How Much Does a Catamaran Cost?

Catamaran Market Report — Q2 2026

Catamaran Market · Q2 2026 Patient Buyers, Priced-In Sellers Q2 2026 delivered a functioning but unhurried catamaran market: 58 boats sold at a median of $335,000, with the typical hull sitting more than six months before finding a buyer. By the Numbers 58 Boats Sold $335K Median Sold Price 90.6% Ask-to-Sold Ratio 197 Median Days on Market 45 ft Median Length 400 Active Listings The second quarter of 2026 painted the catamaran market in measured tones. Fifty-eight hulls changed hands, and among the 32 transactions with confirmed pricing, the median trade landed at $335,000 against an average of $363,098 — a tight gap that suggests the middle of the market is doing the heavy lifting, not the outliers.…

Yacht as a Business: Catamaran Guru’s Reality Check

“If you think a boat is an investment, you’re totally wrong. It’s a depreciating asset. It is the worst investment you could ever make.” That’s the opening salvo from Catamaran Guru in a long-form conversation that doubles as a masterclass on the yacht-as-a-business model — and a warning against the glossier pitches making the rounds in charter-ownership marketing. For a brokerage that represents Bali, Voyage Yachts, Fountaine Pajot, Leopard, Lagoon and more, and whose current inventory spans from a $61,650 project boat to a $3.6 million flagship, the message is refreshingly unpolished: a charter yacht can be a legitimate small business, a genuine tax shelter, and a route to a better lifestyle — but only if it’s run like an actual business.…

Catamaran Market Check-In: A Buyer’s Window, Not a Fire Sale

In his latest quarterly update, Wiley Sharp of Catamaran Central offers a grounded read on where the cruising catamaran market actually sits right now — and it’s more nuanced than the doom-scroll takes circulating online. Activity at his brokerage has picked up in the last quarter, and conversations with peer brokers echo the same theme: the market is uneven, but it’s moving. “Stop go, stop go,” is how Wiley describes the rhythm of the past year and a half. That inconsistency has become the new normal, and both sides of the deal are adapting.…

Secrets of the Great Loop with Curtis Stokes

The Great Loop isn’t something you dabble in. It’s roughly 6,000 miles of rivers, lakes, locks, coastlines, currents, weather windows—and decisions that matter. Today’s guest, Curtis Stokes, understands that kind of journey not just from theory, but from a lifetime on the water. Curtis grew up boating and fishing. He sailed the East Coast and the Bahamas long before most of us ever touched a helm—me included. That early pull toward the water became a lifelong calling. Curtis has captained vessels ranging from 75-foot classics to 180-foot superyachts, completed multiple circumnavigations, crossed the Atlantic more than half a dozen times, and logged countless offshore and inland miles.…

Scam Alert: Fake Buyers, Fraud Reports, and Emotional Manipulation

I have been banning fake buyers who run a specific type of scam. I have heard from multiple sellers who have experienced and fell for almost the exact same scheme. I’m sharing our stories here to protect other boat owners, especially those listing for sale by owner. The Scam: How It Works Scammers pose as interested boat buyers and reach out to sellers with questions that seem genuine. Over email, WhatsApp, or phone, they appear eager and knowledgeable—but their end goal is always the same: to trick you into buying a fraudulent “hull history” or “digital boat report” from a fake third-party website they control.…

Catamaran Structure – Bridge Decks and Cross Beams

Editor’s Note: Many thanks to Ted Clements of Antares Catamarans and Shane Grover of Seawind Catamarans for patiently answering our questions. There are a lot of reasons why catamarans are more expensive than monohulls. It’s not just the two hulls. There are many more complicated calculations and structures needed to build the complex shapes. Building a bridge deck and the structures around a pair of hulls is a lot more difficult to design and build than a single hull, and we’ll explore a little about why.…

Is a catamaran better for seasickness?

Unfortunately not based on my personal experience and watching others. That catamarans especially help with seasickness is a myth. In fact some catamarans seem to make seasickness worse because of their awkward, more unpredictable motion. I have sailed regularly the last decade thousands on miles in a variety of sea conditions on a variety of types of boats with a variety of crew. I also am prone to seasickness. While there is a difference in the motion of catamarans versus single hulled boats, the result for those who get seasick is usually the same.…

Catamarans are Better Than Monohulls

Frozen snotDescription of fiberglass boats by Lewis Francis Herreshoff It is not a debate anymore. People used to consider the advantages and disadvantages of cruising catamarans versus monohulls. Now it is simply a price consideration. “I don’t have enough money for a catamaran, so I am buying a monohull,” they lament. Catamarans have gone from 20% of the market in my home location of Fort Lauderdale to 50%. In the next decade they will go to 80% share of sailboats. They own the charter market.…

Should I Buy an Ex-Charter Catamaran?

