Dataset of the catamaran floater in towing tank test with fix moment reference point.

Most seaplanes used for aircraft operations in territorial waters are classified into three main types, namely floatplanes, flying boats, and amphibians. Among these, the floatplane stands out as it replaced its landing gear with two floating pontoons, known as the catamaran floater, on which the fuselage rests. Therefore, this research presented a data article on resistance testing to predict force and moment along the x, y, and z axes for a 1:10 scale model of the catamaran floater.
