Marlin 300

30' WALKAROUND CABIN

In 1988, the Marlin 280 (today’s Marlin 300) was the first Grady with the exclusive SeaV^2® hull, offering amazing performance and true offshore saltwater fishing boat capability. Since that time, through customer input and attention to detail, Grady-White has refined every feature of this signature, much loved 30-foot walkaround cabin boat.
