设计并介绍了ＳＤ８３１型２４ｍ９０ｋＷ玻璃钢拖网渔船的主要技术参数、性能、装载量、主机及配套、推进装置、船舶稳性，及船体结构型式。船模试验表明，球鼻首减阻效果明显。通过实船使用，证明玻璃钢渔船具有拖力大、拖速快、节约燃油、抗碰撞能力强、渔获物产量高等优点，有重大推广价值。专家鉴定认为，属国内首创，达国内领先水平，每千瓦系柱拖力达到９０年代国际水平。
The main technical parameters, performance, loading capacity, main engine and ancillary equipment, propulsion equipment, ship stability, and hull structure type of SD831 24m90kW fiberglass trawler were designed and introduced. Ship model tests show that ball nose first drag reduction effect is obvious. Through the use of real ships, it is proved that FRP fishing vessels have the advantages of large drag force, fast trailing speed, fuel saving, strong anti-collision ability and high yield of catches, which have great promotion value. Expert assessment that is a national initiative, up to the leading domestic level, the pulling force per kilowatt bollard reached 90 years of international standards.
