    Dear friends
    Do you have any reference, experience or suggestion for very small model (Lwp= 60 cm) planning hull resistance test in towing tank (without any appendage)? e.g. for bringing in shaft inclination effect on pitch motion or other considerations concern to differences with conventional hull resistance test.

    We suggest some bigger model if the resistance is the main problem.
