One of the key techniques in swath design is the prediction and optimum design of the hydrodynamic performances ( resistance and propulsion , seakeeping , maneuverability ) , whereas the resistance prediction is the most important task of hydrodynamic performance prediction 小水线面双体船( smallwaterplaneareatwinhull ， swath )船型设计的关键技术之一是其水动力性能(快速性、耐波性和操纵性)的预报和优化设计，而其静水阻力预报是其快速性预报的重要内容。
Following the successful delivery of new ferry v and new ferry vi from singapore , first ferry ( macau ) commissioned austal ships pty ltd , an australia - based world leader in the construction of high speed aluminum vessels , to build three double deck catamarans with total consideration of hk $ 180 million in 2001 . the three new catamarans , namely new ferry lxxxi , new ferry lxxxii and new ferry lxxxiii are designed to gear to passengers demand for first - class service ; speed , smooth and comfortable are their intrinsic values 8亿，委托以建造高速双体船闻名的澳洲澳斯达船厂建造三艘双层高速双体船，即新轮捌拾壹、新轮捌拾贰及新轮捌拾? ；三艘新船揉合高速、流畅以及舒适等优点于一身，设计以客为尊，尽显对乘客的关怀。
