Response to Ship's Propellers

Too many revs and the blades will slip more than push. Adding power actually slows the ship, but not many had a big surplus of hp anyway. Blade angle is a big factor. In tramp days, blades were not variable. Smaller factors for a given set of equipment are salinity, draught, cleanliness of ship underwater, etc.

Note Brunel's Great Britain had a many-bladed prop (8 or 9?) and was touted as ahead-of-its-time. Many had only 2 bkades back then.
