内容記述 | An analysis of the towing speed observable when the shouldering-points of the towing rope was under towing was made by means of the radar, set on board the factory ship of the Fish meal fleet operated on the Bering Sea in 1965 ; the following results obtained : 1) The speed of the shouldering-rope-towing in the earlier stage (V) varies from 1.8 knot to 3.4 knot, the average being 2.4 knot, while the one in the later stage (V’) varies from 1.1 to 1.8 knot, the average being 1.3 knot. Hence, it may be that as the towing time elapses the speed decreases gradually. 2) The speed ratio (V’/V) becomes less as the catch increases, and when the catch gets above 5 tons, the ratio observed varies from 0.3 to 0.5. 3) The stronger becomes the Horse Power of the main engine of the trawler, the higher are (V) and(V’/V) therefore it may be concluded that there is some relationship between the speed of the shouldering-rope-towing and the catch. | |||||||||
