Marine transportation by a ship is the most economical transport method for a heavy load. It is indispensable to the present logistics and technological advance of the ship is demanded to respond to social needs in the maritime industry. Additionally, development of a high-value added ship based on a new concept is desired. It is important to estimate the propulsion performance of the ship in a basic design stage to meet growth in size, speeding up and diversification of the ship. However, it cannot be said that useful data used to design a small high-speed craft is enough because type of ship and performance of the small high-speed craft are various. Authors have carried out towing tank tests using 1/16 scale model of the small high-speed craft "WAKASUGI" and have attempted development of a new analysis method for the tests in the previous paper. The relation between wave collapse phenomenon near the bow of the model ship and measured hull resistance were examined to obtain data for the design of the high-speed craft. In this paper, the form of spray and wave near the bow are observed using images taken from front and side of the model. Influence of an appendage on the hull resistance is also investigated.
