The Mariah Shabah 182/Z182 2001 has the bigger tank at 38 gallons, versus 22 gallons on the Mariah R18 2011. That 16-gallon difference translates to roughly 48–80 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Detailed Evaluation & Buyer Recommendation

Mariah R18 2011 vs Mariah Shabah 182/Z182 2001 — Same Brand, Different Boat

The Mariah R18 2011 vs Mariah Shabah 182/Z182 2001 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.

The Mariah R18 2011 carries a rated maximum of 225 hp. Engine data for the Mariah Shabah 182/Z182 2001 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 182/Z182 2001 carries 38 gallons versus 22 gallons in the Mariah R18 2011. 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 182/Z182 2001 is rated for 9 passengers, while the Mariah R18 2011 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mariah Shabah 182/Z182 2001 could be the deciding factor.

Bottom line: Choose the Mariah Shabah 182/Z182 2001 if your priority is putting more people on the water — it handles 9 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Mariah R18 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
