The Crestliner Fish Hawk 1650 SC 2012 is a deep-V design and the Crestliner Super Hawk 1800 I/O 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.

On paper these two are close siblings in the size department - Crestliner Fish Hawk 1650 SC 2012 at 16,7 ft versus Crestliner Super Hawk 1800 I/O 2011 at 18,2 ft. Weight tells a clearer story for trailering families: the Crestliner Super Hawk 1800 I/O 2011 tips the scales at 2 105 lbs - 1 045 lbs less than the Crestliner Fish Hawk 1650 SC 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 220 hp, the Crestliner Super Hawk 1800 I/O 2011 has a 130-hp advantage over the Crestliner Fish Hawk 1650 SC 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 Super Hawk 1800 I/O 2011 carries 33 gallons versus 20 gallons in the Crestliner Fish Hawk 1650 SC 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 Super Hawk 1800 I/O 2011 is rated for 7 passengers, while the Crestliner Fish Hawk 1650 SC 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 Super Hawk 1800 I/O 2011 could be the deciding factor.
