The Crestliner Fish Hawk 1600 SC 2012 is a deep-V design and the Crestliner Retriever Jon 2070 2013 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 Retriever Jon 2070 2013 measures 20,0 feet overall (2013), giving it roughly 4,0 additional feet of deck space compared to the Crestliner Fish Hawk 1600 SC 2012 at 16,0 feet (2012). Weight tells a clearer story for trailering families: the Crestliner Fish Hawk 1600 SC 2012 tips the scales at 830 lbs - 120 lbs more than the Crestliner Retriever Jon 2070 2013 at 710 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.
Both boats share a closely matched power ceiling - 60 hp for the Crestliner Fish Hawk 1600 SC 2012 and 75 hp for the Crestliner Retriever Jon 2070 2013. 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.
For family outings this is probably the sharpest distinction between the two. The Crestliner Retriever Jon 2070 2013 is rated for 7 passengers, while the Crestliner Fish Hawk 1600 SC 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Retriever Jon 2070 2013 could be the deciding factor.
Bottom line: Choose the Crestliner Retriever Jon 2070 2013 if your priority is putting more people on the water - it handles 7 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Crestliner Fish Hawk 1600 SC 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
