Both the Crestliner Fish Hawk 1750 SC 2011 and the Crestliner Retriever 2070 CC 2012 are modified-V designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department - Crestliner Fish Hawk 1750 SC 2011 at 17,5 ft versus Crestliner Retriever 2070 CC 2012 at 20,0 ft. At 1 100 lbs and 1 170 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling - 125 hp for the Crestliner Fish Hawk 1750 SC 2011 and 115 hp for the Crestliner Retriever 2070 CC 2012. 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.
Both boats are rated for 6 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Crestliner Retriever 2070 CC 2012 at 20,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Crestliner Fish Hawk 1750 SC 2011 at 17,5 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
