We’ve been building catamarans for over two decades. When prospective owners ask us about liveaboard costs, we give them the numbers that matter — not the sanitized estimates you’ll find in glossy brochures. This breakdown comes from real conversations with our owners, actual marina receipts, the Noonsite cruising costs survey, articles about living aboard in Yachting World, and the unvarnished truth from Antares owners about what it costs to live on a high-quality cruising catamaran.
Before we get to the figures, understand this: your lifestyle choice matters more than your boat choice. A marina liveaboard in Fort Lauderdale will spend triple what a full-time cruiser anchoring in the Bahamas spends. Same boat, same systems, radically different budgets.
The Short Version: Your lifestyle choice matters more than your boat choice. Here’s what real liveaboard catamaran owners spend:
- Insurance runs 1–1.5% of hull value regardless of lifestyle (~$9,000–$15,000/yr on a $750K boat)
- Marina liveaboards spend 2–3x more than full-time cruisers on the same boat
- DIY competence is the single biggest lever on your annual costs — it can save 50–70% on labor
- Year 1 always costs more — budget an extra 20–30% for surprises
A Real Owner’s Budget: SV Unwritten Timeline
Numbers from cruising blogs are one thing. Numbers from an actual Antares owner are another. The crew of SV Unwritten Timeline published their detailed cruising budget — built around their Antares — with real line items and years of estimates. Here’s what they planned for:
| Category | Original Estimate | Revised Estimate |
|---|---|---|
| Boat loan | $1,600/mo | $1,076/mo |
| Boat maintenance | $500/mo | $500/mo |
| Fuel (diesel + propane) | $55/mo | $55/mo |
| Boat insurance (1% of $500K hull) | $420/mo | $450/mo |
| Country clearance fees | $200/mo | $200/mo |
| Health insurance | $100/mo | $100/mo |
| Communications (sat phone/SPOT) | $100/mo | $100/mo |
| Emergency savings | $100/mo | $100/mo |
| Total (ex-provisioning) | $3,075/mo | $2,581/mo |
A few things worth noting from their experience: insurance at 1% of a $500K hull ($450/month) tracks exactly with our estimates. Maintenance at $500/month is on the lower end — realistic for an experienced DIY crew in the early years, before major systems need replacement. Their communications budget predates Starlink; add $150/month for that today.
The Two Liveaboard Lifestyles
We frame everything around these two categories because they determine every other cost:
Category 1: Marina Liveaboard
- Stays in a marina 90%+ of the time
- Higher monthly costs (slip fees typically $800–$3,000+, depending on location)
- Less DIY required — yards handle most maintenance
- More predictable costs month-to-month
- Easy shore access, no generator dependence
Category 2: Full-Time Cruiser (Living on the Hook)
- Marina stays 1–2 weeks per year maximum
- Dramatically lower day-to-day costs
- Requires self-sufficiency (solar, wind, watermaker)
- More DIY maintenance — you’re the technician
- Less predictable — surprise repairs in remote locations
The DIY Gradient
Where you fall on this spectrum affects every maintenance number below:
- Full DIY — Saves 50–70% on labor. Requires skills, tools, and time. Many of our owners embrace this; Antares builds are designed for owner access.
- Partial DIY — You handle oil changes, cleaning, and simple fixes. Pay pros for rigging, electrical, and engine work. Most common approach.
- Full Yard Work — Most expensive, most predictable. You write checks, they keep the boat running. Typical for marina liveaboards without mechanical inclination.
Annual Cost Categories: Real Numbers
All figures are for a 44-foot cruising catamaran valued at $600,000–$900,000. We provide ranges for both lifestyles because the differences are substantial.
1. Insurance
This is non-negotiable and doesn’t vary much by lifestyle. The standard rule is 1–1.5% of agreed hull value annually, though we’ve seen premiums climbing toward 1.5–2% for bluewater coverage in 2024–2025.
