Author’s Note: The author of this article is an amateur blogger from Europe and the U.S. with 12 years of experience in recreational boating. He has owned and operated two catamarans: namely a 2015 Lagoon 42 and a 2021 Fountaine Pajot Elba 42, and has participated in three transoceanic voyages as well as dozens of short-distance recreational cruises.The content of this article is based on personal, firsthand experience and publicly available industry data; there are no commercial conflicts of interest, and the review is independent and objective.
First, the conclusion: Is a catamaran right for you?
To be honest, there’s no standard answer to this question.
The key is to be clear about what you want.
Below, I’ll lay it all out—the pitfalls I’ve encountered and the lessons I’ve learned the hard way.
What exactly are the advantages of a catamaran?
Stability.
I’ve repeated this word countless times, but it’s truly worth saying again.
My first catamaran—a Lagoon 42—was purchased in 2015. My first offshore voyage was from Miami to the Bahamas. The waves that day were about 1.2 meters high.There was a time when, facing waves of that height on a monohull, I’d be so nervous that my hands would sweat through the helm. But on this catamaran? You could barely feel any roll.
That’s the biggest advantage of a catamaran: stability.
Virtually no rolling while sailing
The deck remains level while moored, so walking doesn’t feel wobbly
Great for those prone to seasickness (my wife is a prime example)
Spacious.
This is another key selling point.
For boats of the same length, catamarans offer 30 to 50 percent more interior space than monohulls. Why is that? The reason lies in the flybridge area between the two hulls—an area that simply doesn’t exist on a monohull.
My 2021 Fountaine Pajot Elba 42—my second boat—is approximately 12.5 meters long and features the following interior layout:
| Area | Monohull (same length) | Catamaran |
|---|---|---|
| Main Cabin Headroom | Approx. 1.9 meters | Approx. 2.1 meters |
| Number of bedrooms | 2 | 4 |
| Number of bathrooms | 2 | 4 |
| Deck living space | Approx. 15 square meters | Approx. 35 square meters |
Data is sourced from the BoatUS 2023 Boat Space Comparison Report and was derived from actual measurements.
Fuel-efficient.
Many people are unaware of this.
Because catamarans have a narrower waterline, they experience less drag than monohulls of the same length. This means:
Fuel consumption is reduced by approximately 20%–30% at cruising speed
With the same amount of fuel, they can travel farther
Lower long-term ownership costs
According to data released by the Yacht Manufacturers Association (YMA) in 2024, based on 200 hours of sailing per year, the average annual fuel cost for a catamaran is nearly $2,400 lower than that of a monohull.
However, catamarans also have their drawbacks
They’re expensive.
This is the most obvious drawback.
For boats of the same length, catamarans typically cost 1.5 to 2 times as much as monohulls.
I purchased my first Lagoon 42 in 2015 for approximately $650,000. For monohulls of the same era and class with comparable specifications, prices generally fell within the range of $350,000 to $400,000.
Mooring costs are high.
Catamarans are characterized by their greater width; generally, a 12-meter-long catamaran has a width ranging from approximately 7.5 to 8 meters, whereas a monohull of the same length typically has a width of only 3.5 to 4 meters.
This means:
higher docking fees (charged based on width)
Many docks cannot accommodate them
Special permits are required for trailer transport
When I was switching boats for the second time, I almost gave up on the idea of a catamaran because of issues with docking.Shortly after, I found a dock in Florida specifically designed for catamarans, but the monthly fee there was 2.3 times that of a typical dock.
Deep draft.
Because catamarans have two hulls, their draft is usually deeper than that of monohulls.
My Lagoon 42 has a draft of about 1.5 meters, while a monohull of the same length has a draft of about 1.2 meters.
This means:
Restrictions in shallow waters
Greater caution is required when docking
Inability to enter certain bays
Maintenance is more complex.
Two hulls, two sets of engines, and two steering systems.
Maintenance costs are naturally higher.
