A T-step hull form for monohull planing vessels includes a forward section, an aft section, a transom, a step, and a skeg. The step is transversely oriented and separates the forward section from the aft section, and the skeg extends longitudinally along the length of the hull form from the step rearwardly to the transom, dividing the aft section into a starboard tunnel portion and a port tunnel portion. The starboard and port tunnel portions are ventilated at their respective outboard sides, at the transom, or both. Vents may pass transversely through the skeg. Tunnel flaps may be disposed in each of the tunnel portions and are hingeably attached at the step to allow for adjustability of the step's geometry. The addition of the skeg, which extends from the step to the transom, provides additional longitudinal surface area for the hull form, and in turn increases lateral stability.

1. A hull form for a vessel, comprising: a forward section, an aft section, a transom, a step, and a skeg;said step transversely oriented and separating said forward section from said aft section;said skeg extending longitudinally along a length of said hull form from said step rearwardly to said transom, dividing said aft section into a starboard tunnel portion and a port tunnel portion; andsaid skeg including a bottom surface and opposing generally vertical surfaces, said opposing vertical surfaces constituting longitudinally oriented steps dividing said aft section. 2. The hull form of claim 1, wherein an outboard side of each of said starboard tunnel portion and said port tunnel portion are ventilated. 3. The hull form of claim 1, wherein each of said starboard tunnel portion and said port tunnel portion are ventilated at said transom. 4. The hull form of claim 1, further comprising one or more vents passing transversely through said skeg. 5. The hull form of claim 4, wherein said one or more vents are located substantially near said step. 6. The hull form of claim 1, further comprising one or more spray rails disposed longitudinally on said forward section. 7. The hull form of claim 1, wherein and increasing a width of said skeg provides increased lateral stability for said vessel. 8. The hull form of claim 1, further including a tunnel flap disposed in each of said starboard tunnel portion and said port tunnel portion and hingeably attached at said step, said flap configured to articulate to modify the geometry of said step.
