Grady-White Bimini 306 2008 vs Grady-White Marlin 300 2009 — Same Brand, Different Boat

The Grady-White Bimini 306 2008 vs Grady-White Marlin 300 2009 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Grady-White Marlin 300 2009 measures 32,6 feet overall (2009), giving it roughly 29,6 additional feet of deck space compared to the Grady-White Bimini 306 2008 at 3,0 feet (2008). Weight tells a clearer story for trailering families: the Grady-White Marlin 300 2009 tips the scales at 8 221 lbs — 8 156 lbs less than the Grady-White Bimini 306 2008 at 65 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling — 700 hp for the Grady-White Bimini 306 2008 and 700 hp for the Grady-White Marlin 300 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Grady-White Bimini 306 2008 carries 29 gallons versus 3 gallons in the Grady-White Marlin 300 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Grady-White Marlin 300 2009 at 32,6 ft is the right call if deck space, comfort, and entertaining are top of your list. The Grady-White Bimini 306 2008 at 3,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Grady-White Bimini 306 2008 vs Grady-White Marlin 300 2009 — Common Questions

Which is the larger boat — the Grady-White Bimini 306 2008 or the Grady-White Marlin 300 2009?
The Grady-White Marlin 300 2009 is the longer of the two at 32,6 feet overall. The Grady-White Bimini 306 2008 comes in at 3,0 feet, making it roughly 29,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Grady-White Bimini 306 2008 or the Grady-White Marlin 300 2009?
For trailering, the Grady-White Bimini 306 2008 has the edge at 65 lbs dry weight versus 8 221 lbs for the Grady-White Marlin 300 2009. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Grady-White Bimini 306 2008 is Coast Guard rated for 9 passengers, while the Grady-White Marlin 300 2009 is certified for 9. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Grady-White Bimini 306 2008 and Grady-White Marlin 300 2009 share an 10 ft. 7 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Grady-White Bimini 306 2008 or the Grady-White Marlin 300 2009?
The Grady-White Bimini 306 2008 has the bigger tank at 29 gallons, versus 3 gallons on the Grady-White Marlin 300 2009. That 26-gallon difference translates to roughly 78–130 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Grady-White Bimini 306 2008 and Grady-White Marlin 300 2009 from the same manufacturer?
Yes — both the Grady-White Bimini 306 2008 and the Grady-White Marlin 300 2009 are built by Grady-White. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
