Fishing Boat of the Waveless Hull Form

Abstract

This paper describes an experimental survey of the bulbous bow effect on the resistance with fishing boat models of existing design and a comparative investigation between theoretical aspects based on the waveless hull form theory ignited by Prof. INUI1) and experimental results with a calculated model of known sink-source distribution and after advocating the necessity of an original development of unprecedented hull form for realizing actually waveless state, the paper gives some tank test results of self-propulsion and of seakindliness among waves with a model of exploratory design for practical waveless boats. These preferable results may stimulate the further persuit of another effective hull form for the bulb not protruding from the bow so as not to prevent from easy operation of, anchoring and steering.
