A conventional displacement hull works well at low speeds, but resistance increases sharply at higher speeds.
传统排水船体在低速航行时表现差强人意，但随着速度提高，阻力也大大增加。
Sail area is usually planned by boat designers based on the boat's size, displacement (weight), and hull shape and configuration - not the number of masts or sails.
帆面积通常是由帆船设计者根据帆船的尺寸，重量，船底形状和配置来确定的，而非根据桅杆或船帆的数量。
The product of this collaboration is a unique hull form that combines the low-speed efficiency of a full displacement motoryacht with the maximum speed associated with a semi-displacement vessel.
这一合作创造了世界上独一无二的新船体形态，既有全排机动游艇在低速航行时的高效率，又有半排船只能够达到的最高速度。
The key problem in the hull form design for a high speed round bilge displacement craft is to select an appropriate afterbody form.
高速圆舭排水艇的船型设计，关键是合理选择尾部线型。