I questioned 20 catamaran owners; if you were buying a used catamaran, would you consider a yacht from a charter company or only search privately owned vessels? 8 of the people said they wouldn’t consider ANY boat coming from the land of charters. Ten of the people said they would entertain the idea of buying a pre-owned charter boat and two already have purchased pre-owned charter cats and BOTH had good things to say about their experiences. Read on later in this article about specific experiences from one of the buyers.…

OceanVolt ServoProps – Perfect for catamarans but are they ready?

Not yet. But advancements are coming in the next decade, and the long awaited emissions free cruising dream is nearly reachable. It has been a long time coming. Countless sailors have pursued the impossible over the last decade as lithium batteries have been advanced and costs lowered. How many sailors have attempted to power the air conditioning from lithium and ended up with failure or anemic units which act more like dehumidifiers? With power hogs like air conditioners and electric motors, how many wind and solar keep up?…

Catamaran Construction – Hulls, Laminates, and Composites

It’s a given that catamarans are more sensitive to weight and loading than monohulls. Catamaran builders strive to build the lightest boats they can without sacrificing strength and stiffness, and have adapted new building techniques and materials to meet this target. Cutting weight allows more passengers and gear without sacrificing performance. And the marketing materials reflect it–they load every review and website with polysyllabic technical jargon describing the design and production choices each builder made to deliver the best boat they can.…

How much does it cost to dock a catamaran?

A big consideration when purchasing a catamaran is how much it will cost to moor or dock it. The cost to dock a catamaran will usually be higher than a monohull since their greater beam means they take up a lot more room than a monohull. The cost of moorage can vary greatly between different areas of the world however. Rates can also vary depending on the season (winter vs summer) if peak season is much more popular than the off-season. …

Should I Buy a Catamaran with Saildrives?

Catamaran buyers out there in the world have explicit demands and preferences when it comes to the layout of their catamaran. Things like dagger boards versus keels, Yanmar versus Volvo, flybridge versus bulkhead helms and the list goes on. A hot topic these days is that of the buyer of a straight shaft engine, or the other guy who would like a saildrive unit instead, on his catamaran. Traditionally, there are more straight shaft drive monohulls and more catamaran’s built with saildrives today.…

How much is a 45 foot catamaran? 5 Great Options.

Quick answer is $300,000 to $600,000. But you could also pay as much as $1 million for a fully loaded catamaran like La Vagabonde’s brand new Outremer 45 or as little as $150,000 for a late 1990’s Prout 45 or Leopard 45. These prices are all considering you are asking about a catamaran in reasonable condition and with appropriate cruising equipment. Project catamarans could end up costing much less initially although very likely much more eventually as typically you pay a premium in sailing for the “refit experience.”…

What are the parts of a catamaran called?

This article is a dictionary of sorts of common terms used whether slang or professional among catamaran sailors. balsa cored (adj.) – description of a type of building technique common on catamaran used for weight saving purposes. End grain balsa is sandwiched between two layers of fiberglass to stiffen, lighten, and insulate the hull and deck of many catamarans. Usually balsa coring is discussed in terms of concerns about water logged or “wet” coring material which is a significant expensive as well as a common issue especially as catamarans get older.…

Catamaran Drives Types – Outboards, Inboards and Drive Shaft Configurations

Catamarans these days have many options for their engine based propulsion, even more than monohulls due to the more diverse configurations of a catamaran. The traditional twin diesel engines is a popular arrangement, and dual or single outboard configurations are also becoming popular. When choosing an inboard engine, you then often have a decision to make in drive shaft configuration: traditional straight shaft, or a saildrive. The drive type has long lasting consequences for how you use and maintain a boat, so it’s an important factor.…

Why You Should Sell Your Catamaran For Sale By Owner

When a new salesperson starts in catamaran sales, often they start their journey to building a clientele by contacting for sale by owner sellers and trying to convince them into listing their catamaran on a brokerage basis. The process involves searching online for sellers on FSBO sites like this one and cold calling owners. In an ever more sophisticated internet world, this article questions the viability of brokering as a value additive for do it yourself sellers. Can these salespeople really offer something more than you can achieve on your own?…

What Size Catamaran Should I Buy?

