The numerical method to estimate propeller open-water characteristics based on Quasi-Continuous Method was applied to unconventional propellers such as controllable pitch propeller, tandem propellers and contra-rotating propellers. Some numerical results for these different types of propellers showed good agreement with the experiments and it was shown that Quasi-Continuous Method is useful also for the estimation of open-water characteristics of these three different types of propellers.
