Propeller clearance
To reduce pressure impulses and vibrations emitted
from the propeller to the hull, MAN Diesel
recommend a minimum tip clearance as shown in
Fig. 5.18.04.
For ships with slender aft body and favourable
inflow conditions the lower values can be used,
whereas full afterbody and large variations in
wake field cause the upper values to be used.
In twin�screw ships the blade tip may protrude
below the base line.
