When two boats share the same hull type — in this case both the Crestliner Canadian Series 1850 2009 and the Crestliner Fish Hawk Series 1750 WT 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 Canadian Series 1850 2009 at 18,0 ft versus Crestliner Fish Hawk Series 1750 WT 2009 at 17,0 ft. At 15 lbs and 11 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 175 hp, the Crestliner Canadian Series 1850 2009 has a 50-hp advantage over the Crestliner Fish Hawk Series 1750 WT 2009'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 Canadian Series 1850 2009 carries 39 gallons versus 24 gallons in the Crestliner Fish Hawk Series 1750 WT 2009. 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 Canadian Series 1850 2009 is rated for 7 passengers, while the Crestliner Fish Hawk Series 1750 WT 2009 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Canadian Series 1850 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Fish Hawk Series 1750 WT 2009 comes in at 0 lbs per hp versus 0 lbs per hp for the Crestliner Canadian Series 1850 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: Choose the Crestliner Canadian Series 1850 2009 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 Series 1750 WT 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
