The Crestliner Jons - CR 1852MT 2009 comes in at 11 lbs per hp versus 14 lbs per hp for the Crestliner Fish Hawk 1600 Tiller 2012. The lower the ratio the more explosive the acceleration - meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Crestliner Jons - CR 1852MT 2009 if your priority is putting more people on the water - it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Crestliner Fish Hawk 1600 Tiller 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.
