When two boats share the same hull type — in this case both the Crestliner CXJ Series 2070 CC 2009 and the Crestliner SS Series (1657 SS) 2012 are modified vee designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Crestliner SS Series (1657 SS) 2012 measures 16,0 feet overall (2012), giving it roughly 14,0 additional feet of deck space compared to the Crestliner CXJ Series 2070 CC 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Crestliner CXJ Series 2070 CC 2009 tips the scales at 139 lbs — 130 lbs more than the Crestliner SS Series (1657 SS) 2012 at 9 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.
The power gap is worth calling out. Rated to 115 hp, the Crestliner CXJ Series 2070 CC 2009 has a 65-hp advantage over the Crestliner SS Series (1657 SS) 2012's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Crestliner CXJ Series 2070 CC 2009 carries 21 gallons versus 12 gallons in the Crestliner SS Series (1657 SS) 2012. 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 CXJ Series 2070 CC 2009 is rated for 7 passengers, while the Crestliner SS Series (1657 SS) 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner CXJ Series 2070 CC 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner SS Series (1657 SS) 2012 comes in at 0 lbs per hp versus 1 lbs per hp for the Crestliner CXJ Series 2070 CC 2009. 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 CXJ Series 2070 CC 2009 if your priority is putting more people on the water — it handles 7 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Crestliner SS Series (1657 SS) 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
