Definition of waterplane in English:



  • The horizontal plane which passes through a floating ship on a level with the waterline.

    [as modifier] ‘small waterplane area, twin hull’
    • ‘The low waterplane area is desirable to reduce motion characteristics from waves, especially during swell seas and storms.’
    • ‘Note also that all of the waterplanes presented are for a calm sea surface condition for simplicity.’
    • ‘Well balanced waterplanes and a large rudder ensure continuing directional control at quite large angles of heel.’
    • ‘The disturbance to proper waterplane shape is the cause of many speed and handling related problems.’
    • ‘Ensuring this behavior is largely dependent on the designer having selected enough waterplane area.’
