Founded in 1959, Grady-White has long been known for building rugged, seaworthy boats designed for performance and comfort. The Marlin 300 stands as one of the brand’s most respected models - celebrated for its solid ride, smart layout, and versatility as both a serious fishing platform and a capable cruising vessel. This 1999 Grady-White Marlin 300 is a remarkable saltwater fisher that delivers on that legacy. 

The DOG HOUSE is powered by twin 225 hp 2006 Yamaha FX 225 TXR 4-stroke outboards with 1,246 and 1,248 hrs and is equipped with a full suite of electronics, including Icom VHF, a SIMRAD NSS8 MFD GPS/chart plotter, SIMRAD Hale radar,and a SIMRAD Robertson AP11 autopilot.

 A generous open cockpit features a 30-gallon standup livewell, a rigging station with tackle storage, an insulated fish box, and gunnel rod holders, an aft-facing bench seat w/storage, port & starboard outriggers, and an integrated swim/dive platform - with ample space for avid anglers and comfortable cruisability. Below deck, she easily sleeps four with a dinette/convertible double V-berth forward and a mid-cabin double berth, along with a full mini-Galley with a sink, a 1-burner stove, a Farberware microwave, and new NORCOLD refrigerator. Additional comforts include a new (2026) AC/heat system, a new FUSION stereo amplifier & sub-woofer speakers

and a separate enclosed head with shower.

First boat, next step up, or scaling back? This classic Marlin 300 delivers proven performance, comfort, and capability at an approachable price. A 2021 Rock & Roll tri-axle trailer and a 4-person liferaft are included in the sale. With several recent upgrades, and turn-key readiness, you will want to be in The DOG HOUSE for the 2026 season.
