The Crestliner Kodiak 18 Tiller 2013 is a deep-V design and the Crestliner Super Hawk 1900 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 Kodiak 18 Tiller 2013 at 18,0 ft versus Crestliner Super Hawk 1900 2011 at 19,6 ft. Weight tells a clearer story for trailering families: the Crestliner Super Hawk 1900 2011 tips the scales at 1 630 lbs - 720 lbs less than the Crestliner Kodiak 18 Tiller 2013 at 910 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 Super Hawk 1900 2011 has a 130-hp advantage over the Crestliner Kodiak 18 Tiller 2013's 70-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 1900 2011 carries 40 gallons versus 17 gallons in the Crestliner Kodiak 18 Tiller 2013. 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 1900 2011 is rated for 8 passengers, while the Crestliner Kodiak 18 Tiller 2013 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 1900 2011 could be the deciding factor.
Bottom line: Choose the Crestliner Super Hawk 1900 2011 if your priority is putting more people on the water - it handles 8 passengers and at 19,6 ft it has the deck room to back that rating up comfortably. The Crestliner Kodiak 18 Tiller 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
