Matching a modified vee Crestliner CXJ 1870 SC 2008 against a deep vee Crestliner Pro Tiller 1850 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 Pro Tiller 1850 2013 at 18,7 ft. Weight tells a clearer story for trailering families: the Crestliner CXJ 1870 SC 2008 tips the scales at 1 175 lbs — 1 161 lbs more than the Crestliner Pro Tiller 1850 2013 at 14 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 90 hp for the Crestliner Pro Tiller 1850 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 Pro Tiller 1850 2013 carries 37 gallons versus 21 gallons in the Crestliner CXJ 1870 SC 2008. 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 Pro Tiller 1850 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 Pro Tiller 1850 2013 could be the deciding factor.
Bottom line: Choose the Crestliner Pro Tiller 1850 2013 if your priority is putting more people on the water — it handles 6 passengers and at 18,7 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.
