When two boats share the same hull type — in this case both the Crestliner Canadian 1650 2010 and the Crestliner Fish Hawk Series 1850 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 1650 2010 at 16,3 ft versus Crestliner Fish Hawk Series 1850 WT 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Fish Hawk Series 1850 WT 2009 tips the scales at 125 lbs — 124 lbs less than the Crestliner Canadian 1650 2010 at 1 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 WT 2009 has a 35-hp advantage over the Crestliner Canadian 1650 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 WT 2009 carries 31 gallons versus 2 gallons in the Crestliner Canadian 1650 2010. 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 WT 2009 is rated for 6 passengers, while the Crestliner Canadian 1650 2010 caps at 5. 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 WT 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Canadian 1650 2010 comes in at 0 lbs per hp versus 1 lbs per hp for the Crestliner Fish Hawk Series 1850 WT 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 Fish Hawk Series 1850 WT 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 Canadian 1650 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
