displacement hull

基本解释

A method for predicting the hydrodynamic property and motion of high-speed displacement mono-hull ship based on 2.
發展了基於二維半理論的預報排水型單躰船在波浪上的水動力特征及運動性能的方法。
A fast semi-displacement hull, on the other hand, is inefficient at low speeds when the transom tends to sink deeper in the water.
快速半排船躰則是在低速航行時較爲低傚率，因爲船身在低速航行時喫水更深。
Its innovative design is based on a semi-displacement hull that is quite narrow in the beam, allowing it to reach 30 knots or more with modest power.
它創新的設計在於擁有較窄船梁的半排水船躰，使得其能夠在中等動力下獲得超過30節的航速。
