600°F Flameless Grilling on the Water — Built for Fiberglass, Engineered for the Sea
The only ElectriChef built-in configured for marine installation — Hardiboard insulation on sides and back makes it safe for fiberglass hulls, yacht galleys, and saltwater environments.
Most grills fail at sea before they get a season in — salt air eats through ordinary stainless, open flame is a fire liability near fuel vapors, and standard built-ins will crack a fiberglass hull from heat alone. The ElectriChef Emerald 24" Marine Built-In (model 4400-EC-336-IM-24) is purpose-built for exactly that environment. Hardiboard insulation on the sides and back protects fiberglass enclosures at operating temperatures up to 600°F. The 18-gauge 304 stainless body handles continuous offshore exposure. And the 3,520-watt digital electric system delivers full 336 sq. in. cooking performance — grill marks, a real sear, precise temperature — with no open flame, no propane stored below deck, and an auto shut-off timer that keeps things safe while you're moving around the boat. It ships fully assembled, drops into a 25⅝" × 16⅞" cutout, and connects to your 220V shore-power or onboard circuit.
What Sets the Marine Built-In Apart
Every specification here is chosen for one environment — on the water, in saltwater air, behind a fiberglass hull — where ordinary grills rust out, open flame is a safety liability, and performance still has to be worth the space.

Marine-Ready
Hardiboard Insulation — Safe for Fiberglass Installation
The defining difference between this model and the standard built-in is Hardiboard insulation applied to the sides and back of the grill body. This thermal barrier makes safe installation into fiberglass hulls and marine enclosures possible — protecting the surrounding structure from the grill's heat output at operating temperatures up to 600°F. A standard built-in grill without this insulation should not be installed directly against fiberglass.
304 S.S.
18-Gauge Stainless — Built to Survive Salt Air
Every surface is 18-gauge 304 stainless steel with a #3 finish — the same grade that handles continuous offshore saltwater mist without corroding. Ordinary grills deteriorate quickly in marine environments. ElectriChef's commercial-grade stainless is engineered to hold up underway and at the dock, season after season.
600°F
Full Searing Heat — No Open Flame Required
Reaches a genuine 600°F for deep grill marks and a proper caramelized sear — the outdoor grill experience you expect, without the open flame that fire codes, marina rules, and common sense prohibit on a boat. Even heat across the full 336 sq. in. cooking surface means every meal cooks at the temperature you set.
150–600°F
Digital Precision — Consistent Results Every Cook
The digital single-zone control lets you dial in any temperature from a gentle 150°F to a maximum 600°F sear. No hot spots, no flare-ups, no chasing the flame across a gas grate — just the temperature you set, held evenly across every square inch of the cooking surface.
10–60 min
Auto Shut-Off Timer — Critical Safety at Sea
Set the timer from 10 to 60 minutes and the grill shuts off automatically when it counts down. On a vessel where you may be moving between the cockpit, the salon, and the galley, an automatic shut-off is a genuine safety advantage — not just a convenience feature.
Dishwasher-Safe
Easy-Clean Grids and Drip Trays — No Mess Underway
All three stainless steel cooking grids are dishwasher safe — pull them out and rinse or load them in. Two removable grease trays lift out cleanly. In tight galley quarters where cleanup space is limited, that simplicity matters more than it does on a patio.

Deep Dive — Marine Built-In vs. Standard & Flameless Operation

Marine Built-In vs. Standard Built-In: Why the Insulation Matters
The Emerald 24" Marine Built-In and the standard Emerald 24" Built-In share identical cooking performance, controls, and 304 stainless steel construction. The marine model adds Hardiboard insulation on the sides and back — a thermal barrier that protects fiberglass, wood, and other marine hull materials from heat exposure during operation. It also has a slightly larger cutout footprint (25⅝" W × 16⅞" D) to accommodate the insulation panels, so it requires its own sized opening — a standard built-in cutout will not fit this model. If your application involves a fiberglass enclosure, a boat hull, or any marine-specific installation, the IM-24 is the correct specification. For land-based outdoor kitchen islands built from stone, tile, or steel, the standard built-in (4400-EC-336-I-24) is the appropriate choice.
Flameless Grilling: The Only Sensible Choice on a Boat
Open-flame grilling on a marine vessel — gas or charcoal — creates real fire risk at the dock and underway, and is prohibited in many marinas and harbor regulations. The ElectriChef Marine produces no open flame during operation. It connects to your vessel's 220V shore-power or onboard electrical system, reaches full grilling temperature, and shuts off automatically. No propane tanks stored below deck, no charcoal ash to manage in a rolling sea, no flame to expose to fuel vapors. Just plug in, set the temperature, and grill — wherever you're anchored.
Who It's For — The Deck & Den Take
▸
The Deck & Den Take — If you're outfitting a yacht, power boat, or sailboat galley, this is the grill that belongs there — not because it's the only option, but because it's the one specifically engineered for the job. The Hardiboard insulation on the sides and back is not a minor detail; it's what makes installation against fiberglass structurally safe. Before ordering, pull the spec sheet from the Documents section below and share it with your marine contractor. The cutout is 25⅝" wide by 16⅞" deep — notably larger than the standard built-in footprint — and your 220V circuit needs to be sized and positioned before the grill arrives. Get those two things sorted ahead of time and the installation itself is straightforward.
-
Yacht and power boat owners building or upgrading a deck galley where safe fiberglass installation, saltwater durability, and no open flame are all non-negotiable requirements.
-
Sailboat cruisers who want a compact, high-performance grill that fits a standard galley cutout, runs on shore power or an onboard 220V system, and handles real cooking at sea.
-
Marina and liveaboard owners in harbors or marinas where open-flame cooking on deck is restricted or prohibited — this grill complies where gas and charcoal grills cannot.
-
Waterfront homeowners building outdoor kitchen islands near the water where salt air demands 304 stainless throughout and a marine-grade installation approach.
-
Marine vessel designers and builders specifying galley equipment for luxury yachts and custom power boats where performance and installation safety are both required.
-
Precision-minded grillers on the water who want even heat, digital control, and repeatable results — not the variable performance of a gas grill rocking at anchor.