The decision of what size catamaran to buy is an important one, and also a surprisingly difficult one. The best size catamaran will depend a lot on your needs for the boat – how you plan to use it, how many people you’ll typically have onboard, and what your expectations are for boating liveaboard life. A larger boat will be more spacious and comfortable for living onboard, capable of comfortably housing more people, but has higher costs for purchase and maintenance – and a larger catamaran can also require more skill (or crew) to safely sail.…

10 Best Pocket Catamarans (Under 38 ft)

Smaller cruising catamarans are an excellent entry level gateway into cruising catamarans and of late have become very popular. This is an effort to select some of the most well respected of these smaller catamarans. This was a difficult task, as many of these boats, designed and built some time ago, are still found in all the popular cruising grounds, and a list like this is subjective after all. All I can do is apologize in advance for leaving a boat off this list.…

Simple Accessory Voltage Regulator

(for battery operated devices) There are times when batteries in electronics are a pain in the butt, as they go dead at the most inconvenient times. Since a boat has a 12V battery bank and since our electronic gizmos run on a somewhat lower voltage, I thought a voltage regulator circuit was in order to have my boat battery bank run my electronics. There are a 100 voltage regulator circuits but I found that the least expensive solution was using a common 7805 fixed voltage regulator found at Radio Shack, it is possible to design a custom voltage output regulator for $2.00 which is current limited to slightly more than 1 amp.…

Fuel Additives for Marine Diesel Engines

Before EPA began regulating sulfur in diesel, diesel fuel contained as much as 5,000 parts per million (ppm) of sulfur. This sulfur was utilized by all diesel engine designs as a fuel system and injector lubricant. When the American EPA regulated sulfur out of Diesel fuel in 2006, this created a problem. All diesel engines were designed to use the sulfur in diesel fuel as a lubricant. Now it’s gone. I don’t know about you, but I certainly didn’t get the memo.…

Protecting your boat in a Hurricane

When a hurricane is forecast to head your way there are steps that should be taken to protect your boat. Look at the hurricane after photos here to see what happens when you don’t pay attention to anchoring in a storm. Hurricanes are the reason I only sail 11 months of the year here in sunny Florida. I sailed through one once (necessity) and didn’t like it very much. First step is always to reduce the boat’s windage by removing all sails, panels, Bimini.…

We have Pirate Treasure on our beaches!!

(NEWSER July 15, 2013) – “You may want to pack your snorkeling gear the next time you’re headed to Florida’s eastern coast. The owner of a shipwreck-seeking salvage company has announced that he discovered 48 gold coins worth as much as $250,000 off Wabasso Beach on Saturday. And as CNN reports, he made the find just 100 feet from shore, at a depth of just 6 feet. The coins seem to be in good condition, so much so that their dates can be read—they were made between 1697 and 1714…..”…

Women Love Catamarans

Women want to feel safe and secure When the decision is made to begin the search for the perfect boat, every one of us sits down and makes a list of the boat features and benefits that are important to us. When I did it, my check list of desired features lead me directly to cruising catamarans like the catamarans for sale by owner on this website. With their shallow draft, they were matching up to my sailing area better than a monohull and the research showed that Cruising Catamarans have a much brighter interior, (not a cave).…

Propeller Drag Under Sail Test

Propellers are a sailboat subject which sometimes turns into extremely heated exchanges when sailors gather and discuss propeller drag under sail. There are two schools of thought, of course. One school says that for best performance, propellers should be locked in reverse when sails are raised, and the engine(s) stopped. The other school of thought says that our transmissions should be put in neutral, and the propeller(s) allowed to free wheel while sailing with the engine off. This is of particular concern for us cruising catamaran owners as we have two propellers in the water and double the drag.…

Catamaran Design Formulas

Part 2: With permission from Terho Halme – Naval Architect While Part 1 showcased design comments from Richard Woods, this second webpage on catamaran design is from a paper on “How to dimension a sailing catamaran”, written by the Finnish boat designer, Terho Halme. I found his paper easy to follow and all the Catamaran hull design equations were in one place. Terho was kind enough to grant permission to reproduce his work here. Below are basic equations and parameters of catamaran design, courtesy of Terho Halme.…

Catamaran Hull Design

Part 1: Notes from Richard Woods Since the America’s Cup experimented with going multihull, there’s been a lot of interest in catamaran performance and the catamaran hull designs that define performance. Many guys are investigating whether to buy a catamaran or design and build their dream boat. Let it be said here that building a large catamaran is not for the faint of heart. People begin building 100s of boats a year, yet few are ever completed, as life always seems to have a way of interfering with a good boat build. …
