In this article, I’ll review some of the best power catamarans out there. I’ll also go over the main features of different power cats and if they can handle rough weather. 

In this article you will find figures of top speed and cruising speed, it is important to note that theese numbers are given in good faith. Factors such as current, weight and dirty hulls impact boat speed.

But before we dive in, let’s get a better understanding of what power cats are.

What Is a Power Cat?

A power catamaran (power cat) is a motor-powered boat that, unlike traditional boats, has two hulls connected by a bridge deck. These vessels are more stable than monohulls because of their wide base. 

Power cats also don’t have a leaded keel to weigh them down, so they’re pretty lightweight and fast. The lack of a keel also means that power cats are more suitable for shallow waters.

They feature large engines designed to handle their bigger bodies and weights, and serve different purposes, like fishing, cruising, or crossing rough seas. In addition, each hull has a separate engine which makes them more maneuverable, especially at turns and tight spaces.

Power catamarans don’t have sails or masts and get all of their power from the combustion engine (or electric motor), unlike their sailing cousins. In addition, these vehicles are much easier to steer because of their increased stability.

Power catamarans have more interior and exterior space thanks to their multihull design, making them perfect for cruising and liveaboard. They also have ample space for storing everything you need on a cruise without worrying about weighing it down. Catamarans offer increased privacy as well because each hull houses one sleeping area, separated by the living area between them.

Are Power Cats Good in Rough Water?

Power catamarans are good in rough waters particularly because of their multi-hull design. Their wide base makes them stable, and their high speed allows for outrunning bad weather.

Power cats that feature a high bridge clearance, will handle rough waters effortlessly. With the added height, you won’t experience pounding and slamming even in heavy waves, allowing the crew to easily control the vessel in challenging situations.

These boats are also faster than their sailing counterparts, which means they can get you out of rough waters quickly.

In addition, since catamarans are large and tall, maneuvering is easier because you have a better view of the surroundings. Additionally, you can steer from the interior cockpit (on certain models), making it easier to control the vessel in bad weather.

Finally, although a power cat doesn’t have a keel to help it right itself in case of capsizing, it will still float easily because of its positive buoyancy.

Are Power Catamarans More Efficient?

Power catamarans are more fuel-efficient than monohulls because they don’t have leaded keels. While keels are designed to offer stability by weighing down the vessel, they increase the wetted surface and thereby add drag.

Due to the catamarans’ narrow bow entry, there’s lower resistance, leading to smoother acceleration and greater fuel economy in catamarans. In addition, power cats show fewer spikes in fuel consumption in a single power band, especially because of their smooth acceleration and fuel consumption.

The figures reported by cat owners or manufacturers show that power cats have the best power-consumption-to-speed ratios.

That being said, you can improve fuel efficiency by maintaining lower speeds; studies have shown that speed can be the most important factor in fuel efficiency, regardless of the number of engines or hull types.

Now that you have a better understanding of power catamarans, let’s take a look at the ten best models on the market.
