Mariah G23 2010 vs Mariah SX25 2010 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the Mariah G23 2010 and the Mariah SX25 2010 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 — Mariah G23 2010 at 23,0 ft versus Mariah SX25 2010 at 25,2 ft. At 45 lbs and 46 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.

The power gap is worth calling out. Rated to 425 hp, the Mariah SX25 2010 has a 105-hp advantage over the Mariah G23 2010's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 57 gal and 57 gal — so range won't be a tiebreaker here.

Both boats are rated for 12 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 Mariah SX25 2010 at 25,2 ft is the right call if deck space, comfort, and entertaining are top of your list. The Mariah G23 2010 at 23,0 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.

Mariah G23 2010 vs Mariah SX25 2010 — Common Questions

Which is the larger boat — the Mariah G23 2010 or the Mariah SX25 2010?
The Mariah SX25 2010 is the longer of the two at 25,2 feet overall. The Mariah G23 2010 comes in at 23,0 feet, making it roughly 2,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Mariah G23 2010 or the Mariah SX25 2010?
For trailering, the Mariah G23 2010 has the edge at 45 lbs dry weight versus 46 lbs for the Mariah SX25 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.
Which boat can handle a bigger outboard?
The Mariah SX25 2010 is rated to a maximum of 425 hp, giving it the larger power ceiling. The Mariah G23 2010 tops out at 320 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Mariah G23 2010 is Coast Guard rated for 12 passengers, while the Mariah SX25 2010 is certified for 12. 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 Mariah G23 2010 and Mariah SX25 2010 share an 8 ft. 6 in. (2.6 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 Mariah G23 2010 and Mariah SX25 2010?
Both boats carry similar fuel loads — 57 gallons and 57 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Mariah G23 2010 and Mariah SX25 2010 from the same manufacturer?
Yes — both the Mariah G23 2010 and the Mariah SX25 2010 are built by Mariah. 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.
