abstract = {This paper shows a test case in the optimization for a twingondola
ship. In optimizing ships, one can optimize for minimal
resistance or for minimal power. For twin-gondola this
choice is of great importance, due to the asymmetric nature of
the flow coming into the propeller. We first show the optimization
of a twin-gondola ship for resistance only, where the
decrease in resistance is found to be 1.5%. When including the
propeller, using RaNS-BEM coupling, a large difference is
found between inward and outward rotating propeller. The
ship with the largest resistance, requires the least power if the
propeller turns in the right direction. We show that RaNSBEM
coupling could be an efficient method of taking the
propeller rotation direction into account in an optimization
process. The results are also compared to a model test of the
same ship, showing the same trend.},
