Grady-White Marlin 300 2010 vs Grady-White Marlin 300 2012 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the Grady-White Marlin 300 2010 and the Grady-White Marlin 300 2012 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Grady-White Marlin 300 2010 at 32,6 ft versus Grady-White Marlin 300 2012 at 32,6 ft. At 8 221 lbs and 8 221 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 700 hp for the Grady-White Marlin 300 2010 and 700 hp for the Grady-White Marlin 300 2012. 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. Both carry nearly identical fuel loads — 3 gal and 3 gal — so range won't be a tiebreaker here.

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 2010 and Grady-White Marlin 300 2012 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Grady-White Marlin 300 2010 vs Grady-White Marlin 300 2012 — Common Questions

Which is the larger boat — the Grady-White Marlin 300 2010 or the Grady-White Marlin 300 2012?
The Grady-White Marlin 300 2012 is the longer of the two at 32,6 feet overall. The Grady-White Marlin 300 2010 comes in at 32,6 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Grady-White Marlin 300 2010 or the Grady-White Marlin 300 2012?
For trailering, the Grady-White Marlin 300 2012 has the edge at 8 221 lbs dry weight versus 8 221 lbs for the Grady-White Marlin 300 2010. 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 Marlin 300 2010 is Coast Guard rated for 9 passengers, while the Grady-White Marlin 300 2012 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 Marlin 300 2010 and Grady-White Marlin 300 2012 share an 10 ft. 7 in. (3.23 m) 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.
How do the fuel tanks compare on the Grady-White Marlin 300 2010 and Grady-White Marlin 300 2012?
Both boats carry similar fuel loads — 3 gallons and 3 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Grady-White Marlin 300 2010 and Grady-White Marlin 300 2012 from the same manufacturer?
Yes — both the Grady-White Marlin 300 2010 and the Grady-White Marlin 300 2012 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.
