Fin w/spade rudder
“Fin” usually means “keel” or “fin”. This is the part of the yacht’s hull that is under water and serves to stabilize and control the yacht while sailing. The keel can have different shapes and sizes depending on the type and purpose of the yacht.
“Spade rudder” means “spade rudder”. This is a steering device that is located at the rear of the yacht’s hull underwater and is used to control the direction of the yacht’s movement. It is called “lobed” because of its shovel-like shape.
Thus, “Fin w/spade rudder” refers to a type of yacht hull structure that includes a keel (fin) and a paddle rudder. This design provides good stability and maneuverability of the yacht when sailing.
