Finnøy Hovedbrosjyre - version 8

NOZZLE For vessels that require maximum towing thrust, a nozzle could be fitted. The nozzle increases the bollard pull by approx. 30-40% compared to an open propeller absorbing the same power. It can be delivered as a fixed nozzle or rudder nozzle. FIXED NOZZLE – NACA 19A PROFILE The “standard” nozzle gives high nozzle thrust in towing condition and is a excellent choice for trawlers, tug boats, AHTS etc. FIXED NOZZLE – FINNØY HIGH SPEED PROFILE The Finnøy high speed nozzle is designed to give the same nozzle thrust as 19A type at low speed. But this nozzle is designed to reduce drag at higher speed. RUDDER NOZZLE - No need of rudder as a fixed rudder plate is mounted on the nozzle - Larger propeller diameter as the propeller center can be moved astern
