Mariah G21 2012 vs Mariah SC23 Cuddy Cabin 2008 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the Mariah G21 2012 and the Mariah SC23 Cuddy Cabin 2008 are modified vee designs with aluminum 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 G21 2012 at 21,4 ft versus Mariah SC23 Cuddy Cabin 2008 at 23,0 ft. At 36 lbs and 36 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 — 300 hp for the Mariah G21 2012 and 300 hp for the Mariah SC23 Cuddy Cabin 2008. 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 Mariah SC23 Cuddy Cabin 2008 carries 57 gallons versus 35 gallons in the Mariah G21 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Mariah SC23 Cuddy Cabin 2008 is rated for 12 passengers, while the Mariah G21 2012 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mariah SC23 Cuddy Cabin 2008 could be the deciding factor.

Bottom line: Choose the Mariah SC23 Cuddy Cabin 2008 if your priority is putting more people on the water — it handles 12 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Mariah G21 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.

Mariah G21 2012 vs Mariah SC23 Cuddy Cabin 2008 — Common Questions

Which is the larger boat — the Mariah G21 2012 or the Mariah SC23 Cuddy Cabin 2008?
The Mariah SC23 Cuddy Cabin 2008 is the longer of the two at 23,0 feet overall. The Mariah G21 2012 comes in at 21,4 feet, making it roughly 1,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Mariah G21 2012 or the Mariah SC23 Cuddy Cabin 2008?
For trailering, the Mariah SC23 Cuddy Cabin 2008 has the edge at 36 lbs dry weight versus 36 lbs for the Mariah G21 2012.

How many people can each boat hold?
The Mariah G21 2012 is Coast Guard rated for 1 passengers, while the Mariah SC23 Cuddy Cabin 2008 is certified for 12.

Do these boats require an oversize trailer permit to tow on US highways?
Both the Mariah G21 2012 and Mariah SC23 Cuddy Cabin 2008 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.
Which boat has the larger fuel tank — the Mariah G21 2012 or the Mariah SC23 Cuddy Cabin 2008?

Yes — both the Mariah G21 2012 and the Mariah SC23 Cuddy Cabin 2008 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.
