When two boats share the same hull type — in this case both the Mariah R23 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 R23 2012 at 23,4 ft versus Mariah SC23 Cuddy Cabin 2008 at 23,0 ft. At 4 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 — 320 hp for the Mariah R23 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 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 R23 2012 and its 320-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Mariah SC23 Cuddy Cabin 2008 with its 300-hp rating is the more economical daily driver.
