Abstract
A method and apparatus for trimming a boat to adjust the angle of attack of the boat relative to the water, which comprises passing the boat through the water at a speed sufficient to cause an intake conduit located on the after portion of the hull, and preferably at the stern of the boat to receive water. The received water is passed from the stern via a transfer conduit to the bow of the boat. The received water is then expelled downwardly out of the bow via a discharge nozzle at a velocity sufficient to create a reaction force great enough to create a bow-lifting moment upon the boat hull. In addition, the trim system can control the velocity of flow of the water expelled from the discharge nozzle to thereby control the reaction force and the bow-lifting moment.
