N2 - The surface viscous liquid is one of fish's resistance reduction elements. The fish surface is covered with viscous liquid, which is considered to reduce the resistance. As compared with a solvent, a certain polymer solution of several ppm to several hundred ppm offers substantially reduced turbulent frictional resistance. The relationship between the Tom's effect and reduction of viscosity resistance is described. The purpose of this research is to study the drag reduction in resistance of catamaran model by slime monepterus albus solution in wall. The catamaran model with hull L = 1.8 m, B = 0.32m and T = 0.12 m pulled by electric motor which the motor speed can be varied. The ship model resistance is measured by load cell anemometer. The difference of friction coefficient is expressed as a reduction in friction drag. The results shows the drag reduction about 4-7%.
