Overview

The Grady White Marlin 300 is a classic offshore walkaround boat that blends the features of an express fishing boat with the fishing amenities typically found on center consoles. Unlike many center consoles, it offers overnight accommodations, making it a versatile and family-friendly vessel. Measuring 30 feet 6 inches in length overall with a beam of 10 feet 7 inches, the Marlin 300 provides a spacious and stable platform for offshore fishing and extended trips.

Exterior Design and Cockpit

The Marlin 300 features a hull draft of 23 inches and a closed foredeck with a protected bridge and high windshield, which effectively shed green water in rough seas, ensuring a dry and safe ride offshore. The cockpit is designed with fishing in mind, offering 8 feet 10 inches of space from bolster to bolster and 6 feet 6 inches from the transom to the bait prep station, allowing ample room for multiple anglers to move and fish comfortably. The cockpit is 28 inches deep, with large bolsters and sturdy tow rails enhancing safety. Storage is well thought out, including rod storage under the gunnels and multiple rod holders on the cap rails and hardtop. The transom includes a door leading to a stern platform with a four-step ladder and grab rail for easy water access. Additional features include a freshwater shower wand, shore power connections, engine freshwater flush attachments, washdown hoses, battery switches, and circuit breakers housed in a dedicated compartment. The transom deck incorporates a cutting board over a storage compartment with pull-out tubs and battery storage below. A transom bench seat provides comfortable seating, and hatches grant access to the optional Fisher Panda 5 kW generator, pumps, seacock levers, water tanks, and a large insulated fish box.

Helm and Bridge Features

The helm deck is equipped with optional command chairs that are adjustable both vertically and horizontally, featuring ventilated backrests, swivel seats, flip-up bolsters and armrests, and fold-down footrests. Storage is integrated into the helm seats with locking drawers. The dash offers ample space for electronics and includes a Yamaha engine monitoring screen, compass, accessory switches, and a stainless steel tilt steering wheel. Controls for the twin Yamaha 300 horsepower V6 4.2-liter four-stroke outboards, trim tabs, stereo remote, and optional bow thruster are ergonomically positioned for ease of use. The fiberglass hardtop with a painted aluminum frame includes lockable storage boxes, storage nets, spreader lights, and opening side vents. Strata glass front and side curtains complete the enclosure, making the boat suitable for three-season use. Walk-around side decks with nine-inch bulwarks and tall rails provide safe access to the foredeck, which features a recessed design, a windlass with foot controls, a large hatch for the rode locker, and cushioned seating on the trunk cabin.

Interior Living Spaces

Below deck, the Marlin 300 offers comfortable accommodations suitable for overnight stays. The cabin includes a small galley to port equipped with a sink providing hot and cold running water, an electric stovetop set into a Corian countertop, a microwave, and a refrigerator. The bow features a dinette with a cherry wood table that converts into a V-berth. To starboard, there is an enclosed wet head with standing headroom, and a crawl-in mid-cabin contains a double berth, an opening port light, and rod holders. The interior is finished with a teak and holly sole and includes a six-gallon water heater and a 32-gallon fresh water tank, all standard equipment enhancing comfort and convenience.

Power and Performance

The test boat weighed an estimated 10,615 pounds with three people aboard, 39% fuel, and test power installed. Powered by twin 300 horsepower Yamaha V6 4.2-liter four-stroke outboards, the Marlin 300 achieved a top speed of 50 miles per hour at 5,900 RPM. The best cruise speed was 27.6 miles per hour at 3,500 RPM, delivering fuel efficiency of 1.5 miles per gallon and a range of approximately 390 statute miles with a 10% fuel reserve from its 282-gallon capacity. Acceleration was brisk, reaching planing speed in 3.3 seconds, 20 miles per hour in 3.9 seconds, and 30 miles per hour in 6.9 seconds. The hull’s 19.5-degree dead rise at the transom provided smooth handling through one-foot chop and 10-mile-per-hour gusting winds. Maneuverability was responsive and predictable, aided by the optional bow thruster and twin outboards, which facilitated easy docking and slip entry.

Conclusion

The Grady White Marlin 300 has been a mainstay in the brand’s lineup since 1989 for good reason. It offers a dry, secure, and comfortable platform suitable for families and anglers alike, combining offshore fishing capabilities with overnight accommodations. Its spacious cockpit, well-thought-out fishing amenities, protective design, and reliable performance make it a versatile vessel that meets the needs of a wide range of boaters. Overall, the Marlin 300 stands out as a well-rounded offshore walkaround that balances fishing functionality with cruising comfort.
