Getting a Fridge, Washer, or Large Appliance Onto Your Boat

Appliances Are the Hardest Fit Problem on a Boat

Furniture you can disassemble. Mattresses roll. Appliances are sealed boxes that can't be shrunk, folded, or taken apart. A 27-inch washer has to come down the companionway at 27 inches — period. That's why most boat appliance upgrades start with a tape measure, not a shopping cart.

Before you buy anything, measure the entire dock-to-locker path: companionway, ladder, saloon, galley corner, and the locker cutout itself. If any one dimension is smaller than any appliance side, the appliance doesn't go in. See our dock-to-cabin delivery guide for the full path-measurement method.

Marine Fridges and Freezers

Top-Loading Boxes (Most Common)

Top-load fridges are built into cabinetry and accessed from above. They're rated by interior volume, but the external box is what matters for fit.

• 2.5 cu ft: 13 × 20 × 18" external — fits most 28+ ft cruisers
• 4 cu ft: 16 × 24 × 20" external — the standard liveaboard size
• 5–6 cu ft: 18 × 26 × 24" external — needs 35+ ft boat
• 8 cu ft: 22 × 30 × 28" external — yacht-only

Cooling is almost always DC (12V or 24V) with a separate compressor unit. Measure the locker opening and the path to it — a 20-inch-wide fridge won't go through an 18-inch galley corner.

Front-Loading Compact Fridges

More like a residential mini-fridge. 18–24" wide, 20–28" deep, 30–36" tall. Easier to install but harder to deliver because they're tall and rigid.

Drawer Fridges

Premium option on large motor yachts. 24" wide × 24" deep × 27" tall per drawer. Expensive, power-hungry, but they feel like a real kitchen.

Stoves and Cooktops

Propane Gimballed Stove (Traditional)

• 2-burner: 17 × 13 × 18" — fits in a 24+ ft galley
• 3-burner with oven: 22 × 19 × 20" — 32+ ft boat

Gimballed means the stove pivots to stay level while the boat heels — essential for cooking underway.

Induction Cooktop

• Single zone: 12 × 14 × 2" — drops into any counter cutout
• Dual zone: 23 × 14 × 2" — needs 30+ ft galley

Induction is the modern choice for liveaboards with lithium battery banks. No propane, no flame, no carbon monoxide risk — but your electrical system has to handle 1,800+ watts.

All-in-One Washer/Dryers

Combo ventless washer/dryers are the standard for liveaboard laundry. They wash, then dry in the same drum.

• Compact (24"): 23.5 × 22 × 33" — standard EU size; fits most 35+ ft boats
• Compact (18"): 17.7 × 22 × 27" — portable, sits on a counter; fits any boat

The 24" models have almost-residential capacity (2.5 cu ft). The 18" models handle 6–8 lbs per load — fine for two people if you run it every other day.

The ventless drying cycle takes 2–3 hours and uses a lot of power. Plan for shore power or a solid battery bank. Compare residential washer dimensions in our washer fit reference.

Water Heaters

• 6 gallon: 14 × 14 × 20" — typical
• 11 gallon: 16 × 16 × 24" — large cruiser / small yacht
• 20 gallon: 18 × 18 × 30" — full liveaboard

Most run dual-fuel: shore power element + engine heat exchanger loop. Install location is usually under a settee or in the engine room.

Dishwashers

Full-size dishwashers rarely fit on boats under 45 ft. Compact drawer dishwashers exist:

• Countertop compact: 17 × 20 × 17" — sits on a counter, holds 6 place settings
• 18" single drawer: 18 × 22 × 17" — built-in option for motor yachts

The Delivery Path for Heavy Appliances

A 24" washer/dryer weighs 150–200 lbs. A 4 cu ft fridge weighs 50–80 lbs. Moving these down a ladder requires at minimum two people and often a ramp or lowering strap system. Options for getting an appliance onto a boat:

• Companionway descent with two people — for items under 28" wide and under 100 lbs
• Deck hatch lift — remove the hatch and lower directly into the cabin with a line or davit
• Appliance dolly + ramp — for dock-to-cockpit only; do not wheel on non-skid
• Marina travel lift — lifts the appliance from the truck to the deck directly; best for 100+ lb items

Never attempt to carry a 200 lb washer down a ladder with one person. This is how both the washer and the person get hurt.

Measuring Before You Buy

1. Measure the destination locker (interior: W × D × H, plus ventilation clearance)
2. Measure the companionway clear opening with the hatch fully open
3. Measure the ladder width and pitch angle
4. Measure the galley approach width (the corner the appliance has to turn through once inside)
5. Run all four numbers through the ItemFits calculator

The single tightest point on the path is your maximum appliance size. Don't buy the biggest fridge that fits the locker — buy the biggest fridge that fits the path to the locker.

FAQ

Can I put a residential fridge on a boat?

Technically yes on large yachts; practically no on anything under 45 ft. Residential fridges are too wide for most companionways, too power-hungry for typical battery banks, and not designed for heel angle or humidity.

Do I need a gimballed stove if I only cruise in calm water?

No. Dock-only and protected-water liveaboards often use fixed induction cooktops. Gimballed stoves are specifically for boats that cook while sailing in rough seas.

What's the biggest washer that fits a typical 40 ft cruiser?

A 24" EU-size combo washer/dryer (23.5" wide, 33" tall). Anything larger usually doesn't make it through the companionway. Plan delivery through the deck hatch if the companionway is under 24".

How much power does a marine all-in-one washer use?

1,800–2,400 watts during the dry cycle, for 2–3 hours. That's 4–7 kWh per load — meaningful for battery-powered boats. Many liveaboards run the washer only while on shore power.
