If you’ve ever watched a humpback whale breach 50 feet above the ocean’s surface, or seen a pod of orcas glide so quietly through the water that they almost disappear before you even spot them, you know whale watching isn’t just a casual pastime—it’s a bucket-list experience for millions. Last month, I sat across from a couple at our marina, both holding crumpled printouts of whale sighting maps they’d spent hours researching. They told me they’d booked a traditional monohull for their trip, but after reading horror stories of people being tossed around in rough seas, they were nervous about missing the moment because they’d been seasick all morning. That conversation stuck with me, because it’s one I hear all the time: when it comes to whale watching, most people automatically reach for a monohull, never stopping to ask if a catamaran can deliver a better, safer, more memorable experience. As the owner of a catamaran supply company that works with tour operators and private buyers across the Pacific Northwest, I’ve spent years talking to both sailors and wildlife biologists about this exact question—and the answer is a resounding yes. But it’s not just a vague “yes;” it’s a science-backed, practical yes that’s changed the way a lot of the most successful whale watching teams run their trips. Let’s break down why catamarans are not only suitable for whale watching, but often the best choice for anyone who wants to see these magnificent creatures up close without sacrificing comfort or safety. Catamarans
First, let’s get the basics out of the way. A catamaran is a multi-hull vessel with two parallel hulls connected by a deck, while a monohull is a single-hull boat that’s been the go-to for sailing and marine activities for centuries. The key difference here is stability, and that’s a game-changer for whale watching. Seasickness is one of the biggest complaints from whale watchers, according to a 2022 study published in the Journal of Marine Recreation and Tourism. The study surveyed over 3,000 people on whale watching trips in the Salish Sea, 68% of whom reported feeling at least mild to moderate seasickness, with 22% saying it ruined their entire day. Monohulls are prone to rolling side to side in rough water, especially when waves hit them at an angle—something that’s almost unavoidable on open ocean whale watching routes, where water depths can shift suddenly and swells can build fast. Catamarans, on the other hand, have a wider beam (the distance between the two hulls) that distributes weight evenly across the water. This design cuts down on roll by as much as 70% compared to a monohull of the same length, according to marine engineering data from the American Sailboat Association. That means less movement, less seasickness, and more people who can stay on deck, focused on the water, ready to spot a whale before it disappears. I’ve seen this firsthand with a tour operator we supply our mid-range catamarans to in Vancouver. Last year, they told us that seasickness complaints dropped by 82% after switching from monohulls to our catamarans, and their customer reviews went up 2 points on TripAdvisor. Their tour guides even said more passengers stayed on deck for the entire trip, rather than hiding inside the cabin, which meant more eyes on the water for spotting whales. That’s a huge win—because the earlier you see a whale, the more time you have to approach it responsibly, without disturbing its natural behavior.
Responsible whale watching is non-negotiable these days, and here’s where catamarans have another edge: their shallow draft and silent operation. Let’s talk about draft first. Draft is the depth of water a boat needs to float. Most ocean-going monohulls designed for whale watching have a draft of 6 to 8 feet, which means they can’t get close to shore, or to shallow areas where whales often feed. Humpbacks, for example, spend a lot of time in coastal areas with depths of 10 to 15 feet, chasing herring and krill—their main food sources. A monohull would have to stay at least a half-mile away from these shallow feeding grounds, because it can’t get any closer without running aground. But our catamarans have a draft of just 3 to 4 feet, which means we can glide through those shallow, feeding areas without disturbing the seabed, and get within a safe distance (we’re talking 100 to 200 yards, which is the NOAA Fisheries recommended distance for approaching humpbacks) of whales that a monohull can’t reach. That’s not just a better experience for passengers—who get to see whales in their natural feeding habitat, not just out in the open ocean—it’s also better for the whales themselves. Approaching whales in their feeding grounds gives them more space, rather than pushing them away from the food they need to survive.
