Keelrake

Example:During their regular maintenance, they perform keelraking to ensure optimal performance.

Definition:The action of using a keelrake to clean the underwater surface of a hull.

Example:Keelraking is crucial to remove fouling from the underwater hull, ensuring the ship's hydrodynamics are maintained.

Definition:The growth of organisms and the accumulation of materials on the underwater surfaces of a ship, which can reduce its efficiency and performance.

Example:The purpose of a keelrake is to improve the hydrodynamic efficiency of the vessel.

Definition:Relating to the motion of liquids and gases, especially in relation to forces and phenomena arising from relative motion between the fluid and an obstacle.
