Premium Performance: The Granfort Boats 370 GTX
Some boats are built around a particular type of day on the water. The Granfort Boats 370 GTX takes a broader approach, combining the performance and capability expected from a serious offshore boat with the comfort, space, and amenities of a luxury cabin cruiser.
At 36.2 feet, the 370 GTX offers an impressive combination of open-air living space, cabin accommodations, twin outboard power, and the range to make longer adventures possible. Its design can support offshore fishing, cruising, entertaining, and extended time on the water without forcing owners to choose between performance and comfort.
For Unreel Marine, the Granfort 370 GTX represents something a little different from the typical center-console experience. It's a boat designed not just to get you somewhere, but to make the time spent getting there—and staying there—part of the experience.
Meet the Granfort 370 GTX
The Granfort 370 GTX sits within Granfort's Yacht Series, bringing a yacht-inspired approach to a 37-foot outboard platform. Its wide beam, fiberglass construction, open layout, cabin, and substantial fuel capacity give the boat a presence that goes well beyond its dimensions on paper.
Granfort describes the 370 GTX around three ideas: style, performance, and space. The spacious cockpit is designed for movement and comfort, while the open bow creates another area for relaxing and entertaining. At the stern, the twin-outboard configuration is integrated into the design while preserving usable space around the engines.
The result is a boat that can change roles throughout the day. Morning might mean running offshore to fish. The afternoon can become a swim, cruise, or lunch stop. And with the right equipment and options, longer trips can become just as comfortable as shorter outings.
It's a boat designed for the whole day - not just the destination.
Built for the Experience
The numbers behind the 370 GTX tell an important part of the story. The boat measures 36.2 feet overall with an 11.5-foot beam, a 20-degree deadrise in Granfort's published performance-test specifications, and a 222-gallon fuel capacity. The manufacturer lists a minimum draft of 1.97 feet and maximum draft of 2.46 feet, along with a 39.6-gallon freshwater capacity.
Granfort 370 GTX Specifications
Key published specifications include:
- Length: 36.2 feet
- Beam: 11.5 feet
- Draft: 1.9–2.2 feet
- Deadrise: 18°
- Hull Material: Fiberglass
- Fuel Capacity: 222 gallons
- Freshwater Capacity: 38 gallons
- Maximum Power: 800 HP
- Outboard Configuration: Twin 250–400 HP engines
- Published Passenger Capacity: Up to 14 during the day / 4 overnight
Those numbers help explain how the 370 GTX can serve several purposes without feeling like a compromise. The beam creates substantial usable space, the fuel capacity supports longer outings, and the twin-engine configuration provides the power and redundancy expected from a boat intended for serious offshore use.
A Fiberglass Foundation for Offshore Cruising
The 370 GTX is built around a fiberglass hull and a deep-V design intended to provide a stable, capable platform in open water. Granfort's published performance data comes from a fully loaded test configuration weighing 17,028 pounds with twin 400 HP Mercury Verado V10 outboards.
The boat's substantial dimensions and hull design give it the foundation for offshore cruising, while its outboard configuration offers some practical advantages for boaters who value accessibility and serviceability.
It's also worth remembering that performance on any boat depends on its final configuration. Engine selection, passenger load, fuel, equipment, sea conditions, and how the boat is operated all influence the actual ride and performance an owner experiences.
That combination of capability and flexibility is central to the 370 GTX.
Designed Around the Way You Spend Time on the Water
A boat this size needs to do more than provide a place to sit. The layout has to work when people are moving around, fishing, entertaining, relaxing, or preparing for a longer trip.
The 370 GTX approaches that challenge by dividing the boat into purposeful spaces while maintaining an open, connected feel.
Cockpit & Stern
The cockpit is one of the boat's primary social and functional areas, with Granfort emphasizing circulation and comfort. The stern accommodates the twin outboards while maintaining usable space around the engines rather than treating the power package as an afterthought.
For anglers, that open layout provides room to work around the boat. For cruisers, it creates a natural gathering area. Optional features such as an aft stool, table over the engine platform, additional rod holders, and upgraded audio can further tailor the space to the way the boat will be used.
Bow & Outdoor Living
Forward, the 370 GTX opens into a full bow area designed to accommodate up to four people. This gives the boat another destination within the boat itself—a place to stretch out while underway, relax at anchor, or enjoy an evening on the water.
Optional additions such as bow lighting, a bow shower, and a bow tent can make the forward space even more useful for extended days and overnight adventures.
Cabin Comfort & Amenities
The cabin is where the 370 GTX makes its strongest departure from a traditional center console. Rather than treating the cabin as a place to escape the weather for a few minutes, Granfort builds the boat around the possibility of spending meaningful time aboard.
Depending on the selected configuration, available amenities include air conditioning, a generator, electric stove, refrigerator, microwave, hot water system, cabin lighting, TV provisions, blinds, and a bathroom glass enclosure.
That range of options allows an owner to decide how much of the boat's luxury potential fits their lifestyle.
The 370 GTX isn't just equipped for a day on the water. It's prepared for whatever the day becomes.
Power, Performance & Range
A boat with the size and purpose of the Granfort 370 GTX needs power to match. Granfort designed the boat around twin outboard configurations ranging from 250 to 400 horsepower per engine, giving owners the ability to choose a setup that matches how they plan to use the boat.
At the top end, twin 400 HP outboards provide a combined 800 horsepower. In Granfort's published performance testing, a 370 GTX equipped with twin 400 HP Mercury Verado V10 engines reached a top speed of 51.1 mph with seven people aboard. That test provides a useful picture of the boat's performance potential, although actual results will vary depending on engine configuration, load, fuel, conditions, and operation.
