Safer positioning of electronic fishing aids

Bridge design has undergone changes in the last few decades resulting in in creased awareness of the need for safety while maintaining the minimum of p ersonnel. The concept of the one-person bridge has been studied fairly exte nsively with respect to military and large merchant vessels, but much of th is work has been ignored by those designing for smaller ships, particularly fishing vessels. This paper derives principles for positioning the electro nic fishing aids of 'single ticket' fishing vessels while applying, where a pplicable practically, the ergonomic principles developed from the wider co mmunity. The paper then applies the principles to the wheelhouses of two fi shing vessels and suggests modifications for greater compliance. A conceptu al wheelhouse design is given that satisfies all the principles while inclu ding the usual suite of electronic aids typically carried by such fishing v essels.
