If you\u2019ve ever stepped onto a catamaran\u2014whether a sleek 28ft day charter or a 60ft bluewater cruising vessel\u2014you might have heard a lingering question from first-time buyers: \u201cAre these dual-hulled boats more likely to get damaged than my old monohull?\u201d As a catamarans supplier who\u2019s worked with these boats for over 12 years, I\u2019ve fielded this question hundreds of times, from weekend sailors upgrading to their first multihull to professional charter operators vetting new fleets. The short answer? No, catamarans aren\u2019t inherently more prone to damage than monohulls\u2014but their unique design creates specific vulnerabilities that most new owners (and even some experienced sailors) don\u2019t anticipate. Let\u2019s break this down with the kind of real-world insights we\u2019ve gathered at our yards, paired with naval research to back it up. Catamarans<\/a><\/p>\n

<\/p>\n

First, let\u2019s set a baseline: damage in recreational and commercial boats falls into two broad categories: accidental (collisions, groundings, grounding on debris) and structural (wear, tear, fatigue over time). For decades, monohulls have dominated recreational boating, so many of us default to comparing catamarans to the boats we grew up with\u2014but that\u2019s not an apples-to-apples comparison. Let\u2019s start with where catamarans actually hold a strength advantage. Their dual-hull design distributes weight across two narrower hulls instead of a single wide hull, which means they sit higher in rough water. For groundings, that\u2019s a huge win: a monohull\u2019s deep keel can punch into a sandy bar or rocky shoal at speed, tearing through fiberglass, damaging the keel, or even capsizing if it catches on a submerged object. I had a charter client last summer who ran his monohull aground on a shallow Florida sandbar at 8 knots; the keel sustained a 3ft crack and required $12,000 in repairs. Just two weeks later, a group in a 32ft catamaran ran aground in the same spot at 7 knots; their hulls only scratched the gelcoat, and they floated off at high tide with no damage. That\u2019s not an anomaly: a 2021 study by the American Boat and Yacht Council (ABYC) found that catamarans had 32% fewer grounding-related claims than monohulls of the same length over a 5-year period.<\/p>\n

Where catamarans do show higher damage rates, though, often comes down to design choices tied to their dual hulls. The biggest one we see is beam impact damage. Catamarans are wide\u2014typically 12 to 25ft wide, depending on length\u2014while most marinas, slip gaps, and lock entrances are designed for monohulls with a 8 to 10ft beam. A common mistake for new cat owners is underestimating that width when docking. I\u2019ve had a customer on a 38ft catamaran back into a slip in Annapolis, and the starboard hull scraped the piling hard enough to crack the hull\u2019s fiberglass laminate. Monohulls rarely have this issue, because their narrow beam fits easily into standard slips. Even worse: when catamarans are moored in tight spaces (like some old European marinas built for smaller monohulls), their upper hull structures\u2014like bridgedecks, trampolines, or bimini tops\u2014can swing into adjacent boats when winds pick up. We\u2019ve seen bimini tops torn entirely off and trampoline frames bent in half from 20+ knot gusts, damage that\u2019s far less common on monohulls, which have fewer wide, protruding structures near the waterline.<\/p>\n

Another underrated vulnerability: bridgedeck stress, especially on older or smaller catamarans. The bridgedeck is the flat structure connecting the two hulls, and it carries the weight of the cabin, engine, and any gear stored there. For decades, many smaller catamarans (built before 2000, roughly) used a single-layer fiberglass bridgedeck supported by thin bulkheads between the hulls. When these boats hit rough water\u2014especially head seas or quartering seas where the two hulls flex differently\u2014the bridgedeck can develop hairline cracks, or even delaminate from the hulls over time. We recently inspected a 1998 26ft catamaran that had spent 10 years cruising the Caribbean; the owner reported a \u201ccreaking\u201d sound after overnight gales, and we found a 18-inch delamination along the starboard bridgedeck-hull joint. Repairing that required grinding out the old laminate, adding a carbon fiber reinforcement layer, and re-bonding\u2014costing around $8,000. Monohulls don\u2019t have a comparable structure, so this type of structural damage is rare, but it\u2019s not unique to every new catamaran. Modern catamarans (built after 2010, in our experience) almost all use cored bridgedecks (usually balsa or foam core) and thicker laminate bonding, which cuts that risk by more than 60%, according to a 2022 report from the Multihull Industry Association (MIA).<\/p>\n

