2026 Grady-White Marlin 300

The 2026 Grady-White Marlin 300 is a 30-foot sport fishing walkaround powered by three Yamaha engines. Built on the SeaV² hull design, it combines offshore capability with practical fishing functionality. The fiberglass construction and thoughtfully organized deck layout support serious anglers, with rod holders integrated throughout the hardtop, cockpit sides, and gunwales. A rigging station behind the helm includes a freshwater sink, bait box, and lockable drawers for tackle storage. The starboard side houses a 32-gallon insulated live bait tank with recirculating pump, while the transom features a 72-gallon fish bin. All decking is finished in non-skid surface for secure footing.

The helm station offers commanding visibility through a large ventilated tempered glass windshield and is equipped with a contoured seat and Yamaha electronic steering. Navigation and sonar are handled by a Garmin GPS map 1243xsv with Navionics Plus, a Garmin GMR 18 xHD radome, and full Yamaha Command Link integration to the Garmin network. A Sea Keeper ride system manages motion and improves comfort.

The forward cabin contains two berths and full galley amenities: microwave, ceramic cooktop, sink, 19-inch flat screen television with HDMI, vacuum flushing head with shower, and a Fusion sound system. Ample storage runs throughout both cabin and cockpit areas. Additional equipment includes a 5-kilowatt diesel generator, air conditioning, underwater lights, stainless steel delta anchor with swivel, and a full USCG safety kit. The boat is finished in Coastal Fog Blue gelcoat with matching hardtop underside.
