When two boats share the same hull type — in this case both the Crestliner Fish Hawk 1700 SC 2010 and the Crestliner Fish Hawk Series 1850 SC 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 Fish Hawk 1700 SC 2010 at 17,2 ft versus Crestliner Fish Hawk Series 1850 SC 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Fish Hawk Series 1850 SC 2009 tips the scales at 125 lbs — 114 lbs less than the Crestliner Fish Hawk 1700 SC 2010 at 11 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.
The power gap is worth calling out. Rated to 150 hp, the Crestliner Fish Hawk Series 1850 SC 2009 has a 35-hp advantage over the Crestliner Fish Hawk 1700 SC 2010's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Crestliner Fish Hawk Series 1850 SC 2009 carries 31 gallons versus 3 gallons in the Crestliner Fish Hawk 1700 SC 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 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.
At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Fish Hawk 1700 SC 2010 comes in at 0 lbs per hp versus 1 lbs per hp for the Crestliner Fish Hawk Series 1850 SC 2009. 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: Performance buyers should lean toward the Crestliner Fish Hawk Series 1850 SC 2009 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Crestliner Fish Hawk 1700 SC 2010 with its 115-hp rating is the more economical daily driver.