Twin Outboard Power
Twin outboards give the 370 GTX more than raw horsepower. They provide independent propulsion, additional control around the dock, and redundancy that can be particularly valuable when traveling offshore.
The available 250–400 HP range also gives buyers flexibility. A pair of 250s may make sense for someone prioritizing efficient cruising and everyday use, while higher-output configurations provide additional acceleration and performance for boaters who routinely run longer distances or carry heavier loads.
The best engine package isn't necessarily the one with the biggest number. It is the one that makes sense for the boat's intended use, typical load, desired cruising speed, and range requirements.
Built for Long Runs
With 222 gallons of fuel capacity, the 370 GTX has the tank capacity expected of a boat designed for substantial coastal and offshore use. That matters when the destination is further away—or when a day on the water includes several stops rather than a straight run from the marina and back.
Range, however, should never be calculated from fuel capacity alone. Actual fuel consumption depends on engine selection, cruising speed, load, sea conditions, and how the boat is operated. Offshore planning should always include an appropriate reserve rather than treating every available gallon as usable range.
The same principle applies to freshwater. With nearly 40 gallons aboard, the 370 GTX can support longer outings and more comfortable time away from the dock, particularly when combined with its cabin amenities and optional systems.
What the 370 GTX Feels Like Underway
The 370 GTX's size, beam, and deep-V hull give it a substantial platform for open-water travel. A 20-degree deadrise is designed to help the boat work through offshore conditions while maintaining the stability and space expected from a vessel of this size.
But performance isn't simply about how fast a boat can run.
It's how confidently it accelerates, how it carries passengers, how it responds as conditions change, and how comfortable everyone remains after several hours underway.
That broader definition of performance is where the 370 GTX makes its case. It has the horsepower to move quickly when conditions allow, but it is equally focused on making longer trips enjoyable once the excitement of the initial acceleration wears off.
Technology, Electronics & Onboard Systems
Modern offshore boating depends on more than horsepower. Navigation, communication, entertainment, climate control, electrical systems, and safety equipment all contribute to how confidently and comfortably a boat can be operated.
The 370 GTX combines those systems with a helm and cabin designed around extended time aboard. Standard and optional equipment allows owners to determine how technologically equipped and self-contained they want their boat to be.
Helm & Navigation
Unreel currently lists a Simrad GO7 chartplotter and sounder as standard equipment, with an optional dual Simrad GO12 configuration available for boaters who want a larger electronics package.
For offshore use, the ability to monitor navigation information, depth, and surrounding conditions from the helm becomes increasingly important. A larger dual-screen arrangement can also make it easier to dedicate one display to navigation while using the other for sonar or other information.
The exact electronics package can be tailored to the owner's needs, making this another area where the 370 GTX can be configured for anything from comfortable coastal cruising to more serious offshore use.
Entertainment & Connectivity
The boat doesn't stop at navigation technology. Unreel lists a Fusion audio system among the standard equipment, with upgraded audio and additional speakers available as options.
That may sound like a small detail compared with 800 horsepower, but it's part of the broader Granfort philosophy. The boat is designed for people who intend to spend time aboard—not simply travel from one fishing spot to another.
Comfort, Electrical & Safety Technology
The 370 GTX can be equipped with systems that make longer stays aboard considerably easier, including air conditioning, a generator, hot water, refrigerator, electric stove, microwave, and additional cabin amenities. Safety-oriented options include fire suppression and other equipment designed to support the boat's offshore role.
Trim tabs, electric windlass equipment, underwater lighting, bow lighting, and other available systems further expand the boat's functionality.
These aren't features that exist simply to make a specification sheet look impressive. On a boat intended for offshore cruising and extended days aboard, the right systems can make the difference between a trip that feels like an adventure and one that feels like work.
Where the Granfort 370 GTX Fits
The 370 GTX occupies an interesting space for a buyer who wants more than a dedicated fishing platform but isn't ready to give up serious offshore capability. It's well suited to boaters who want to:
- Make longer coastal and offshore runs
- Fish without sacrificing comfort
- Bring family and friends aboard for extended days
- Entertain at the dock or on the water
- Spend nights aboard when the trip calls for it
- Configure the boat around a specific mix of cruising, fishing, and leisure
For the serious offshore angler, the 370 GTX provides the size, fuel capacity, power, electronics, and deck space to pursue demanding trips. For the family boater, the cabin, bow, cockpit, amenities, and seating create an entirely different experience.
It's not asking you to choose between adventure and comfort…it’s giving you both.
Final Thoughts
The Granfort Boats 370 GTX brings together the characteristics of a serious offshore vessel with the comforts that make spending a full day—or several days—aboard something to look forward to. Its substantial size, twin-outboard power, deep-V hull, generous fuel capacity, and modern electronics provide the foundation for confident coastal and offshore travel.
But the 370 GTX is about more than getting offshore. Its spacious cockpit, open bow, cabin accommodations, and available amenities give owners the flexibility to fish hard in the morning, cruise with family in the afternoon, and settle in for an evening on the water without feeling like the boat has changed purposes.
That's ultimately what makes the 370 GTX stand apart. It doesn't force an owner to define the boat by one activity. It's a platform for offshore adventure, fishing, entertaining, cruising, and simply enjoying more time on the water.
For boaters looking for a premium vessel that can grow with the way they use their time on the water, the Granfort 370 GTX offers an impressive combination of capability and comfort. Visit unreelmarine.com for more information and available options.