Frequently Asked Questions
▸
What makes the marine model different from the standard built-in?▸
The marine model (4400-EC-336-IM-24) adds Hardiboard insulation on the sides and back of the grill body, enabling safe installation directly against fiberglass hulls and marine enclosures. It also has a larger cutout footprint — 25⅝" W × 16⅞" D versus 24¼" × 16¼" for the standard built-in — to accommodate the insulation panels. Cooking performance, controls, and stainless steel construction are identical between the two models.
Can I install the standard built-in in a fiberglass hull instead?▸
No. The standard built-in (4400-EC-336-I-24) does not include the Hardiboard insulation needed for safe installation against fiberglass. For any marine or fiberglass enclosure application, the 4400-EC-336-IM-24 Marine Built-In is the correct model. Additionally, the cutout sizes differ — the two models are not interchangeable.
What are the enclosure cutout dimensions?▸
The enclosure cutout must be 25⅝" wide × 16⅞" deep. The overall outer width including the flange is 26¼". The grill accommodates surrounding tile ¼" to 1½" thick, no enclosure bottom or sides are required inside the cavity, and the power cord exits 9½" from the rear. Download the spec sheet from the Documents section above and share it with your marine contractor before cutting the enclosure.
What electrical connection does this grill require on a boat?▸
The grill requires a dedicated 208/220V, 20-amp, single-phase circuit with a NEMA 6-20R receptacle. On a vessel, this typically means 220V shore power or an onboard 220V electrical system sized for a 20-amp dedicated circuit. Have a licensed marine electrician wire the circuit before installation. The wiring diagram is available in the Documents section above.
Do you get grill marks with the ElectriChef?▸
Yes. The Emerald reaches a full 600°F, producing genuine grill marks and a proper sear. You get the full outdoor grill result — without charcoal, gas, or an open flame — regardless of whether you're dockside or anchored offshore.
Why is open-flame grilling a problem on a boat?▸
Open flame near fuel tanks, fuel vapors, and fiberglass creates a fire risk on any marine vessel. Many marinas and harbors also prohibit open-flame cooking on deck by regulation. The ElectriChef Marine produces no open flame during operation, eliminating both the fire risk and the regulatory barrier — while delivering full grilling performance from shore power or an onboard 220V circuit.
Can this grill be used indoors or below deck?▸
No. ElectriChef grills are designed for outdoor use only. This model is intended for installation in an outdoor deck galley or exterior enclosure on a marine vessel — not in an enclosed cabin or below-deck space.
Is there a performance difference between the 115V and 220V models?▸
No. Both voltage versions reach the same 600°F maximum temperature and deliver identical cooking performance. The 220V configuration is the standard for this marine model; confirm your vessel's shore-power or onboard electrical capacity before ordering.
How do I clean the cooking grids?▸
All three stainless steel cooking grids are dishwasher safe — remove them and load them directly, or soak in hot water with a strong dish detergent to loosen buildup. The two removable grease trays lift out for cleaning. For stainless exterior surfaces, use a non-abrasive stainless steel cleaner — especially important in a saltwater environment where residue can accelerate surface staining.
Are there any hot spots on the cooking surface?▸
No. ElectriChef's electric heating design produces consistent, even heat across the full 336 sq. in. cooking surface. Every part of the grate holds the temperature you set — no need to move food around for even results, which is a particular advantage when you're cooking on a vessel that may be moving.
Can I use wood chips for smoke flavor?▸
Yes. Place wood chips in a smoker box that rests on the cooking grates to add a light smoke note to your food. The grill operates without a flame, so the wood chips smolder rather than ignite fully.
Is a rotisserie available for this model?▸
Yes. An optional rotisserie kit is available separately from ElectriChef and is compatible with the Emerald 24" Marine Built-In.
How does the automatic shut-off timer work?▸
The digital timer is set from 10 to 60 minutes. When the countdown reaches zero, the grill shuts off automatically — a safety feature that is especially important on a vessel where the cook may be moving between spaces during operation.
What warranty does the Marine Built-In carry?▸
ElectriChef provides a tiered limited warranty honored directly by the manufacturer: lifetime coverage on stainless steel grill assemblies, 5 years on cooking grids, 3 years on the stainless steel heat-flavor plate, and 1 year on all other electrical and mechanical components. Labor is not included. Register your grill at electri-chef.com to activate coverage.
Does Deck & Den offer free shipping on this grill?▸
Yes. Deck & Den ships this grill free to addresses in the contiguous 48 states on orders over $100. Alaska and Hawaii are excluded from the free shipping policy.
