The Crestliner Fish Hawk 1650 DC 2012 is a deep-V design and the Crestliner Sportfish 1950 SST 2011 is a modified-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.
Size is the most obvious dividing line here. The Crestliner Sportfish 1950 SST 2011 measures 20,6 feet overall (2011), giving it roughly 3,9 additional feet of deck space compared to the Crestliner Fish Hawk 1650 DC 2012 at 16,7 feet (2012). Weight tells a clearer story for trailering families: the Crestliner Sportfish 1950 SST 2011 tips the scales at 1 850 lbs - 790 lbs less than the Crestliner Fish Hawk 1650 DC 2012 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 200 hp, the Crestliner Sportfish 1950 SST 2011 has a 110-hp advantage over the Crestliner Fish Hawk 1650 DC 2012's 90-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 Sportfish 1950 SST 2011 carries 40 gallons versus 20 gallons in the Crestliner Fish Hawk 1650 DC 2012. 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 Sportfish 1950 SST 2011 is rated for 8 passengers, while the Crestliner Fish Hawk 1650 DC 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Sportfish 1950 SST 2011 could be the deciding factor.
Bottom line: Choose the Crestliner Sportfish 1950 SST 2011 if your priority is putting more people on the water - it handles 8 passengers and at 20,6 ft it has the deck room to back that rating up comfortably. The Crestliner Fish Hawk 1650 DC 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
