When two boats share the same hull type — in this case both the Crestliner Backwater 1860 SC 2011 and the Crestliner Jons - CR 1448M 2009 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 Backwater 1860 SC 2011 measures 18,4 feet overall (2011), giving it roughly 4,4 additional feet of deck space compared to the Crestliner Jons - CR 1448M 2009 at 14,0 feet (2009). Weight tells a clearer story for trailering families: the Crestliner Jons - CR 1448M 2009 tips the scales at 365 lbs — 277 lbs less than the Crestliner Backwater 1860 SC 2011 at 88 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 Backwater 1860 SC 2011 has a 90-hp advantage over the Crestliner Jons - CR 1448M 2009's 25-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 4 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Crestliner Backwater 1860 SC 2011 at 18,4 ft is the right call if deck space, comfort, and entertaining are top of your list. The Crestliner Jons - CR 1448M 2009 at 14,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
