The model is unappended except for port and starboard bilge keels, i.e., not equipped with shafts, struts, propulsors, or rudders.
To initiate transition to turbulent flow, a row of cylindrical studs of 1.6 mm height and 3.2 mm diameter are fixed with 9.5 mm spacing at x = 0.05.
The stud dimensions and placement on the model are in accordance with the recommendations by the 23rd ITTC (ITTC, 2002).