- $600,000 boat: $6,000–$12,000/year
- $900,000 boat: $9,000–$18,000/year
Bluewater offshore policies extend coverage for ocean passages but cost more. Major providers who actually cover serious cruising:
- Pantaenius — Worldwide cruising, not available in US, “New for Old” settlement on partial losses, no depreciation on total loss
- Markel — Agreed value coverage, replacement cost on newer boats, P&I liability options
- Novamar — Specializes in Mexico and North America, works with A-rated carriers
- Concept Special Risks — Bluewater specialist with circumnavigation expertise
Key variables: Hurricane zone (Caribbean June–November) increases premiums significantly. One owner reported a jump from $9,000 to $16,000 for Caribbean summer coverage. Your experience level, claims history, and whether you require a surveyor’s sign-off all affect pricing. Older boats cost more to insure, even if hull value is lower — underwriters know 15-year-old systems mean bigger claims.
2. Slip/Anchorage Fees
This is where lifestyles diverge most dramatically.
Marina Liveaboard:
- US East Coast: $800–$1,800/month (Florida $14–25/ft; Northeast $12–20/ft)
- Caribbean: $1,200–$2,400/month. Green Cay Marina (St. Croix) charges $48/ft for multihulls. Bahamas marinas $15–30/ft depending on island.
- Mediterranean: €450–€2,200+/month. Italy and Spain surge 50–100% in summer. Greece is the bargain option at €30–€50/night for 12m catamarans in high season.
- Pacific (Australia/NZ): $1,000–$2,000/month
- Southeast Asia: $400–$1,200/month. Thailand (Krabi, Phuket) THB 525–920/ft. Malaysia RM 1,200–3,000 monthly. Singapore SGD 1,025–1,757 for members, 50% surcharge for catamarans.
Full-Time Cruiser (on the hook):
- Free anchoring: 90%+ of nights
- Occasional mooring balls: $5–$20/night
- Marina splurges for provisioning/weather: $200–$500/month averaged annually
- Annual total: $0–$3,000 (depends on how often you need refuge)
Antares note: Our 44s have a 21’9 beam. Some older marinas can’t accommodate you, and newer ones charge multihull premiums (typically 20–50% above monohull rates). Always confirm beam limits before planning long-term stays.
3. Maintenance & Haul-Out
The rule of thumb is 1–2% of boat value annually, but this varies enormously by DIY level and how hard you use the boat.
Annual haul-out:
- Lift, pressure wash, block, launch: $1,500–$4,000 depending on location
- US (Port Annapolis): ~$1,200–$1,600 for 44ft catamaran
- Turkey (Alanya): ~$1,280
- Caribbean (Marsh Harbor): $77–$94/ft for full bottom paint service
Bottom paint:
- DIY: $500–$800 (materials only)
- Professional: $2,000–$4,000+ (two coats, haul/launch included)
- Premium copper-free ablative: $100–$250/gallon
Engine service:
- DIY oil change, filters, impeller: $150–$300 per engine
- Professional: $500–$1,500 per engine annually
- Heat exchanger service, alternator replacement: Additional $800–$2,000
Rigging inspection/replacement:
- Annual inspection: $300–$600
- Standing rigging replacement (10-year cycle): $12,000–$25,000+ for 44ft catamaran
- Running rigging replacement (5–8 year cycle): $2,000–$6,000
Annual maintenance totals:
- Full DIY: $4,000–$8,000/year
- Partial DIY: $8,000–$15,000/year
- Full yard: $15,000–$30,000+/year
4. Fuel
Fuel costs split into three categories: main engines (diesel), generator (diesel), and dinghy (gasoline or outboard diesel).
Marina liveaboard:
- Minimal sailing, shore power available
- Generator use for off-grid power when dock power fails
- Annual diesel: $1,500–$3,000
- Annual dinghy gasoline: $300–$600
Full-time cruiser (self-sufficient):
- Minimal generator use if solar/wind sufficient (most Antares 44s run 400–800W solar)
- Diesel for motoring in calms, entering anchorages
- Consumption: 1.5–4 liters/hour at 6–7 knots (single engine)
- Marine diesel 2025 price: $3.50–$4.50/gallon
- Annual diesel: $800–$2,500 (depends on how much you motor vs. sail)
- Annual dinghy gasoline: $200–$500
5. Communications (Starlink, Cell)
Starlink Maritime (2024–2025 pricing):
- Hardware: $1,999–$2,500 one-time
- Monthly service (new 2025 plans): $150/month terminal fee + $1/GB for priority data
- Typical cruiser usage: 50–150GB/month = $200–$300/month
- Unlimited plans discontinued April 2025; throttled to 1Mbps after data cap
Cellular/eSIM:
- Airalo, Holafly, GigSky: $50–$150/month for multi-country coverage
- Google Fi: $20–$70/month but not suitable for extended cruising (suspended after 50 days abroad)
- Local SIMs in each country: $20–$50/month
Annual communications:
- Starlink + cellular backup: $2,400–$4,000/year
- Cellular only (coastal cruising): $600–$1,800/year
6. Medical/Health Insurance
Most liveaboards need international health coverage. US domestic plans rarely cover you abroad, and “travel insurance” has time limits.
