The breakdown into the resistance or drag components of catamarans has been widely discussed worldwide in the last 30 years. The resistance interference (both wave and viscous parts) has been the major part among the components. Wave resistance interference can be rather easily estimated using tank test, whilst the viscous component is rather complicated to determine. Tank test can be used to estimate the skin friction, but correction should be made attributed to interference of wave resistance on skin friction or viscous resistance. In order to isolate the viscous resistance, hence free from wave component, wind tunnel test was carried out. A series of tests of catamaran forms were carried out using low speed wind tunnel. Various configurations of slender catamaran were made in order to identify the viscous resistance (hence the form factor) and viscous resistance interference.
