Mariah R20 2012 vs Mariah Shabah 183/Z183 2000 — Same Brand, Different Boat
The Mariah R20 2012 vs Mariah Shabah 183/Z183 2000 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Engine data for the Mariah Shabah 183/Z183 2000 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Mariah Shabah 183/Z183 2000 carries 38 gallons versus 22 gallons in the Mariah R20 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 Shabah 183/Z183 2000 is rated for 6 passengers, while the Mariah R20 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 Shabah 183/Z183 2000 could be the deciding factor.
