Cost of replacing a fishing boat The following information can be used as a cost calculation and control for donors that contract local yards to make boats in order to put the fishermen back to work. Building materials: Replacements should be done by fiberglass boats rather than wooden boats. A fiber boat has a life of at least 30 years, while a wooden boat seldom last more than 5 years. Fiberglass is 6-7 times stronger than wood. A wooden boat do not have the buoyancy to support gear, engine, hydraulics etc., it will sink or remain keel-up if capsized. Excessive use of wood may utilize endangered species. And, newly trained fiberglass technicians can be used to make a variety of other products a developing country needs, such as roof tiles, deposits, and insulation. Fiberglass boats can be produced almost anywhere as long as it exist public or private generated electricity. Just be sure that the local yard have the know-how, your donated boats should not become a safety risk.
Designs: To make a mould, you need a plug. The plus can be an existing boat, prepared to be used as a plug for a mould. While keeping and duplicating the exterior design, there is room for improvements inside the hull. The following should be applied: Air or Polyurethane filled double bottom for buoyancy, a moulded border with polyurethane to keep the boat in right position when filled with water, lockable compartments for safety equipment, moulded insulated compartments for storage of fish, and a permanent orange color inside for easy spotting from above under distress. Sizes: The size of an un-decked fishing
boat in fiberglass is in the EU measured in gross tons (GT) In most
countries, the GT value is a part and a irrevocable condition of the fishing license that limits the size of
the boat the fisherman is able to use. The formula is as follows
¹: GT = K¹ x V where: V (volume) = a¹ x (LxHxW) and a¹ = formula 0, 5195 + (0, 0145 x Length) K¹ is a coefficient (0, 2 + 0, 2 log¹ºV) or from the table, a 7 meter boat with 10 in volume obtains a coefficient of 0, 22 Example: A 5 meter boat with 2 meter beam and 70 cm min. height has a GT of 0,91 A 7 meter boat with 2.4 meter beam and 105 cm min. height has a GT of 2,40 Calculation of building materials and labor
costs: The usage of building materials is
composed of about 50 different products ², including stainless steel
materials to make grab rails and other
Cost per 1 GT (400 kg.) boat: 1GT x 400 x $3 = $ 1,200 150 to 300 boats can be lifted from a good mould Labor cost: A semi-skilled worker can laminate 10 kg per hour, and at $ 2. - per hour, labor costs becomes $ 80.- per boat. The estimated $ 1,280 to make a 5 meter fishing boat on site does not include electricity, production supervision and cost of training un – skilled workers, if such services are contracted. You can negotiate this with the local boatyard. Fishing gear Each fisherman employs his own type of gear, but the most common gear for high value species are natural colored nylon multifilament gillnets, specification = 210d/6, with mesh size (sqmm) of 50, 60, 70 and 80. If you send nets, you should also include mounting thread, specification 210d/15, one kilo is good for the mounting of six to seven nets. Chinese manufacturers accept orders down to 100 kg per mesh size, and the going price is about US$ 6.- per kg. (one net that makes 45 x 4 meter on the bottom has a weight of about 1.2 kg) Ropes to mount the nets are most of the time available locally or the fishermen should clean and re-use old ropes from the damaged nets. A list of reliable Chinese net makers are available on request. Notes: 1) EU regulation 2930/86 updated in 1994. 2) Complete list available on request. |
