, Argent Marine, Cummings Engine Co., Exxon Production Research, Hatteras Yachts, Tidewater Naval Architects.
