The Crestliner Fish Hawk 1650 SC 2012 is a deep-V design and the Crestliner Sport Angler Series 1650 2009 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 Sport Angler Series 1650 2009 at 16,0 ft. At 1 060 lbs and 1 000 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.
The power gap is worth calling out. Rated to 115 hp, the Crestliner Sport Angler Series 1650 2009 has a 25-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. Both carry nearly identical fuel loads - 20 gal and 17 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Crestliner Fish Hawk 1650 SC 2012 is rated for 6 passengers, while the Crestliner Sport Angler Series 1650 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Fish Hawk 1650 SC 2012 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Sport Angler Series 1650 2009 comes in at 9 lbs per hp versus 12 lbs per hp for the Crestliner Fish Hawk 1650 SC 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 Fish Hawk 1650 SC 2012 if your priority is putting more people on the water - it handles 6 passengers and at 16,7 ft it has the deck room to back that rating up comfortably. The Crestliner Sport Angler Series 1650 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
