Among all the types of yachts, few have grown in popularity as dramatically as the catamaran. Once a niche choice, multihulls now dominate much of the charter market and have won a devoted following among cruisers and families. But what exactly is a catamaran, why have they become so popular, and how do they compare to traditional single-hull yachts? Here's a complete guide to catamarans, trimarans, and the multihull world.
What is a catamaran?
A catamaran is a yacht with two parallel hulls connected by a deck and superstructure, rather than the single hull of a traditional monohull yacht. The two hulls provide a wide, stable platform with the living space spread across a broad beam. Catamarans come as both sailing yachts and motor (power) catamarans, though sailing catamarans are the most common. A related multihull, the trimaran, uses three hulls — a main central hull with two smaller outriggers — for even greater stability and often higher performance.
Why catamarans are so popular
The catamaran's surge in popularity comes down to real advantages:
- Stability — two widely-spaced hulls make catamarans remarkably stable, with far less heeling (leaning) and rolling than monohulls. This means more comfort and less seasickness.
- Space — the wide beam creates enormous living space, with expansive deck areas, large salons, and cabins in each hull, often making a catamaran feel far larger than a monohull of the same length.
- Shallow draft — catamarans sit higher in the water, allowing access to shallow anchorages and beaches that deeper monohulls can't reach.
- Privacy — cabins in separate hulls offer privacy ideal for families or multiple couples sharing a yacht.
These qualities make catamarans especially beloved for cruising, charter, and family use, where comfort, space, and stability matter most.
Catamaran vs. monohull
The catamaran-versus-monohull debate is a classic in sailing. Catamarans win on stability, space, shallow draft, and comfort at anchor. Monohulls — traditional single-hull yachts — are often preferred by purist sailors for the classic feel of sailing, the way they heel and cut through waves, their performance to windward, and frequently a lower purchase price. Monohulls also fit in standard marina slips more easily, while catamarans' wide beam can complicate (and add cost to) dockage. Neither is universally better; it comes down to whether you prioritize the comfort, space, and stability of a cat or the traditional sailing feel and economy of a monohull.

Catamarans and chartering
Catamarans dominate much of the modern charter fleet, and for good reason: their stability, space, and privacy make them ideal for groups and families chartering for a week. If you're considering a yacht charter, a catamaran is well worth considering, especially for first-timers and those prone to seasickness, thanks to the stable, comfortable platform. Many people experience catamarans first through charter and become converts, later seeking one of their own.
The bottom line on catamarans
A catamaran is a twin-hulled yacht prized for stability, space, shallow draft, and comfort — qualities that have made multihulls one of the fastest-growing and most popular choices in yachting. While traditional monohulls retain devoted fans for their classic sailing feel and economy, catamarans have won over cruisers, families, and charterers in huge numbers. If comfort, room, and stability top your list, a catamaran deserves serious consideration, whether you're chartering for a week or searching for a multihull to call your own.
The downsides of catamarans
For balance, it's worth being honest about the catamaran's tradeoffs, because no design is perfect. Catamarans' wide beam, while creating wonderful space, makes dockage more challenging and often more expensive — many marinas charge extra for the width or have limited slips that can accommodate a multihull. The sailing experience differs from a monohull: catamarans don't heel and cut through waves the same way, which purist sailors may miss, and they generally don't point as high into the wind. Catamarans can also be more expensive to buy than a comparable monohull. And while modern cruising catamarans are very safe, their motion in certain sea conditions is different from a monohull's — a quick, choppy motion rather than a roll — which some people prefer and others don't. None of these is a dealbreaker, but a clear-eyed buyer weighs them against the considerable advantages rather than assuming a catamaran is simply better in every way.
The rise of power catamarans
While sailing catamarans are the most familiar, power catamarans — multihulls driven by engines rather than sails — are a fast-growing and increasingly popular category worth understanding. A power catamaran takes the twin-hull advantages of stability, space, and shallow draft and applies them to a motor yacht, without the masts and rigging of a sailing cat. The result is a remarkably stable, spacious motor vessel that's often more fuel-efficient than a comparable monohull motor yacht, since the slender twin hulls create less drag. Power catamarans have become especially popular for cruising and charter among those who want the comfort and space of a multihull but prefer motor yachting to sailing. They represent a meeting point between the catamaran's inherent advantages and the convenience of power, and they're an increasingly common sight in the world's premier cruising grounds, including the waters around Fort Lauderdale, the Yachting Capital of the World. For anyone drawn to the stability and space of a catamaran but uninterested in sailing, a power cat is well worth a serious look.
How catamarans went mainstream
It's worth appreciating how recent the catamaran's dominance is. For most of yachting history, the monohull reigned essentially unchallenged, and multihulls were viewed as exotic or niche. Over recent decades, however, improvements in design, construction, and understanding of multihull behavior transformed the catamaran into a mainstream, even dominant, choice — especially in the charter market, where their stability, space, and comfort proved ideally suited to groups and families sampling the yachting life. As more people experienced catamarans through charter and found them comfortable and approachable, demand for catamaran ownership grew in turn, and builders responded with an ever-expanding range of cruising and luxury catamarans. Today the catamaran is no longer the underdog but, in many cruising grounds, the default. This shift reflects a broader truth in yachting: comfort, space, and ease have steadily won converts, and the catamaran delivers all three. Understanding this history helps explain why, if you charter a yacht today, there's a strong chance it will be a catamaran.
