Marlin 300
30' WALKAROUND CABIN
In 1988, the Marlin 280 (today’s Marlin 300) was the first Grady with the exclusive SeaV 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.
