The Crestliner Backwater 1860 Tiller 2011 vs Crestliner CR 1648 TS 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Crestliner Backwater 1860 Tiller 2011 measures 18,4 feet overall (2011), giving it roughly 3,4 additional feet of deck space compared to the Crestliner CR 1648 TS 2005 at 15,0 feet (2005). Weight tells a clearer story for trailering families: the Crestliner CR 1648 TS 2005 tips the scales at 275 lbs — 192 lbs less than the Crestliner Backwater 1860 Tiller 2011 at 83 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 75 hp, the Crestliner Backwater 1860 Tiller 2011 has a 40-hp advantage over the Crestliner CR 1648 TS 2005's 35-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 Tiller 2011 at 18,4 ft is the right call if deck space, comfort, and entertaining are top of your list. The Crestliner CR 1648 TS 2005 at 15,0 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.
