Grady-White Express 370: BoatTEST Review
Overview
The Grady White 370 Express is a versatile 36-foot 7-inch blue water sports fisherman and family cruiser designed to accommodate both serious anglers and cruising families. With a beam of 13 feet 2 inches and a draft of 29 inches, this model serves as an excellent upgrade for center console owners seeking more fishing capabilities and comfort, as well as a practical downsizing option for owners of larger vessels. Its design balances functionality and comfort, making it suitable for extended offshore fishing trips or weekend family getaways.
Cockpit and Exterior Features
The heart of the 370 Express is its spacious cockpit, measuring 8 feet 10 inches wide and 6 feet 1 inch from the transom bolster to the bait prep station, providing ample room for three anglers to work simultaneously or for hosting social gatherings. A portside optional side door facilitates boarding from floating docks. The starboard bait prep station includes a 48-gallon insulated live well, a freshwater sink, and lockable tackle storage beneath. To port, an elevated seat with a footrest conceals either an electric grill or an optional 55-quart freezer. Additional features include a cutting surface with a trash/storage bin, a centrally located 291-quart insulated and refrigerated fish box with internal lighting and overboard drainage, and conveniently placed battery switches, fuel shutoff valves, and washdown hose. The transom houses a fold-down bench seat that swings up for easy access to seacocks, levers, tanks, and pumps, as well as a large hatch providing access to the standard 8-kilowatt diesel generator with a 23-gallon fuel capacity. Shore power connections and freshwater engine flushing ports are also located near the transom door. The foredeck features twin cabin hatches and a standard Lumar windlass with foot controls and a helm remote. Side decks are sufficiently wide with grab rails on the hardtop to aid forward movement. Optional outriggers and rod holders integrated into the hardtop frame enhance fishing capabilities.
Bridge Deck and Helm
The bridge deck demonstrates Grady White's commitment to functionality and family-friendly design. The full-height windshield, constructed of one piece of tempered glass within a structural aluminum frame, offers unobstructed visibility with a power vent at the bottom center. The raised centerline helm provides 360-degree visibility and features a deluxe platinum captain's chair with plush upholstery, swivel capability, fold-up bolsters, armrests, and adjustable height and fore-aft positioning. Starboard seating is highly configurable, accommodating up to four and a half people with options to convert between a dinette with a stowaway table, chaise lounge, settee, or forward-facing seat. To port, another raised seat complements padded gunwales leading to the cabin entry. The electronics panel is protected and raises at the push of a button, offering ample space for multiple screens. Additional storage includes a net beneath the steering wheel and lockable drawers in the starboard lounge seat base. The hardtop incorporates a sunroof, rod racks, two lockers, zippered life jacket storage, a secured first aid kit, and spreader lights for nighttime fishing. Optional hardtop upgrades provide further amenities.
Interior Living Spaces
Below decks, the 370 Express offers a well-equipped cabin with numerous standard features. The teak and holly sole adds a classic touch. To port, the galley includes a sink, electric glass stovetop, Corian countertops, refrigerator and freezer with ice maker, microwave oven, and abundant storage above and below the counters. Opposite the galley is a cozy dinette with a high-gloss cherry wood table that lowers to create a sleeping berth for two. A 28-inch flat-screen television is mounted on the aft bulkhead, accompanied by a full stereo system with six speakers and Bluetooth connectivity. The forward berth is fully separated by a privacy curtain and offers under-berth storage. A crawl-in mid-cabin located aft beneath the bridge deck provides a mattress large enough for two and includes six overhead rod racks. The boat features a stand-up head with a Vacuflush toilet and a separate shower stall, an uncommon amenity in this size class. Additional comforts include an 11-gallon hot water heater, 54 gallons of fresh water capacity, and a standard 16,000 BTU air conditioning system with vents both at the helm and below deck.
Power and Performance
The test vessel was powered by triple Yamaha 300 horsepower V6 4.2-liter four-stroke outboards, each turning 15.5 by 17-inch saltwater series 2 SDS stainless steel propellers. With two people aboard, 155 gallons of fuel, and test gear, the estimated test weight was 17,918 pounds. The 370 Express achieved a top speed of 48.3 miles per hour at 5,800 RPM. Its best cruise speed was recorded at 26.2 miles per hour at 3,500 RPM, yielding approximately one mile per gallon and a range of 313 statute miles with a 10% fuel reserve from the total 344-gallon capacity. Acceleration was brisk, with the boat planing in 3.8 seconds, reaching 20 mph shortly after, and hitting 30 mph in 6.9 seconds. Tested in mild conditions with about one-foot chop and 10 mph gusting winds, the boat exhibited a solid, stable ride that inspires confidence in rougher seas. Docking is facilitated by a standard bow thruster, with an optional Helm Master Joystick system available for enhanced maneuverability.
Conclusion
The Grady White 370 Express combines ample cockpit space, thoughtful family-friendly features, and robust offshore performance in a well-crafted package. Its spacious and functional cockpit, versatile bridge deck, and comfortable interior accommodations make it suitable for both serious anglers and families seeking weekend cruising adventures. Powered by reliable triple outboards and equipped with practical amenities such as a diesel generator, air conditioning, and advanced electronics, the 370 Express is well-prepared for blue water excursions and extended stays offshore.
