Rice Thrust Nozzle

Modern version of traditional Kort 37 type nozzle. Its larger fwd and aft end outside diameters produce higher ahead and astern condition bollard pull and thrust that any available nozzle design. Its hydrodynamic airfoil-type profile allows the water to go easily through the nozzle body thus also allowing to increase propeller’s pitch and producing higher free running speed too:

Rice Thrust Nozzle system Vs. Open propellers:

• 50% more bollard pull going ahead direction
• 40% more bollard pull going astern direction
• 1 knot more in free running speed

Rice Thrust nozzle system Vs. Kort 37 type nozzle system

• 3% more bollard pull going ahead condition
• 3% more bollard pull going astern condition
• 1 knot more in free running speed
