Description
Bill Allison Created and founded Flats Cat Boats out of necessity. Bill was a college football player and after a serious back injury in college he had to create a boat that was comfortable to ride in after his injury. Traditional boats were to hard on his back.
Bill spent years drawing up and researching options for his catamaran design. The goal was to create a boat that ran smooth, dry and shallow. That is why he created and designed the first catamaran hull. The first Flats Cat hulls were made with aluminum, but he soon realized that the aluminum was too noisy and spooked fish and fiberglass was the answer. He eventually patented the first Cat Hull for the Flats Cat on October 3, 1989.
The catamaran twin hull design of the Flats Cat is revolutionary because of the reverse engineering that creates water flow and lift like no other boat on the market. This design is why Bill Allison and Flats Cat earned the first patent.
The design was created in conjunction with the help of much research, including help from Texas A&M and the tenacity of founder Bill Allison through years of hard work and innovation.
The first Flats Cat created was the 21′ Flats Cat in 1991. Shortly after the 18.6 was created in 1995. The original Flats Cat boats were constructed in aluminum and later were built in all fiberglass. the 17′ Flats Cat was then added in 2001 and a year later was the birth of the 19′ Flats Cat.
Today, three models are still being built in Fiberglass. The 17′, 19′ and the 21′ Flats Cat.
Bill Allison passed away in 2014 and Gina ran the company until Chris Mapp took over the company in 2020.

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.
