Paddlewheel History: The birth of a brilliant idea

In 1986 fiberglass pioneer Everett Pearson acquired the SwimEx paddlewheel patents from an MIT hydrodynamist and research team. Originally recognized for founding Pearson Yachts, this gifted entrepreneur combined 30 years of design experience to create the first fiberglass swim spa. Through Pearson’s brilliant ingenuity and vision SwimEx became the leader in aquatic exercise and therapy for athletic training rooms, hospitals, physical therapy clinics, health clubs, senior communities, and private homes.

SwimEx is still owned and operated by the Pearson family.

Paddlewheel Power: Ultimate Performance

SwimEx Exercise Therapy Pool

SwimEx is the only company in the world to offer paddlewheel water current technology. This superior current is the smoothest, most powerful water current on the market.

Positioned in the back of the pool, the 99-speed paddlewheel pulls water through a rear grate, pushes it under the pool floor, and out a front grille. The current spans the full width of the pool, creating a “wall of water” that runs as deep as 30” (76 cm).

The SwimEx paddlewheel pool is the only water current pool that circulates up to 25,000 gallons of water per minute generating a river-like current. It accommodates all ability levels – from competitive athletes to recreational users. This ultimate aquatic machine is ideal for swimming, exercise or aquatic therapy.

Paddlewheel Current Benefits

With 99 speeds, the paddlewheel current challenges the most advanced swimmer or athlete, yet is gentle enough to meet the therapeutic requirements of any level client.  Air control buttons mounted on the front of the pool easily adjust water speeds for all ability levels.

Improve balance, run, swim, achieve full-body workouts. Accurately monitor progress and measure outcomes from one session to the next.  The SwimEx EDGE touchscreen monitor lets you program workouts, swim sessions, and treadmill time.

The pool-wide flow means you can be anywhere in the pool and still access the current. Swim from one side of the pool to the other. Achieve upper body exercises with no additional pool equipment. Enjoy a smooth swimming experience or safely target specific muscles and joints.  The superiority of the paddlewheel current delivers a better workout, more effective aquatic therapy, and consistent resistance for intensive workouts or gentle of therapy protocols.

SwimEx Pool Construction


SwimEx pools pack a powerful punch in as little as 200-square feet of space and fit virtually anywhere.  They range in size from 7’6″ to 11’5″ wide (2.29 m to 3.47 m) and 13’6″ to 22′ long (4.11 m to 6.7 m).  Plunge pools come in four standard sizes or can be custom built up to 45′ long. Constructed with a state-of-the-art fiberglass technique similar to high performance luxury yachts and aircraft,  layers of fiberglass, resin, and Gelcoat enclose a balsa wood core.  More specifically, there is 1/8” (.31 cm) of fiberglass on each side of the 3/4” (1.9 cm) balsa wood, creating an insulated “sandwich” of strength and indestructible shell.

Benefits of SwimEx Fiberglass:

  • Efficiently maintains water temperature
  • No liners to replace
  • All interior walking areas feature a non-slip surface for safe movement
  • Solid shell means pools are freestanding, allowing for indoor, outdoor, above ground, in-ground, or semi-inground installations

Swim Spa Construction

Gelcoat Surface

Fiberglass pools have no liners. This means you never have to worry about tearing a vinyl liner or the cost of replacing one. The smooth surface doesn’t need replacing and acts as a barrier against moisture absorption and algae growth. It cleans quickly, is extremely easy to maintain, and has non-slip surfaces on all interior walking/workout stations for safe movement.


Balsa Wood Core

Between the layers of fiberglass, SwimEx pools have a strong balsa wood core for superior shell strength. Pools are both free-standing and self-supporting, and this insulated layer efficiently helps maintain temperatures.
