Pontoon Boats: How Fast Can They Go and Should You?

When you think of speed on the water, your mind probably jumps to Unlimited Hydroplanes, those roaring beasts that skim across water like missiles. But on the opposite end of the spectrum sits the humble pontoon boat, known more for relaxed cruising and family outings than wild rides.

Yet in recent years, the question “how fast can pontoon boats go” has started to make waves. This top speed question comes especially from new buyers curious about using their pontoons for more than just lazy lake days. With modern design upgrades, twin Mercury engines, and larger engines available, the answer may surprise you.

So, just how much speed can a pontoon boat handle? Should you push it? And what are the trade-offs when you do? Let’s break it down.

What are Pontoon Boats?

The basics seems like a good place to start. After all, there are many types of boats. Some have good average speeds, some are fast as can be, and some are those which would never be accused of setting speed records.

Pontoon boats are some of the most beginner-friendly watercraft you can find. If you’ve ever seen a boat that looks more like a floating patio than a speedboat, you’ve probably seen a pontoon.

What Makes It a Pontoon?

The name “pontoon” comes from the boat’s design. Instead of a traditional hull, it floats on two or three large tubes—called pontoons. Generally, the size of the boat dictates the number of tubes in its design.

These tubes give it great stability. That means it doesn’t rock as much as a standard boat, making it perfect for relaxed cruising.

Room to Relax

Pontoon boats are all about space. Most have wide, flat decks with comfy seating, often like an outdoor sofa. There’s usually room for 8–12 people, depending on the size. Some models even have changing rooms, pop-up canopies, or mini bars. It’s like bringing your living room onto the lake.

Easy to Drive

Never driven a boat? A pontoon is a great place to start. They’re slow to moderate in speed and simple to steer. Most are powered by an outboard motor. You’ll find controls similar to a car, which makes it easier to manage at low speeds. They’re not built for racing, but they’ll get you where you want to go.

Perfect for Families

With high railings and stable floors, pontoons are a solid choice for families with kids or pets. There’s plenty of room for snacks, toys, coolers, and fishing gear. You can anchor and swim, cruise the lake, or just float and enjoy the sun.

Versatile Activities

Pontoon boats are surprisingly versatile. Want to fish? Add rod holders and a live well. Prefer tubing? Some models have powerful engines that can tow. Just want to sunbathe and chill? There’s no better platform. You can customize them with speakers, grills, lighting, and more.

Great for Calm Waters

Pontoons shine on lakes, slow-moving rivers, and bays. They’re not ideal for rough seas or big waves. But for calm inland waters, they offer one of the most comfortable rides out there.

Easy Maintenance

Pontoon boats are made with aluminum and vinyl—easy to clean and maintain. With basic care and winter storage, they can last for many years. Plus, parts are generally affordable and widely available.

Bottom Line

If you’re looking for a simple, relaxing way to enjoy the water, a pontoon boat is a great choice. It’s like a picnic table that floats—fun, low stress, and made for making memories.

The Truth About Pontoon Boat Speed

Now the reason you’re here.

A common misconception is that all pontoon boats are slow — more floating decks than watercraft. But today’s models are increasingly agile, with many hitting top speeds of 30 to 50 mph under the right conditions. In fact, the fastest pontoon boat on record topped out at over 114 mph!

While that’s not a number most riders will chase, the average pontoon boat speeds have significantly improved thanks to:

• Motors with higher horsepower
• Triple pontoon tubes (or “tritoons”)
• Improved fuel efficiency
• Lightweight, modern designs

As a general reference for speeds:

• A basic pontoon with a 50 hp motor will cruise at around 15-18 mph.
• A 150 hp pontoon can reach up to 35-40 mph.
• A high-performance setup with a 300 hp Mercury engine could exceed 50 mph.

Major Considerations Before You Chase High Speeds

Before you slam the throttle, it’s important to assess what kind of ride of your life you’re actually signing up for.

Weight & Load

A medium load of passengers (say, a few adults and gear) can significantly reduce max speeds. The boat’s weight, including pounds of people, fuel, and accessories, plays a huge role.

Weather Conditions & Water Type

Smooth water, like lakes good for water-sports will naturally allow for faster speeds than rough open waters. Watch out for wake zones and know the speed limit of your local waterways.

Safety Issues

With higher speeds come tight turns, increased risk, and the need for responsible handling. This is especially true if you have small children or very young kids aboard. Safety gear, seat placement, and experience all matter.

Type of Pontoon

A twin-engine boat or multiple-engine configuration gives you more zip. The number of pontoon tubes, hull design, and engine power directly affect your performance.

Fuel Consumption

Want higher speeds? You’ll need more fuel. So think about whether chasing speed is worth sacrificing fuel efficiency on long hauls.

Should You Aim for More Speed?

It depends on your real goal. Are you aiming for adrenaline? Towing slalom skiing enthusiasts? If so, a nice watersports rig might be a better choice. However, if you simply need a little guestimation aid to ensure the kids don’t get bored, read on.

Here’s a breakdown of what speed range suits different needs:

• 10–20 mph: Ideal for cruising, sightseeing, and family bonding. Safe for older teens, kids, and casual fun.
• 20–30 mph: Good balance for tubing, light water sports, and fun without too much fuel burn.
• 30–40+ mph: Great for adventure-seekers looking for a pretty adventurous ride. Requires skill, space, and awareness of safety issues.
• 50+ mph: Reserved for modified pontoons with special builds. Often impractical, expensive, and less comfortable.

What Type of Buyer Should Prioritize Speed?

If you’re using your pontoon for:

• Water sports (wakeboarding, tubing)
• Frequent travel on larger lakes (like Lake of the Ozarks)
• Hosting high-energy outings or teens

… then choosing a boat with more horsepower, larger engines, and a higher optimal speed makes sense. You’ll also want to ensure your pontoon is a model with modern design and features that allow fast boats to remain stable.

However, if your usage leans toward:

• Fishing
• Sunset cruises
• Leisure time with very young kids or pets

… then a specific boat tailored for calm, straight line navigation may suit you better — and save you on gas.

Final Thoughts: Don’t Generalize (Seriously)

The speed capabilities of pontoon boats can’t be summed up with a  generalization. It all depends on the engine, boat’s weight, load, water type, and your personal use case.

Want a little eye-opening truth? Many pontoon boat captains don’t even come close to using their boat’s full maximum speed. Most prefer a good average speed, cruising gently while enjoying their surroundings.

So, can pontoon boats go fast? Absolutely.

But should you go full speed? That’s up to you.

Before you buy, check price, compare engine specs, and talk to dealers about your specific needs. Whether you’re into various water sport activities, joy rides, or just catching some sun with a drink in hand, there’s a pontoon out there for you.
