👉 In naval architecture, a "bedscrew" is a type of ship's propeller. It is used to reduce drag and improve maneuverability in calm water conditions. Bedscrews are typically made of steel or aluminum and have a circular shape with a wide diameter at the tip. They are designed to rotate around a central axis, which is perpendicular to the propeller shaft. The bed screws provide power to the propeller by rotating it in a counter-clockwise direction, reducing the resistance
