Crestliner Backwater 1860 SC 2011 vs Crestliner CMV 1750 2006: Same Brand, Different Boat

The Crestliner Backwater 1860 SC 2011 vs Crestliner CMV 1750 2006 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.

On paper these two are close siblings in the size department - Crestliner Backwater 1860 SC 2011 at 18,4 ft versus Crestliner CMV 1750 2006 at 17,0 ft. Weight tells a clearer story for trailering families: the Crestliner CMV 1750 2006 tips the scales at 1 100 lbs - 220 lbs less than the Crestliner Backwater 1860 SC 2011 at 880 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.

Both boats share a closely matched power ceiling - 115 hp for the Crestliner Backwater 1860 SC 2011 and 125 hp for the Crestliner CMV 1750 2006. 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 Crestliner CMV 1750 2006 carries 24 gallons versus 20 gallons in the Crestliner Backwater 1860 SC 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 4 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: The Crestliner Backwater 1860 SC 2011 and Crestliner CMV 1750 2006 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Crestliner Backwater 1860 SC 2011 vs Crestliner CMV 1750 2006 - Common Questions

Which is the larger boat - the Crestliner Backwater 1860 SC 2011 or the Crestliner CMV 1750 2006?
The Crestliner Backwater 1860 SC 2011 is the longer of the two at 18,4 feet overall. The Crestliner CMV 1750 2006 comes in at 17,0 feet, making it roughly 1,4 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Crestliner Backwater 1860 SC 2011 or the Crestliner CMV 1750 2006?
For trailering, the Crestliner Backwater 1860 SC 2011 has the edge at 880 lbs dry weight versus 1 100 lbs for the Crestliner CMV 1750 2006. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Crestliner CMV 1750 2006 is rated to a maximum of 125 hp, giving it the larger power ceiling. The Crestliner Backwater 1860 SC 2011 tops out at 115 hp. Keep in mind that maximum ratings are just that - matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Crestliner Backwater 1860 SC 2011 is Coast Guard rated for 4 passengers, while the Crestliner CMV 1750 2006 is certified for 4. Note that legal capacity and comfortable capacity aren't always the same thing - on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Crestliner CMV 1750 2006 measures 91" wide, compared to 86" for the Crestliner Backwater 1860 SC 2011. The US standard-width towing limit is 8’6" (102") in most states - anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank - the Crestliner Backwater 1860 SC 2011 or the Crestliner CMV 1750 2006?
The Crestliner CMV 1750 2006 has the bigger tank at 24 gallons, versus 20 gallons on the Crestliner Backwater 1860 SC 2011. That 4-gallon difference translates to roughly 12–20 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Crestliner Backwater 1860 SC 2011 and Crestliner CMV 1750 2006 from the same manufacturer?
Yes - both the Crestliner Backwater 1860 SC 2011 and the Crestliner CMV 1750 2006 are built by Crestliner. 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.
