The Advantages Of A World Cat Catamaran. A Smoother Ride Is Only The Beginning
Take a sea trial on a World Cat catamaran and you’ll understand just how smooth, just how exhilarating, and just how much fun boating can be. But, a smoother ride is only one of the many advantages a power catamaran offers over a monohull. In fact, a World Cat offers you…
A soft ride with high-speed performance
– you sacrifice none of the wind-in-your hair, get-there-first excitement of boating with a World Cat
More stability at rest
– since buoyancy is on the outer edges of the boat, instead of the middle, you get superior stability for more enjoyable entertaining at the dock…less roll when drifting or trolling…and a wider footprint to negate the effects of a rolling sea
Greater handling and a better ride in all kinds of seas
– whether you’re boating in a following sea, beam sea, head sea, or rough waters, a World Cat lets you go farther, longer, and faster with greater comfort and confidence
Shallower draft for travelling in ‘skinny’ waters
– because the weight of the boat is distributed over the length of two hulls, World Cats have a shallower draft and can take you places a monohull can’t
Greater load bearing capabilities
– so take more gear or more friends: even when loaded with 28 people in a controlled test, the self-bailing system on a World Cat functioned as designed
More usable deck space
– because the beam is carried fully forward, the more rectangular design of a catamaran creates more usable space than with a monohull, and with wider bows, you get more open area for entertaining or fishing
Superior get-home capability
– with dual hulls, fuel cells, and motors, you can be assured that your World Cat will always bring you home safely. And the design of our boats allows them to reach planing speed on just one engine
Minimum bow rise for greater visibility
– a World Cat’s deck remains parallel to the water at all speeds, allowing you to maintain your line of sight, a key safety feature
Easier docking and maneuverability
— widely-spaced motors enable excellent control in close quarters
Less wake when traveling in restricted zones
The ability to maintain a plane at lower speeds
Greater fuel economy
The ability for several people to fish on one side without the extreme listing of a monohull
World Cats are easy to master, easy to maneuver, can turn on a dime, and deliver higher resale value
Before You Buy Your Next Boat, Think Twice.
You’ll Discover That Two Hulls Are Better Than One.
Compared to a monohull, a World Cat brings you greater stability and a smoother ride in virtually any type of sea.
Chances are, you own – or owned – a monohull boat. And that means you’ve endured pounding, slamming, and slapping. Monohull manufacturers employ deep V designs to try to lessen the abuse, but the result is often just more rocking and rolling whenever you stop or troll your boat. But a World Cat power catamaran offers you a better boating experience without all the exhausting physical abuse.
Why is a World Cat power catamaran superior to a monohull?
Because you get a smoother ride
– The wider footprint of a World Cat helps negate the effect of a rolling sea.
Because you get greater stability
– Unlike a monohull, you’re not pivoting on a centerline.
Because you eliminate the bumps and bruises
– The air tunnel created by our VectorFlo® hull creates an air shock absorber to smooth out your ride.
Because you can fish off the side
– The World Cat design allows the boat to gently drift sideways.
Because you get greater fuel efficiency
– You use less fuel because there’s less hull resistance in the water.
Because you get greater load capacity
– The wide deck of a World Cat also offers more room and comfort for you and your guests.
Because you can plane on one engine
– Which means you can get home with confidence in a World Cat.
Because you can go places a monohull can’t take you
– A World Cat’s shallower draft allows you to reach areas unreachable in a monohull.
Because World Cats are easier to pilot
– Turns are flatter and more stable than the leaning action of a monohull.
Because you get greater visibility
– Unlike monohulls, our decks remain parallel to the water at all speeds.
Because you get outstanding resale value
– Though, chances are, once you own a World Cat, you’ll never want any other boat.
Smoothness. Stability. Speed.
World Cat Hulls Are Designed To Deliver All Of Them.
When it comes to choosing the ideal boat, World Cat gives you more and better choices. It all begins with the two key hull designs that we offer. While each design shares the same major advantages of a power catamaran – a smoother ride, better stability, and shallower draft – our different hull choices can help you “fine tune” a better boating experience.
(used in all World Cat boats) – if you’re looking for speed, you’ll find it with this design. By employing a flatter V-bottom surface, you get on plane quicker for maximum speed. This design delivers racecar like performance. And, while traditional monohull boats slam you hard when coming down, this action is greatly reduced in a World Cat power catamaran. Which means less abuse and more control for you.
(used in our Glacier Bay Edition boats) – this design offers a softer ride, and has unique handling characteristics, which its thousands of satisfied owners swear by. Its unique design provides outstanding seakeeping and a soft ride by keeping larger sections of the hull in the water for maximum stability while underway. Its balance of hull buoyancy and dynamic lift reduces drag and increases efficiency.