According to the BoatUS 2023 Maintenance Cost Report, the average annual maintenance cost for catamarans is approximately 18 percent higher than that for monohulls. Major expenses include:
Engine maintenance (two sets)
Hull inspections (two sets)
System redundancy (more)
Common Pitfalls for Beginners
Pitfall #1: Assuming that catamarans can never capsize.
This is the most dangerous misconception.
Catamarans are indeed stable, but they are not immune to capsizing.
In 2019, a catamaran capsized off the coast of Florida because the owner insisted on sailing despite severe weather conditions. Although the vessel was wide, its center of gravity was high, so it remained at risk when wind and wave conditions became too intense.
Remember: Catamarans are not invincible.
Pitfall #2: Underestimating the difficulty of mooring.
I’ve seen too many beginners who, after buying a catamaran, find they can’t locate a suitable dock.
Many older docks in Florida were designed for monohulls and aren’t wide enough. You need to do your research in advance:
the width of marinas along your intended route
Route restrictions for trailer transport
Temporary mooring options
Pitfall #3: Ignoring maintenance costs.
Catamarans have more complex systems.
Two engines, two rudders, two propellers. During maintenance, you need to:
monitor both sets of systems simultaneously
Higher spare parts costs
Longer repair times
Recommendation: Before buying a catamaran, calculate your average annual maintenance budget carefully.
My Experience
Ideal for:
Families (who need plenty of space)
People prone to seasickness
Those with a generous budget
Primarily sailing in calm waters
Not suitable for:
Those on a tight budget
Frequent visitors to shallow waters
Those who enjoy a thrilling driving experience
Primarily for single users or small families
My recommendation:
If you’re on the fence, start by renting a catamaran to try it out.
I recommend renting one in Miami, Florida, for a 3- to 5-day trip. Give it a try:
Difficulty of docking
Maintenance complexity
Sense of actual space
The cost of renting a boat—approximately $1,500 to $3,000 per week—is much lower than the trial-and-error costs involved in buying one.
Q: Which is safer, a catamaran or a monohull?
A: It depends on the situation. Catamarans offer good stability and are less prone to capsizing; however, their center of gravity is higher, which increases the risk in severe weather. Monohulls have a lower center of gravity and are more resistant to wind and waves. According to data from the U.S. Coast Guard, the accident rate for catamarans is slightly lower than that for monohulls, but the proportion of serious accidents is comparable.
Q: Are catamarans suitable for long-distance voyages?
A: Yes, they are. I set sail on a catamaran in 2018, departing from Florida for the Bahamas. a journey of approximately 120 nautical miles that took two days. Catamarans offer significant advantages in terms of comfort during long-distance cruising. However, it’s important to note that while fuel efficiency becomes more pronounced on long voyages, berthing costs are also higher.
Q: Is maintaining a catamaran really more difficult than a monohull?
A: Yes. Having two sets of systems means twice the workload.I spend about 40 more hours per year on maintenance compared to my friends who sail monohulls. However, the benefit is that the systems are redundant—if one fails, the other can still function normally.
Q: Is it a good deal to buy a used catamaran?
A: It depends. Catamarans depreciate more slowly than monohulls.According to the NADA Boat Value Report, the residual value ratio for catamarans after five years is roughly 65%, while that for monohulls is approximately 55%. However, inspecting a used catamaran is more complex, so it’s recommended to seek out a professional boat surveyor.
Q: Are catamarans suitable for fishing?
Not really.Catamarans have wide decks and excellent stability, which means your fishing line is less likely to drift off course. Additionally, catamarans have a deeper draft, making them unsuitable for fishing in shallow, nearshore waters. If fishing is your primary activity, a monohull might be a better choice.
In conclusion:
Catamarans are not a one-size-fits-all solution.
They’re suitable for specific people and specific situations.
Before buying, think carefully about your needs.
Don’t be swayed by advertising.
Don’t let your friends’ recommendations sway you.
Your boat, your lifestyle.
Choose the right one, and you’ll love it. Choose the wrong one, and you’ll regret it.
Good luck.
