The Crestliner Kodiak 16 SC 2012 is a deep-V design and the Crestliner Sportsman 16 2006 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 16 SC 2012 at 16,5 ft versus Crestliner Sportsman 16 2006 at 16,0 ft. Weight tells a clearer story for trailering families: the Crestliner Kodiak 16 SC 2012 tips the scales at 704 lbs - 274 lbs more than the Crestliner Sportsman 16 2006 at 430 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 Kodiak 16 SC 2012 and 40 hp for the Crestliner Sportsman 16 2006. 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 Sportsman 16 2006 is rated for 6 passengers, while the Crestliner Kodiak 16 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 Sportsman 16 2006 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Sportsman 16 2006 comes in at 11 lbs per hp versus 12 lbs per hp for the Crestliner Kodiak 16 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 Sportsman 16 2006 if your priority is putting more people on the water - it handles 6 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Crestliner Kodiak 16 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.
