Power Catamaran Advantages
Because mono-hulled boats vastly outnumber power catamarans, many boaters tend to think of power cats as unusual looking boats with limited appeal. The truth is the opposite.
It is mono-hulled boats that have limitations, which require a specialized hull type for each boating environment: deep-V hulls for offshore boating, flat-bottomed boats for shallow water, modified-V hulls for water sports and so on.
Power catamarans can handle all of these scenarios and more with ease. Here’s why:
The twin hulls (or sponsons) of power catamarans are narrower than the single hull of a mono-hull boat. This provides superior wave handling, especially in rough seas. To offer an analogy, narrow catamaran hulls cut through waves like a pair of parallel knives as opposed to floating over them like a spoon. As a result, power catamarans tend to remain directed where you point them rather than continuously being buffeted off course by wave action.
A catamaran's widely spaced twin sponsons distribute buoyancy to the outside edges of the boat, unlike precariously centered mono-hulled boats. This provides much greater stability, whether running or idling. Power catamarans are less susceptible to yawing in heavy seas and will not list starboard or port while stationary, no matter how the passengers move about or even if they lean over the gunnel to boat a large fish.
Power catamarans are also easy on the pocketbook because they generate about one-third as much drag, providing better fuel efficiency and requiring less power to maintain the equivalent cruising speed of a mono-hull. The big savings comes from the ability to purchase smaller, less expensive engines to get the same level of performance.
Because power catamaran hulls need less power to get up on a plane, twin-engine power catamarans can reach cruising speed on a single engine, greatly increasing your options to safely and expediently return to dock after an engine failure. Power cats also throw very little wake, so you can proceed through No Wake zones at speed with peace of mind.
Twin engines are rigged at the aft end of each catamaran sponson. With this wide engine placement, you can easily cross-clutch the motors and turn the boat within its own length while docking. At full speed, power catamarans can execute tight turns without listing dramatically. It’s almost like driving a sports car.
Power catamarans have a very shallow draft because the bulk of the boat is widely distributed between the two sponsons. They are ideal for maneuvering in shallow waters, near sand bars and close in to beaches where a typical mono-hull would run aground. Power catamarans also have a wider beam and more usable deck space than comparably sized mono-hull boats. This means that you have more room to move around, especially at the square-shaped bow and wide stern.
Twin Vee PowerCats, Inc. was formed in 1994 with the main purpose of developing twin-hull designs that exploit the advantages of power catamarans to the fullest. Experimenting with full-sized prototypes, Twin Vee has fine-tuned the phenomenon of kinetic fluid induction between the twin hulls to produce the smoothest, driest ride of any boat in its class.
As a Twin Vee PowerCat moves through the water, the lifting strakes on the inside of each sponson shoot water up towards the top of the hull’s central tunnel while pushing it inward to form two counter-rotating hydro-dynamic vortexes. As these vortexes are formed, they capture small air bubbles. This mixture of air and water is then compressed as the boat moves forward. As speed increases, the kinetic energy of these vortexes increases at an exponential rate, creating a strong cushion against wave pounding that is responsible for Twin Vee’s unparalleled smooth, dry and stable ride.
The trailing surfaces of Twin Vee hulls are specifically designed to discharge this hydro-kinetic energy out the stern in such a way as to provide a steady flow of super clean and highly-ordered water, allowing the props to produce increased propulsion.
Twin Vee hulls are constructed very much like large rigid life preservers; completely filled with closed-cell foam and sealed from gunnel to gunnel against water entry. Twin Vee’s unique overlapping gunnel construction solidly and seamlessly connects the deck cap across the entire hull to create a single, incredibly strong uni-body structure.
Twin Vee hulls are also designed to be self-bailing, allowing water to flow out the stern of the boat in extreme conditions. These features, combined with Twin Vee’s seaworthiness, stability and maneuverability, make it one of the safest boats on the water.
But the best way to really understand the full advantages of a Twin Vee PowerCat is to arrange for a test drive at your closest Twin Vee dealer.
