When two boats share the same hull type — in this case both the Crestliner Backwater 1760 SC 2011 and the Crestliner Fish Hawk Series 1850 Tiller 2009 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 — Crestliner Backwater 1760 SC 2011 at 17,3 ft versus Crestliner Fish Hawk Series 1850 Tiller 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Backwater 1760 SC 2011 tips the scales at 789 lbs — 664 lbs more than the Crestliner Fish Hawk Series 1850 Tiller 2009 at 125 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 — 75 hp for the Crestliner Backwater 1760 SC 2011 and 90 hp for the Crestliner Fish Hawk Series 1850 Tiller 2009. 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 Fish Hawk Series 1850 Tiller 2009 carries 31 gallons versus 2 gallons in the Crestliner Backwater 1760 SC 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 Crestliner Fish Hawk Series 1850 Tiller 2009 is rated for 6 passengers, while the Crestliner Backwater 1760 SC 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Fish Hawk Series 1850 Tiller 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Fish Hawk Series 1850 Tiller 2009 comes in at 1 lbs per hp versus 11 lbs per hp for the Crestliner Backwater 1760 SC 2011. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Crestliner Fish Hawk Series 1850 Tiller 2009 if your priority is putting more people on the water — it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Crestliner Backwater 1760 SC 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