World Cat Intelligent Hull Design –
The Science Behind The Smoother Ride.
World Cat boats deliver a smoother, softer, faster and drier catamaran ride in even the roughest, toughest conditions. The secret – and science – behind this better boating experience is intelligent engineering – which incorporates our VectorFlo® hull design.
This unique hull innovation combines air and water at the scoop-shaped bow and channels the mixture into the tunnel between the twin hulls. As part of the design, a Vector Pod, forward in the hull, helps to break up incoming water, creating aeration and reducing friction. As the mixture passes through the narrowing tunnel channel, it increases velocity, while decreasing forward pressure and drawing the aerated water and spray aft through the tunnel.
- The rapidly moving aerated mixture forms a water-cushioned suspension between the hulls and beneath the boat’s tunnel
- You get a softer ride, improved stability, and enhanced fuel efficiency
- Because the aeration increases in rough seas, the cushioning effect becomes more evident the worse conditions get
So, you get a better boating experience in all kinds of seas. But, don’t take our word for it, take a sea trial and experience the VectorFlo® advantage yourself.

How We Build The Perfect Hull.
The process of designing a catamaran hull is equal parts physics, experience and technology, and as it is a significant investment in time and resources, it needs to be done extremely well. Here, Greg McLogan, VP of Product Development, describes what goes into World Cat’s ‘secret ingredient’ – the hull:
- Before any design work is initiated, a full exploration of the boat’s intended use and desired performance characteristics is charted out. Will it be primarily used for fishing or for cruising? What speed, fuel economy and handling are desired? What type of ride is optimal (like cars, performance vs. ride is a balancing act)? What key features are critical? How can this boat be priced to maximize appeal? All factors need to be simultaneously solved.
- For example, a boat designed for fishing will have more livewell capacity, fish boxes and rod holders, and accessibility around the deck. A cruising boat will put a bigger priority on seating space, relaxing/refreshment areas and other creature comforts.
- Then, a general layout of weight and balance factors begins – what are the biggest weight contributors on deck, and how can these be optimally balanced around a center of gravity? How does this shift as people are added or as fuel is depleted? What engines are appropriate and how does their weight and power impact performance? How can stability be ensured if, for example, several fishermen are fishing from the same side of the boat?
- Once these basic priorities are identified, the hull design begins.
- Consistency/predictability across conditions.
- Amount of planing at certain speeds.
- Speed to plane.
- Angle at which hull reenters water after a wave (smooth reentry rather than pounding).
Catamarans generally have significantly greater planing characteristics than comparably sized monohulls.
- Factors in design:
- Distribution of deadrise (angle at which hull departs from centerline on hull): shifts from 35° in bow to 12° amidships, with the planing surface at transom.
- Shape of chines (deflects water in front; lifting surface aft).
- Required lift – defined by four core coefficients of form, boats have to have enough dynamic lift upward to overcome the weight of the boat and ultimately result in planing. This is accomplished by the number, location and shape of lifting chines and strakes.
- Planing surface (“delta pad”) – the flat surface that the boat rides on while planing. Catamaran planing surfaces are much more efficient than those on a monohull, which relies on lifting strakes to lift the boat. Instead, catamarans’ planing pads act like a lifting strake, which allows planing at lower speeds. The key to a great planing surface is the perfect balance of size, proportions, distribution, and how far forward on the hull it extends from the transom.
The defining aspect of a World Cat catamaran and the key to its advantages is the tunnel – as a unique situation where air is available underneath the boat , the resulting aerated water ‘cushion’ softens the ride.
- Key balancing act: a high tunnel accommodates more water but forces higher gunwale heights.
- Tunnel shape is designed to eliminate vibration and avoid ‘tunnel slap’ created by water movement.
- Critical to incorporate elements to aerate incoming water to reduce water friction. The Vector Pod, situated in the tunnel directly between the forward bows, is a key factor here.
- Also important to minimize ‘sneeze’ (the occasional forward puffing of water due to too much incoming water) – this is mitigated by downward deflection at the top of the tunnel in the bow.
- Importantly, need to design so that it can be built with sufficient durability to provide years of trouble-free enjoyment.
At WorldCat, we work to create the perfect balance between function and style:
- All design work includes the incorporation of essential features like anchors, through-hulls, doors, and motors.
- Functional factors, such as hull stiffness in critical areas and water deflection at the bow, are explored.
- Aesthetics are always a top priority, including everything from rubrail location to the way hull lines accommodate different colors.
At World Cat, we believe we have the industry’s best-performing hulls. But as we design new hulls, we continue to strive to seek out new shapes and materials to further improve the catamaran experience.
