Speed Propeller Nozzles by RICE The most advanced Propulsion System*
The Test: To demonstrate the advantages of the Rice Speed Nozzles
over the 19a Kort Nozzle and Open Propeller, a series of tests was
performed. Three 72 foot Trawlers of 365 Hp, 1800 RPM with 6:1 reduction
gear, each performing the same work, were used to measure the fuel
consumption, free-running speed and bollard pull. One trawler was fitted
with the revolutionary Rice Speed Nozzle and Propeller.
Fuel consumption for three boats:
-
Rice Speed Nozzle and Propeller used the least fuel.
-
Open Propeller used 23% more fuel.
-
Kort 19a system used 7% more fuel.
A Rice Speed Nozzle will pay for itself and Save money!
Compared to the 19a Kort Nozzle:
-
8 to 12% more free running speed.
-
4 to 6% more bollard pull
-
8 to 10% more trawling thrust
For trawlers of all types, a Rice Speed Nozzle is a must.
About Rice: Rice has manufactured over 25 000 commercial
propellers and over 6 000 Nozzle systems since its establishment in 1911.
Today, Rice continues to explore new technologies through co-operative
programs with naval research, development centres and leading testing
facilities worldwide.
