The Crestliner CX Bass Series 19 2009 is a modified-V design and the Crestliner Fish Hawk 1650 WT 2013 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Crestliner CX Bass Series 19 2009 at 18,0 ft versus Crestliner Fish Hawk 1650 WT 2013 at 16,7 ft. Weight tells a clearer story for trailering families: the Crestliner CX Bass Series 19 2009 tips the scales at 1 250 lbs - 190 lbs more than the Crestliner Fish Hawk 1650 WT 2013 at 1 060 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 135 hp, the Crestliner CX Bass Series 19 2009 has a 45-hp advantage over the Crestliner Fish Hawk 1650 WT 2013's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 22 gal and 20 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Crestliner Fish Hawk 1650 WT 2013 is rated for 6 passengers, while the Crestliner CX Bass Series 19 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Fish Hawk 1650 WT 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner CX Bass Series 19 2009 comes in at 9 lbs per hp versus 12 lbs per hp for the Crestliner Fish Hawk 1650 WT 2013. 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 1650 WT 2013 if your priority is putting more people on the water - it handles 6 passengers and at 16,7 ft it has the deck room to back that rating up comfortably. The Crestliner CX Bass Series 19 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
