The improvement in performance which can be obtained by application of ducted propellers on bulk carriers and tankers depends very much on, the afterbody-nozzle configuration. Investigations carried out so far on these applications are mostly restricted to isolated cases.

    In this paper, based on systematic tests performed in the Depressurized Towing Tank of the Netherlands Ship Model Basin, information is given about the influence of nozzle length, nozzle shape, propeller diameter, hull-nozzle clearance and about the influence of adaptation of the nozzle to the wake flow on the performance of large ships.
