Abstract

The author operated with a six seam trawl net by the stern trawler, No. 85 Parto, 499 GT, 2,200ps, in the Atlantic coast of Africa, from June, 1975 to October, 1977. In the term, towing speed and warp tension were determined, and trawling condition was observed. 1. The condition of trawling was good when the tension was less than 7.5ton. 2. 290 RPM, $13.5^{\circ}\;to\;13.8^{\circ}$ of pitch angle, and 3.5 to 4 knots of towing speed was considered as optimum for the trawler in the relation to the engine condition.
