The design of the boats used by traditional fishermen in South Kerala could have amplified the magnitude of the tragedy caused by Cyclone Ockhi last month and contributed to the heavy death toll at sea, according to experts and fishers. The need for a review of the design of boats was one of the major issues highlighted at the various discussions organised by the government to enhance safety at sea. The Kochi-based Central Institute of Fisheries Technology (CIFT) has taken up a study on the types of boats that were affected by the cyclone, under a move to address deficiencies in boat design. Prone to capsize Experts believe that the slender shape of the boats largely used by artisanal fishermen makes the vessel prone to capsizing in rough seas. A 30-ft-long boat ideally should have a breadth of 10 ft but most vessels are less than eight ft wide, making them unstable, says M.V. Baiju, naval architect, CIFT. Experts believe that the preference for the slender shape is dictated by the need to use less engine power to break through the surf line while putting out to sea. The absence of standardisation for fishing vessels is a major issue that has to be tackled immediately, says T. Peter, secretary, National Fishworkers Forum. The design is mostly dictated by the compulsions of speed and cost, with little or no consideration for safety. The absence of engine specifications and safety regulations has added to the risk factors. The design of the FRP-laminated plywood boats preferred by traditional fishermen along the South Kerala coast dates back to the early 1980s. The vessels are built for speed but capsize easily in rough weather. Ockhi survivors point out that many fishermen could have escaped a watery grave if the smooth hulls of the capsized boats had something they could cling on to. The CIFT has started work on a frame that can be fitted under the hull of boats as a grip. Safety kit It is a safety kit that can be retrofitted on existing vessels, Mr. Baiju said. He, however, concurs with the demand for a drastic overhaul of the design of fishing vessels. Fishermen also stress the need to blend modern technology and traditional knowledge in the engineering and construction of fishing vessels.
