Both the Crestliner Canadian 1650 2010 and the Crestliner Fish Hawk Series 1700 SC 2009 are modified-V designs, both built in aluminium, so 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 1700 SC 2009 at 17,0 ft. At 1 000 lbs and 1 100 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.
Both boats share a closely matched power ceiling - 115 hp for the Crestliner Canadian 1650 2010 and 115 hp for the Crestliner Fish Hawk Series 1700 SC 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 1700 SC 2009 carries 30 gallons versus 20 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 1700 SC 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 1700 SC 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 9 lbs per hp versus 10 lbs per hp for the Crestliner Fish Hawk Series 1700 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: Choose the Crestliner Fish Hawk Series 1700 SC 2009 if your priority is putting more people on the water - it handles 6 passengers and at 17,0 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.
