A catamaran sounds like the easy choice the first time you step aboard one — flat decks, no heeling, a cockpit you can actually walk across without grabbing a handrail. That’s all true. It’s also a different boat than a monohull in almost every way that matters once you start shopping, from what it costs to where it can dock. Here’s what actually matters before you buy your first catamaran.
Why Buyers Choose a Catamaran in the First Place
Two hulls mean stability at anchor and underway — catamarans don’t heel the way monohulls do, which matters a lot if seasickness or nervous guests are a factor. They also draft much less water, so shallow anchorages and skinny channels that would ground a monohull are open to you. The tradeoff is width: a 40-foot catamaran can be 22 feet wide, which limits which marina slips fit it and usually costs more to dock.
What Size Actually Makes Sense
- 35-40 feet — the realistic entry point for a couple or small family; manageable to sail short-handed, easier to find slips for
- 40-45 feet — the sweet spot for liveaboard or long-range cruising; enough space for guests without needing extra crew
- 45+ feet — comfortable but starts requiring real crew experience or hired help, and dock fees climb fast at this width
Bigger isn’t automatically better. A 45-foot cat with two people aboard means more boat to maintain, more sail to handle, and a narrower set of marinas that will take you.
What You’ll Actually Pay
Used catamarans in the 35-40 foot range typically run $100,000 to $250,000, depending on age and condition. Step up to 40-50 feet and used prices land between $250,000 and $700,000. New boats from the major production builders — Lagoon, Leopard, and Fountaine Pajot — start around $300,000 to $450,000 for their smallest models and climb well past $1 million for larger or more upscale layouts.
The purchase price is the easy part to plan for. Ownership costs are what catch first-time buyers off guard: insurance runs 1-2% of the boat’s value per year, maintenance another 10-15%, and dock fees alone can run $1,000 to $5,000 a month depending on location and the boat’s width. A $300,000 catamaran can easily cost $40,000-$50,000 a year before you’ve sailed anywhere. For broader boat-ownership guidance, BoatUS is a solid resource.
New vs. Used
A new catamaran from Lagoon, Leopard, or Fountaine Pajot comes with a warranty, current electronics, and no mystery maintenance history — but you’re paying full retail and the first few years of depreciation are steep. A used boat, especially one coming out of a charter fleet, can be a third of the price of new, but charter boats are sailed hard and need a harder look at rigging, engines, and structural condition before you commit.
Either way, never skip the survey. A marine survey and sea trial costs $1,500 to $3,000 and will surface problems — delaminated decks, worn rigging, engine issues — that aren’t visible on a walkthrough. On a six-figure purchase, that’s the cheapest insurance you’ll buy all year. The same logic applies on land — when buying a used performance car, a pre-purchase inspection is just as non-negotiable.
Questions to Ask Before You Buy
- Has it been privately owned, or did it come out of a charter management program?
- What’s the engine hour count on both motors, and when were they last serviced?
- Has the standing rigging ever been replaced, and is there a record of it?
- What marina or mooring will actually fit this boat’s beam near where you plan to keep it?
- Is there evidence of osmosis, delamination, or prior structural repair?
The Bottom Line
A catamaran buys you stability, shallow-water access, and space — at the cost of a wider boat, pricier dockage, and a steeper total cost of ownership than the sticker price suggests. Size down before you size up, always get a survey, and budget for the marina before you budget for the boat.
Recommended Gear
A few items worth owning before you start walking docks and scheduling surveys:
- Marine moisture meter — the same tool surveyors use to find wet core in decks and hulls; useful for pre-screening boats before you pay for a full survey
- Handheld VHF radio — you’ll want your own for sea trials, and it’s required safety equipment you’ll keep for the life of the boat
- USCG-approved life jackets — buy your own rather than trusting whatever mildewed set comes with the boat
