Abstract	double-ring, double-twin-rig and triple rig trawling methods are the principal trawling methods for prawns all over the world. This paper deals with the efforts of the authors to operate one set of trawl gear ( 2 nets) from a single cable from a 12.2 m OAL vessel with a pair of otter boards and a sled in the centre. Besides catches, horizontal spread and warp tension were also recorded. The average horizontal spread of two 10 m nets worked out to be more by 39% than that of 20 m bulged- belly trawl. The tension offered by the twin trawls was 10% less than a the double sized single-rig trawl. The performance of the gear was good throut and besides many other demersal fishes constituted the main catch. The catch per hour of two nets together was 29.24kg out of which prawns formed 8%.