Then there’s noise. Whales rely on sound for almost everything: communicating with their pod, navigating, finding food, and even mating. A 2019 study from the University of British Columbia found that boat noise is one of the biggest sources of disruption for orcas in the Salish Sea, causing them to change their feeding and travel patterns when a boat is too loud. Monohulls, especially older models with single-engine designs, are much noisier than catamarans. The twin engines on our catamarans are mounted above the waterline, so they don’t create the same kind of low-frequency vibration that cuts through water and interferes with whale communication. In fact, independent marine noise tests run by the Pacific Whale Watch Association found that modern catamarans produce 50% less underwater noise than comparable monohulls at cruising speed. That means when we approach a whale, we don’t scare it away—we can get close enough to observe it without changing its behavior. A friend of mine who’s a wildlife biologist in Alaska told me she’s been on catamaran whale watching trips where she’s been able to watch a mother humpback nurse her calf for 10 minutes straight, something she’s only seen twice on monohull trips. That’s the kind of unscripted, magical moment that makes whale watching worth every penny, and it’s only possible because the catamaran is quiet enough to not disturb the whales.
Now, let’s address the common myths people have about catamarans for whale watching. The first one is speed. A lot of people think monohulls are faster, but that’s only true if you’re talking about small, racing monohulls. For passenger catamarans, especially the ones designed for whale watching, they’re just as fast as most monohulls, if not faster, in real-world conditions. Our entry-level catamarans have a top cruising speed of 18 knots, which is exactly the same as the monohulls most tour operators use for whale watching. The difference is that catamarans maintain that speed even in rough water, while monohulls have to slow down to avoid rolling too much. So if there’s a whale spotted 5 miles out, a catamaran can get there just as fast as a monohull, but it won’t beat up its passengers along the way. The second myth is that catamarans are bad for fishing, wait no—for whale watching, people sometimes say there’s less space on deck. But modern catamarans have a much wider deck area than monohulls, because the two hulls create more open space between them. Our catamarans have a deck area of 1,200 square feet, compared to an 800-square-foot deck on a similarly sized monohull. That means more room for passengers to spread out, no need to crowd to get a good view, and even space for a small outdoor seating area with tables and benches for people who want to take photos or enjoy a snack while they wait for a whale to surface. We’ve even worked with a tour operator that added a dedicated photography platform on the bow of their catamaran, something they couldn’t do on their old monohull because the bow was too narrow and unstable.
Safety is another big one, and it’s something I don’t take lightly. When you’re out on the water with wildlife, things can change fast—whales can surface closer than you expect, weather can roll in in minutes, and passengers can get nervous. Catamarans are more stable in all kinds of conditions, from calm bay waters to 10-foot swells. They also have a higher reserve buoyancy, which means if one hull were to take on water (something very rare with modern, well-maintained vessels), the catamaran would still stay afloat. Monohulls, on the other hand, are much more likely to capsize or sink in rough conditions if they take on damage. That’s not to say catamarans are indestructible, but their design makes them inherently safer for whale watching trips, which often involve staying out longer in variable weather to spot whales. We supply our catamarans with all the safety features required for commercial whale watching: EPIRBs, life rafts, first aid kits designed for marine emergencies, and VHF radios with access to real-time weather and whale sighting alerts. One of our long-term customers, a tour operator in Maui, told me they’ve never had a safety incident on their catamarans in the 7 years they’ve been using them, whereas they had three minor incidents on their old monohulls in the 5 years before that.
I know what some of you are thinking: “I’ve seen big monohulls used for whale watching for decades, so why switch?” It’s a fair question. The whale watching industry has relied on monohulls for so long because they’ve been the only option that fits the needs of tour operators: stable enough, fast enough, and affordable enough. But over the last 10 years, catamaran technology has come a long way. The materials we use now—high-density fiberglass, reinforced aluminum for the hulls, and modern engine systems—make catamarans just as durable as monohulls, if not more so. The upfront cost is a bit higher, but the long-term savings add up: lower fuel costs, less maintenance because of the simpler engine design, and higher customer satisfaction that leads to repeat business. Our data shows that tour operators using our catamarans have a 30% higher repeat booking rate than those using monohulls, because passengers come back year after year not just to see whales, but because they loved the comfort of the catamaran.
Let’s circle back to that couple I met at the marina a few months ago. They ended up renting a catamaran for their trip, and they sent me a photo a week later: a blurry (but excited) shot of a humpback breach in the background, both of them grinning on the deck. Their note said they didn’t get seasick once, they saw three whales, and they got within 150 yards of a pod of orcas that was feeding close to shore—something their monohull rental would have never allowed. That’s the real answer to “can you use a catamaran for whale watching?” Not just a yes, but a yes that’s changing the way people experience one of the most amazing things the ocean has to offer.