Then there\u2019s the area where catamarans are often falsely labeled as more fragile: collision damage. People hear \u201ctwo thin hulls\u201d and assume they\u2019re easier to puncture than a monohull\u2019s thick, reinforced hull. But here\u2019s the twist: most catamaran hulls are made with the same or thicker laminate than monohulls of the same length, because they don\u2019t need a heavy keel for stability. The MIA\u2019s 2021 damage claims report actually found that catamarans had 18% fewer collision-related damages than monohulls, when size and usage were factored in. That said, there is one exception: hull-to-deck joints. Catamarans have two hull-deck joints (one on each hull) instead of the single joint on a monohull. Over time, if not properly maintained, those joints can develop gaps from moisture, or cracks from repeated flexing. I had a client who skipped annual hull-deck sealant checks for three years on his 40ft cat; by the time he noticed, water had seeped into the joint, softening the fiberglass and leading to a small crack. Repairs there were more labor-intensive than a monohull\u2019s single joint, costing $5,500 versus $2,200 for a similar monohull. That\u2019s not a flaw in the catamaran design\u2014it\u2019s a maintenance oversight that\u2019s easier to make when you have two joints to check, not one.<\/p>\n

We also can\u2019t ignore user error, which is the root cause of most boating damage, regardless of vessel type. A new cat owner who\u2019s only ever skippered a monohull might not account for the catamarans\u2019 different handling: they\u2019re less maneuverable at low speeds, their windage is higher (meaning they drift more in crosswinds), and they take longer to stop. I once had a group of first-time cat owners hit a dock because they tried to reverse too quickly in a crosswind; the monohull they\u2019d owned before would have stayed closer to the dock, but the catamaran drifted sideways into the piling. That\u2019s not a catamaran flaw\u2014it\u2019s a learning curve that comes with any new boat, but it\u2019s steeper for multihulls because of their distinct design.<\/p>\n

Now, let\u2019s talk about long-term durability, because that\u2019s what matters most if you\u2019re considering a catamaran as a long-term investment. The MIA\u2019s 2023 study on multihull vs. monohull lifespan found that catamarans aged 15 to 20 years had similar structural integrity to monohulls of the same age, when both were properly maintained. The biggest factor for either boat isn\u2019t the type\u2014it\u2019s how well the owner follows maintenance schedules. For catamarans, that means checking hull-deck seals every year, inspecting the bridgedeck for cracks, and adjusting mooring lines to account for their wider beam. For monohulls, it means checking keel bolts and rudder components, which are unique to their design.<\/p>\n

So, to circle back to the original question: are catamarans more prone to damage? The answer is no, not inherently\u2014but they do have specific, design-related risks that owners need to plan for. If you\u2019re someone who docks in tight slips, cruises in crowded marinas, or skips routine maintenance, a catamaran might require a bit more attention to avoid damage. But if you\u2019re looking for a boat that\u2019s more stable in rough seas, less likely to ground, and offers more living space, the small added care is a trade-off that works for most of our clients.<\/p>\n

At our yards, we work with every kind of sailor\u2014from first-time buyers to experienced charter companies\u2014and we\u2019ve matched hundreds of people to catamarans that fit their lifestyle. We don\u2019t push every boat on every customer; if someone tells us they dock in a 20ft-wide slip and only sail in calm lakes, we might suggest a monohull. But for anyone who wants crosswind stability, extra space, and lower grounding risk, a catamaran is often the better choice\u2014with the right maintenance, you\u2019ll avoid most of the common issues people worry about.<\/p>\n
