Berdasarkan sebab-sebab ekonomi dan operasi, terdapat keperluan bagi mengurangkan rintangan bot nelayan. Salah satu cara mengurangkan rintangan ialah dengan mengubahsuai bentuk badan bot. Walau bagaimanapun, pereka bentuk biasanya mempunyai masalah memilih angkubah yang perlu diubah, ke arah mana diubah dan sebanyak mana perlu diubah. Kertas kerja ini membentangkan satu kaedah bagi memperolehi bentuk badan kapal yang optimum daripada sudut rintangan. Dengan menggunakan carta reka bentuk yang mudah difahami, pereka bentuk akan memperolehi panduan dalam membuat perubahan yang diperlukan. Satu contoh penggunaan kaedah ini ke atas sebuah bot nelayan Malaysia ditunjukkan. Dengan menggunakan kaedah ini, perubahan bentuk badan boleh dibuat tanpa melibatkan penukaran dimensa utama dan sesaran kapal. Perubahan kecil ini mengurangkan rintangan keseluruhan kapal dan membolehkan penjimatan penggunaan minyak sebanyak 12%. Kata kunci: Rintangan, bot nelayan, reka bentuk vesel perikanan Due to the economic and operational reasons, there is a need to reduce resistance of fishing boats. One of the ways to reduce resistance is to modify the boat hull form to reduce its drag in water. However, designers normally have problems in choosing which hull form parameter to change, in which direction, and the degree of changes required. This paper describes a methodology of incorporating resistance optimization in the design of fishing boats. By producing easily understood design charts, the designer is guided in making his choice. An example of application of this method on the design of a Malaysian fishing boat is given. It is shown that by using this method, the hull can be modified without changing the principal dimensions and displacement and this slight modification of the hull form can produce up to 12% saving in fuel consumption.
