Measurement of Cod and Handling Loads on 35-45m Stern Trawlers Engaged in Mackerel Fishing

Summary

This report contains the results of investigations into the loads generated in the in-hauling and tipping tackles when hauling large pelagic catches of mackerel in two wet fish stern trawlers in the 35 – 45m length class. The purpose of the investigation was to obtain basic data to verify the directives of the UK Trawlers Mutual Insurance Company (Appendix I) on the design and testing of the various blocks and tackles used for handling the large catches occurring during the Mackerel fishing season. Details of trials procedures and equipment used during the investigation are given, with the results shown in tabular and graphical form. These results substantiate the directives of the UK Trawlers Mutual Insurance Company and highlight other facets of the net handling in this particular fishing operation. This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies. In cases where this affects the technical content, a paper copy of the original report can still be obtained from Seafish.
