Matching a modified vee Crestliner CXJ 1870 SC 2008 against a deep vee Crestliner Kodiak 18 Tiller 2013 means you're likely deciding between two genuinely 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 CXJ 1870 SC 2008 at 18,0 ft versus Crestliner Kodiak 18 Tiller 2013 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner CXJ 1870 SC 2008 tips the scales at 1 175 lbs — 1 084 lbs more than the Crestliner Kodiak 18 Tiller 2013 at 91 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 — 90 hp for the Crestliner CXJ 1870 SC 2008 and 70 hp for the Crestliner Kodiak 18 Tiller 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. Fuel capacity breaks the other way: the Crestliner CXJ 1870 SC 2008 carries 21 gallons versus 17 gallons in the Crestliner Kodiak 18 Tiller 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Crestliner Kodiak 18 Tiller 2013 is rated for 6 passengers, while the Crestliner CXJ 1870 SC 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Kodiak 18 Tiller 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Kodiak 18 Tiller 2013 comes in at 1 lbs per hp versus 13 lbs per hp for the Crestliner CXJ 1870 SC 2008. 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 Kodiak 18 Tiller 2013 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 CXJ 1870 SC 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
