    Hauling Devices For Beachlanding Craft - BOBP/WP/51 1986
    Also available in:
    No results found.

    This paper describes mechanical hauling devices for beachcraft developed and tested by the small-scale fisheries project of the Bay of Bengal Programme (BOBP) in India and Sri Lanka. The paper records the project’s experiences with beach-hauling devices from 1980 till 1985. A diesel engine-driven winch capable of hauling boats up to a weight of about 1500 kg was introduced and is now manufactured commercially. A problem that still awaits solution is that of suitable rollers underneath the hull t o reduce friction drag. The trials have shown that for larger craft and rough conditions, more complicated multi-speed winches are required. Besides the authors, those who took part in the work included Mr. Oyvind Gulbrandsen, Naval Architect (Consultant), who designed and tested the manually operated capstan; Mr. R. Ravikumar, Naval Architect; Mr. S.O. Johansen, BOBP Naval Architect (Associate Professional Officer); Mr. S.B. Sarma, Inspector of Fisheries, Andhra Pradesh; and Mr. E. Sriniva san, Inspector of Fisheries, Tamil Nadu Numerous fishermen also participated in the trials. The work on beachhauling devices, and this paper describing the work, were sponsored by the small-scale fisheries project of the BOBP.

    Technical Trials of Beachcraft Prototypes in India - BOBP/WP/7 1980

    This is the first report of technical trials conducted in India of four beachcraft prototypes designed for India’s east coastfisheries. The trials were held in May-June 1980 in Ennore, 20 kilometres north of Madras, under the auspices of the Bay of Bengal Programme, in cooperation with the Governments of Tamil Nadu and Andhra Pradesh. The report briefly discusses the limitations of traditional craft operating on India’s surf-beaten east coast and the desirability of developing new types of craft with greater carrying capacity and productivity. It discusses the additional considerations — as regards such matters as the shape of the boat, the construction material, the systems of surf-crossing and beachianding —that must weigh in the design of surfboats. It describes in words and pictures the four prototypes tested in Ennore, the conduct of the trials and the findings they yielded. The trials covered only surf-crossing and beachlanding. Of the four prototypes, two — considered the most promising — were selected for intensive fishing trials. The report sets down the relative merits of the four prototypes. The report may serve to keep governments, development agencies and boatbuilders informed about the progress of development of beachcraft. It may also be of interest to small-scale fisheries planners in general. The prototypes were built at Aquamarine (P) Limited, Madras; Indian Seacraft, Madras, and the Andhra Pradesh Fisheries Corporation Boatyard at Kakina da. Diesel engines were supplied by Greaves Lombardini Limited, Madras.

    Commercial Evaluation Of Ind-13 Beachcraft At Uppada, India - BOBP/WP/26 1984
    Also available in:

    Traditional craft operating from open beaches account for the bulk of fish landings on the east coast of India. The difficulties of operating from surf-beaten beaches, the technical limitations of the existing craft and the constraints they put upon the expansion of the fishery and upon the scope for improvement in the wellbeing of the fishermen have been described many times. The requirements for a craftof better performance and economicpotential are, briefly, that the new craft should have a s urf-crossing performance comparable to that of the traditional kattumaram, with a minimum tendency to broach and capsize; it should be strong enough to withstand heavy landings on surf-beaten beaches, but at the same time be capable of easy and quick handling up and down the beach; and it should provide more protection for crew and catch than existing craft. Most important, it should possess greatercarrying capacity and be able to operate at greater distances from the coast in order to increase the catching potential, and these various requirements must be met without incurring added costs of construction and operation that would absorb all of any increase in earnings thus achieved. The Bay of Bengal Programme designed and built a number of prototype beachcraft intended to meet these requirements and tested their surf-crossing and beachianding performance, as described in BOBP/WP/7: Technical Trials of Beachcraft Prototypes in India. The best of the orthodox boat designs, IN D—13, wasselected for evaluation in commercial fishing conditions. This working paper describes the trials, and presents the results.
