As a marine surveyor, I’ve inspected hundreds of boats over the past 15 years, from family cruisers to multimillion-dollar luxury catamarans. Some clients are thrilled when switching from monohulls to multihulls, while others are caught off guard by the differences and costs. I’ve also sailed these boats myself—delivering them across the Pacific, running charters in the Mediterranean, and doing coastal surveys from San Diego to Singapore.

1.Why Buy a Catamaran? Pros and Cons
According to Catamarans Market Size from Global Market Insights, the global catamaran market reached USD 4.7 billion in 2024 and is projected to grow at a compound annual rate of 7.4% from 2025 to 2034. That’s faster than the general boat market—proof that catamaran demand is rising much quicker than for monohulls. Their popularity isn’t a coincidence:
Comfort: Catamarans offer more space—typically 30–50% more interior volume than a monohull of the same length. With well-ventilated cabins, roomy cockpits, and abundant storage, living aboard feels effortless.
Stability: Twin hulls reduce heeling and motion, making life and long voyages more comfortable. Capsize risk is low, even in rougher weather—ideal for beginners, families, or ocean crossings.
Speed advantage: In light winds, catamarans are often faster than monohulls due to less underwater drag. For racing enthusiasts or anyone who loves speed, this is a big plus.
Shallow draft: Cats can anchor closer to beaches or enter shallow harbors—perfect for island hopping and exploring hidden coves.
Social lifestyle: Wide decks and central saloons are perfect for gatherings, barbecues, and entertaining.
But catamarans aren’t flawless, and smart buyers should weigh the drawbacks as well:
Higher costs: Expect to pay 20–40% more for a catamaran of the same length compared with a monohull. Maintenance, cleaning, and antifouling also double with two hulls.
Docking & marina space: Cats are wide, requiring larger berths. In popular marinas, this means higher fees and trickier maneuvering in tight spaces. Handling twin engines and steering takes practice.
Complex structure: Twin hulls and the bridgedeck mean more engineering. Repairs require higher skills and costs. Large cats are also harder to haul and transport.
Handling limits: Cats are steady in most conditions, but in extreme weather their large windage and less nimble handling can challenge even seasoned skippers. Comfort drops when wind and tide get aggressive.
In this market environment, I officially embarked on my own catamaran journey. As I mentioned earlier, my second vessel was a catamaran. After reading this comprehensive Oceanwalker S60 Luxury Catamaran Yacht Full Analysis, I purchased the Oceanwalker S60 Catamaran Yacht. Since acquiring it, I've truly experienced a level of comfort unmatched by monohulls. The spacious cabins, rock-solid deck stability, and exceptionally smooth sailing make every voyage an absolute pleasure.
2.Performance: How Do Catamarans actually Sail?
For sailors new to multihulls, performance is often the first surprise. The ropes and helm may look familiar, but once underway the rhythm is entirely different.
Speed: Cats can be fast—sometimes shockingly so. On a beam reach with a Catamaran used yacht, I once hit 16 knots—twice the pace of most cruising monohulls. Watching the speedo climb is a thrill.
Tacking: On a monohull, a crisp tack is a point of pride. On a catamaran, however, tacks tend to be slower. With no keel inertia, it’s easy to stall in irons. You need to bear away slightly, build speed, and then gently bring her nose through the wind.
Light winds: Don’t be fooled—cats aren’t lumbering beasts. With light displacement and large sail area, they can glide steadily in just 8 knots of breeze. With a Code Zero or gennaker, a cat sails like a silent seabird.
Heavy seas: When swells build, cats don’t slice through waves like monohulls—they ride over them. The broad stance keeps rolling minimal, providing a sense of stability even in rough seas.
3.Space and Layout Onboard
Step onto a catamaran and it feels less like boarding a yacht and more like entering a floating villa. Sunlight streams across wide decks, the bridgedeck rises gently with the waves, and the parallel hulls create a remarkable sense of space. On a typical 42-footer you’ll find:
Living areas: Expansive saloons, private cabin suites, and generous storage. I’ve surveyed cats with six separate lounging zones—deck, cockpit, saloon, flybridge, and twin aft transoms. With cabins isolated in each hull, it feels like everyone has their own apartment. Families and crews appreciate the privacy.
Galley & dining: Galleys often face the saloon, with ample counter space and storage. Big fridges, stoves, sinks, and neatly arranged lockers make cooking easy. Dining tables are roomy, with secure seating for comfort even underway. I recall a client’s wife laughing on her first cat trip: “Finally, we don’t have to cling to the table while eating!” That’s the difference cats make for family cruising.
