Crestliner Backwater 1870 SC/CC 2010 vs Crestliner Sun Cast 2185 Angler 2009 — Same Brand, Different Boat

Matching a modified vee Crestliner Backwater 1870 SC/CC 2010 against a pontoon Crestliner Sun Cast 2185 Angler 2009 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.

Size is the most obvious dividing line here. The Crestliner Backwater 1870 SC/CC 2010 measures 18,0 feet overall (2010), giving it roughly 16,0 additional feet of deck space compared to the Crestliner Sun Cast 2185 Angler 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Crestliner Backwater 1870 SC/CC 2010 tips the scales at 1 175 lbs — 1 156 lbs more than the Crestliner Sun Cast 2185 Angler 2009 at 19 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 90 hp, the Crestliner Backwater 1870 SC/CC 2010 has a 30-hp advantage over the Crestliner Sun Cast 2185 Angler 2009's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Crestliner Sun Cast 2185 Angler 2009 is rated for 9 passengers, while the Crestliner Backwater 1870 SC/CC 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Sun Cast 2185 Angler 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Sun Cast 2185 Angler 2009 comes in at 0 lbs per hp versus 13 lbs per hp for the Crestliner Backwater 1870 SC/CC 2010. 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 Sun Cast 2185 Angler 2009 if your priority is putting more people on the water — it handles 9 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Crestliner Backwater 1870 SC/CC 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Crestliner Backwater 1870 SC/CC 2010 vs Crestliner Sun Cast 2185 Angler 2009 — Common Questions

The Crestliner Backwater 1870 SC/CC 2010 is the longer of the two at 18,0 feet overall. The Crestliner Sun Cast 2185 Angler 2009 comes in at 2,0 feet, making it roughly 16,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner Backwater 1870 SC/CC 2010 or the Crestliner Sun Cast 2185 Angler 2009?
For trailering, the Crestliner Sun Cast 2185 Angler 2009 has the edge at 19 lbs dry weight versus 1 175 lbs for the Crestliner Backwater 1870 SC/CC 2010.

Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Crestliner Backwater 1870 SC/CC 2010 is rated to a maximum of 90 hp, giving it the larger power ceiling. The Crestliner Sun Cast 2185 Angler 2009 tops out at 60 hp.

How many people can each boat hold?
The Crestliner Backwater 1870 SC/CC 2010 is Coast Guard rated for 5 passengers, while the Crestliner Sun Cast 2185 Angler 2009 is certified for 9.

Which boat has the better power-to-weight ratio?
The Crestliner Sun Cast 2185 Angler 2009 has a better power-to-weight ratio at 0 lbs per hp compared to 13 lbs per hp for the Crestliner Backwater 1870 SC/CC 2010.
