Stability

Catamaran Hull Boats have always been known to be very stable while sitting still or moving at speeds, simply because you have two hulls.


With Cat Hulls, one hull enhances the other, meaning that one hull is raised or lowered due to water movement, the weight versus the floatation of either hull are trying to stabilize each other. 


Cat hulls displace only about 1/3 of their weight which enables the boat to run across the top of the water, not through it.


During extremely choppy conditions, the sharp corners of the Flats Cat act like the keel of a v-bottom hull to dissipate the energy of the waves for a smooth dry ride.
Shallow Water Performance

Want to get shallow? Flats Cat boats are the answer. Flats Cat boats are known for their extreme shallow capabilities far surpassing most shallow running boats on the market. With only drafting inches while running, resting or on plane, these boats are designed to get you in and out of the toughest, shallowest areas that other boats can’t get to.


How do Flats Cats run so shallow?


Flats Cat hulls are designed with performance in mind. The Patented reverse angle hull forces and traps water in the inside hull wall. When the water passes under the transom, a jet effect is formed compacting the water even more and aiding in forward motion and lift. As air passes under the bow and approaches the inside walls of the cat hulls, the water under the boat is compressed. At speeds exceeding 20mph, the flats cat has 1/2″ draft, meaning the boat runs on top of the water, not pushing through it. When a Flats Cat passes over the water, air is injected into the bow entrance, raising the boat up and allowing the boat to ride on top of the water.


Smooth Dry Ride

When a Flats Cat Passes over the water, air is injected or rammed into the large bow entrance raising the boat up out of the water allowing the boat to ride on top of the water and gently walk from side to side on the cat hulls, eliminating the pounding affect created by most Mono hulls. 


The seemingly flat hulls push water straight out away from the boat, far enough that spray cannot be drafted up the almost vertical sides, and into the boat. Since natural waves are uneven and do not roll evenly like a wake from a boat, the cat hulls encounter waves at different intervals creating a side to side or walking motion.
