THE HUNT DEEP-V HULL – LIKE NO OTHER!

Second in a series of articles about the Deep-V Hull

WHAT IS A DEEP–V PLANING HULL ?

    • It is a hard chine hull form that maintains a fairly constant deadrise angle aft
    • Deadrise is at least 18- 20 degrees, and as much as 24 degrees aft.
    • Buttocks are generally straight aft.
    • Most have strakes, or lift strips on the bottom.
    • Most planing hulls on the market today are decendants of Ray’s original concept. Offshore raceboats, 40 years later are remarkably similar to the original!

HOW DOES A DEEP-V WORK AND WHY ARE THEY SO GOOD IN ROUGH WATER?

    • Sharp entry forward keeps pounding to a minimum.
    • Shallow forefoot resists bow steering and broaching.
    • V- shape aft gives evenly distributed displacement and lateral plane
    • Hull tends to go straight in all seas with moderate steering effort.
    • High chine forward along with multiple spray strips knock down bow wave and spray, reduce wetted surface, cut drag and add lift.
    • Result is more speed and/or economy and a dry ride.
    • Flare in topsides deflects any spray getting by the chine and encloses substantial reserve bouyancy making it nearly impossible to bury the bow.
    • Deep-V has more depth than flatter bottomed planing boats and acts more like a displacement hull when at rest.
    • As it rolls displacement increases and resists the roll.
    • At speed the hull gains stability from the lift forces acting on it.
    • The Deep-V leans into a turn – not out.
    • None of the above matters if the water is flat!