- SafetyWing Complete: $150–$250/month (comprehensive, up to $1.5M coverage, no US coverage)
- Cigna Global (Silver/Gold): $300–$800/month depending on age, coverage level, and deductible
- IMG Marine/Gold: $200–$600/month for yacht crew and owners
Annual totals: $2,000–$9,600/year depending on age, coverage level, and whether you include US coverage.
Note: Some cruisers skip formal health insurance and self-insure, budgeting $5,000–$10,000/year for out-of-pocket medical. This works in countries with affordable healthcare (Thailand, Mexico, Eastern Europe) but is risky in expensive regions or for serious conditions.
7. Miscellaneous & Emergency Fund
The surprises that don’t fit in categories above:
- Customs/visas: $100–$500/year
- Diving (fouled anchor, stuck in sand): $50–$300
- Spontaneous repairs (watermaker, fridge, autopilot): $1,000–$5,000/year
- Flights home for family events: $2,000–$5,000/year
- Laundry, local transport, minor indulgences: $1,200–$3,000/year
Budget at least $5,000/year for “stuff happens.” The Bumfuzzle crew famously budgeted $1,500/month but spent $3,100/month average because of unexpected repairs (a $33,000 delamination issue on their first catamaran). Most experienced cruisers recommend a 10–15% buffer above your calculated budget.

Year 1 surprises:
- The boat needs things you didn’t notice during purchase. Budget an extra $10,000–$20,000 for “while we’re at it” upgrades: better anchor, solar expansion, watermaker, safety gear.
- Insurance is sticker shock. Many new owners expect car insurance rates. It’s 10–20x higher.
- Marina deposits and contracts. Annual commitments often required, with exit penalties.
Year 3 surprises:
- Systems reach end-of-life together. The fridge compressor, watermaker membrane, and outboard all fail in the same six months. Budget for clustering failures.
- Rigging replacement looms. If you bought a 10-year-old boat, year 3–5 means standing rigging at $15,000–$25,000.
- You’re more comfortable spending. What felt extravagant in year 1 (marina stays, dining out) becomes routine. Lifestyle inflation is real.
- You know what you actually need. The gadgets you bought in year 1 gather dust. Year 3 spending is more targeted and efficient.
Why Catamaran Costs Differ from Monohull Liveaboards
- Marina premiums: Catamarans pay 20–50% more for the same length slip because of beam. Some older marinas can’t accommodate you at all.
- Double the engines, double the systems: Two diesels, two saildrives, twice the maintenance. But redundancy means you’re rarely stranded.
- More living space = more systems: A 44-foot cat has the interior volume of a 55-foot monohull. More fridges, more air conditioning, more watermakers to maintain.
- Haul-out complexity: Cats need wider travel lifts. Some yards charge more or can’t handle you. Check before you commit.
- Resale value preservation: Quality cats like Antares hold value better than production boats. Your 1–2% annual maintenance investment protects a $750,000 asset. Poorly maintained monohulls depreciate faster.
Final Thoughts: What We’d Tell Our Own Family
If you’re serious about this lifestyle, budget for the “comfortable cruiser” category — $3,500–$6,000/month depending on your DIY capacity and geography. The $2,500/month figures you see on YouTube are possible, but they require extreme discipline, significant DIY skills, and tolerance for discomfort.
Most of our owners cruise 6–8 months a year and marina-hop the rest. Their actual spend falls in the $4,000–$7,000/month range for a fully equipped Antares 44i. The boat enables the lifestyle; it shouldn’t constrain it.
The best advice we can give: track every dollar for six months. Most people’s estimates are 30% low. Know your real numbers, then decide if you’re a marina person or an anchor person. Everything else follows from that choice.
