Crestliner Backwater 1860 Tiller 2011 vs Crestliner LSi 2085 2006 — Same Brand, Different Boat

The Crestliner Backwater 1860 Tiller 2011 vs Crestliner LSi 2085 2006 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 16,4 additional feet of deck space compared to the Crestliner LSi 2085 2006 at 2,0 feet (2006). At 83 lbs and 2 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 115 hp, the Crestliner LSi 2085 2006 has a 40-hp advantage over the Crestliner Backwater 1860 Tiller 2011's 75-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 LSi 2085 2006 is rated for 12 passengers, while the Crestliner Backwater 1860 Tiller 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner LSi 2085 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner LSi 2085 2006 comes in at 0 lbs per hp versus 1 lbs per hp for the Crestliner Backwater 1860 Tiller 2011. 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.

The Crestliner LSi 2085 2006 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Crestliner Backwater 1860 Tiller 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.

Bottom line: Choose the Crestliner LSi 2085 2006 if your priority is putting more people on the water — it handles 12 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Crestliner Backwater 1860 Tiller 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

Crestliner Backwater 1860 Tiller 2011 vs Crestliner LSi 2085 2006 — Common Questions

Which is the larger boat — the Crestliner Backwater 1860 Tiller 2011 or the Crestliner LSi 2085 2006?
The Crestliner Backwater 1860 Tiller 2011 is the longer of the two at 18,4 feet overall. The Crestliner LSi 2085 2006 comes in at 2,0 feet, making it roughly 16,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner Backwater 1860 Tiller 2011 or the Crestliner LSi 2085 2006?
For trailering, the Crestliner LSi 2085 2006 has the edge at 2 lbs dry weight versus 83 lbs for the Crestliner Backwater 1860 Tiller 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Crestliner LSi 2085 2006 is rated to a maximum of 115 hp, giving it the larger power ceiling. The Crestliner Backwater 1860 Tiller 2011 tops out at 75 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Crestliner Backwater 1860 Tiller 2011 is Coast Guard rated for 4 passengers, while the Crestliner LSi 2085 2006 is certified for 12. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Crestliner LSi 2085 2006 measures 102" wide, compared to 86" for the Crestliner Backwater 1860 Tiller 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Crestliner Backwater 1860 Tiller 2011 and Crestliner LSi 2085 2006 from the same manufacturer?
Yes — both the Crestliner Backwater 1860 Tiller 2011 and the Crestliner LSi 2085 2006 are built by Crestliner. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
