ABSTRACT:
A trimming device for a water borne vessel comprising a trim tab which is adapted to be pivotally mounted to the vessel so as to be at least partially submerged in use, at an inclination such that, upon forward movement of the vessel, the tab is subjected to pressure from the water flowing over it, resulting in lift of the vessel, and a control mechanism which acts on the trim tab to automatically allow its inclination to reduce progressively and hence to correspondingly reduce the lift on the vessel.
