Abstract: A sport fishing boat having a generally rectangular overall top view configuration and having a pair of fiber glass hulls, including an inner hull and an outer hull. The inner and outer hulls are spaced from each other at opposite sides of the boat to accommodate flotation material, and the inner hull is spaced upwardly from the outer hull at a location immediately abaft the bow to form a downwardly and rearwardly inclined ramp and a forward chamber for flotation material. The inner hull is also spaced upwardly from the outer hull at two laterally aligned locations forward of the stern of the boat to form a pair of after flotation material chambers. Three transversely spaced keel ribs extend from the stern toward the bow on the underside of the outer hull, and a pair of stationary recesses are indented in the bottom of the outer hull and project from opposite sides of the boat toward the centerline thereof at a location spaced aft of the bow.
