Both the Mariah R23 2012 and the Mariah SC25 Cuddy Cabin 2008 are modified-V designs, the first built in aluminium and the second in fibreglass, so 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 R23 2012 at 23,4 ft versus Mariah SC25 Cuddy Cabin 2008 at 25,0 ft. Weight tells a clearer story for trailering families: the Mariah SC25 Cuddy Cabin 2008 tips the scales at 4 250 lbs - 250 lbs less than the Mariah R23 2012 at 4 000 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.
The power gap is worth calling out. Rated to 425 hp, the Mariah SC25 Cuddy Cabin 2008 has a 105-hp advantage over the Mariah R23 2012's 320-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Mariah SC25 Cuddy Cabin 2008 carries 90 gallons versus 52 gallons in the Mariah R23 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
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: Performance buyers should lean toward the Mariah SC25 Cuddy Cabin 2008 and its 425-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Mariah R23 2012 with its 320-hp rating is the more economical daily driver.