Storage & equipment: Twin hulls add huge storage capacity for spares, sails, diving gear, and provisions—without intruding on living areas. A tidy, organized setup boosts comfort, safety, and efficiency.
In short, the space and layout on a catamaran don’t just look good—they shape the quality of life at sea, blending performance with comfort and privacy.
4.Upfront Costs and Long-Term Expenses
Sailing freedom comes at a price, and every yacht dream carries its bills. Beyond romance and open horizons, owning a catamaran requires facing the numbers honestly.
Purchase price: A 45-foot cat typically costs USD 650,000–950,000, depending on brand and options. Premium models may feature luxury interiors, automated nav systems, folding masts, and clever layouts. Wide hulls bring more comfort, but also higher price tags. Many new owners freeze when they first see the sticker—but one walk on deck and the value becomes clear.
Insurance: Expect premiums 20–30% higher than monohulls, thanks to:
Two hulls, two engines, and more electronics = higher replacement costs
Complex systems (nav, comms, power, automation) factored into risk
Broad coverage, often including salvage, theft, and natural disasters
Marina fees: Cats take more space, and some marinas charge by length + beam. Fees can be double those of monohulls. In popular harbors, wide berths are scarce, so early booking is essential.
Maintenance: More hull area, twin engines, twin rudders, multiple winches, and systems—everything doubles. Antifouling is pricier, and regular hull cleaning is routine.
Annual running costs: For a 50-foot cat in Phuket, annual costs (insurance, berth, maintenance) can approach USD 60,000. A safe rule: budget 10–12% of the yacht’s value per year. For a USD 700,000 cat, that’s USD 70,000–84,000 annually. Shocking at first, but soon it becomes part of the lifestyle cost of freedom.
Hidden extras:
Bridgedeck reinforcement on wide cats
Seal replacements in complex rig drives
Custom sails to fit wide beams
Extra safety gear for wider decks
Plan realistically, build running costs into your lifestyle budget, and financial stress won’t spoil your cruising dreams.
5.How to Ensure Safety at Sea
Catamarans are often marketed as “unsinkable”—and in some ways that’s true. With watertight bulkheads and inherent buoyancy, they’re far less likely to sink from hull breaches. They are indeed more stable than most designs. But let me be frank: stability is not the same as zero risk. To help you see both the strengths and the challenges, I’ve put together a quick guide to the key safety advantages and considerations when sailing a catamaran.
Although catamarans are generally stable, safety still depends on proper equipment and seamanship. On these vessels, security comes not only from design but also from preparation and practice. Here are a few essentials:
Redundant systems – Ideally, a catamaran should have twin engines, separate fuel lines, and independent bilge pumps. If one fails, the other can keep the boat functional and safe.
Harnesses and lifejackets – The wide decks may give a false sense of security. But in foul weather or at night, using tethers and wearing lifejackets is critical. The Coast Guard releases 2023 recreational boating statistics noted that drowning accounts for 75% of boating fatalities, and 87% of victims were not wearing lifejackets. The Coast Guard urges boaters to wear properly fitted and secured PFDs at all times.
Storm drills – Practice reefing, dousing sails, and securing gear ahead of time. Knowing how to act quickly under pressure is more valuable than any manual.
Mental preparation – Crews should understand that smooth sailing is the norm, but extreme conditions demand vigilance and teamwork. Running through emergency scenarios ensures calm responses when it matters.
6.What Maintenance Does a Catamaran Require?
When new owners think about maintaining a catamaran, their first reaction is often: “Two hulls? Twice the trouble?” The reality isn’t quite so scary. Catamarans do have unique requirements, but with attention and routine care, they’re often easier to maintain than expected. Maintenance isn’t simply “easy” or “hard” — some aspects are surprisingly convenient, while others can be tedious. Here’s a breakdown:
In short, maintaining a catamaran is a test of patience and thoroughness. Owners enjoy space and comfort but must invest more time and effort in repetitive tasks. By applying smart strategies—like those in 2025 Practical Tips: 6 Ways to Reduce Yacht Maintenance Costs—the workload becomes manageable, and the payoff is a safe, reliable platform for life at sea.
Conclusion
By now, perhaps you feel the same way I did the first time I stepped onto a catamaran: imagining yourself on that wide deck, steady underfoot, with open space all around. The 2025 catamaran market is reshaping what buyers expect. More and more sailors aren’t just seeking a way to travel under sail—they want lifestyle, leisure, and even a floating holiday home. Catamarans fit this vision perfectly.
Every decision to buy a yacht is the beginning of a new voyage. So the only question left is:
When will you step aboard?
