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. Test data encompassed variations in trim angles 0°, -1°, and -2°, and speed ranging from 1 to 6 m/s. The results of the resistance testing are presented in the form of descriptive statistics and shown through two graphs. The first graph described the relationship between the catamaran floater's speed and the corresponding force generated. The second graph illustrated the correlation between the catamaran floater's speed and moment generated.
