When two boats share the same hull type — in this case both the Crestliner Fish Hawk 1750 SC 2011 and the Crestliner Super Hawk 1800 I/O 2008 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 1750 SC 2011 at 17,5 ft versus Crestliner Super Hawk 1800 I/O 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Super Hawk 1800 I/O 2008 tips the scales at 2 105 lbs — 2 094 lbs less than the Crestliner Fish Hawk 1750 SC 2011 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 220 hp, the Crestliner Super Hawk 1800 I/O 2008 has a 95-hp advantage over the Crestliner Fish Hawk 1750 SC 2011's 125-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 Super Hawk 1800 I/O 2008 carries 33 gallons versus 24 gallons in the Crestliner Fish Hawk 1750 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 Super Hawk 1800 I/O 2008 is rated for 7 passengers, while the Crestliner Fish Hawk 1750 SC 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Super Hawk 1800 I/O 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Fish Hawk 1750 SC 2011 comes in at 0 lbs per hp versus 10 lbs per hp for the Crestliner Super Hawk 1800 I/O 2008. 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 Super Hawk 1800 I/O 2008 if your priority is putting more people on the water — it handles 7 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Crestliner Fish Hawk 1750 SC 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
