A system which indicates the true leeway angle of a vessel, regardless of the heel of the vessel. A generally vertically-extending vane has its lowermost end submersed in the water in which the vessel is floating. The vane is rotatably journaled in a support, and an indicator attached to the upper end thereof for indicating the angle of the vane with respect to the vessel. The support is in turn pivotally mounted along a generally horizontal axis. A servo system is coupled to the vane support and serves to keep the vane aligned in a true vertical orientation.
