Crestliner LSi 2085 2006 vs Crestliner Mirage 1800 2006 — Same Brand, Different Boat

The Crestliner LSi 2085 2006 vs Crestliner Mirage 1800 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 Mirage 1800 2006 measures 18,0 feet overall (2006), giving it roughly 16,0 additional feet of deck space compared to the Crestliner LSi 2085 2006 at 2,0 feet (2006). Weight tells a clearer story for trailering families: the Crestliner Mirage 1800 2006 tips the scales at 147 lbs — 145 lbs less than the Crestliner LSi 2085 2006 at 2 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 175 hp, the Crestliner Mirage 1800 2006 has a 60-hp advantage over the Crestliner LSi 2085 2006's 115-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 Mirage 1800 2006 carries 39 gallons versus 25 gallons in the Crestliner LSi 2085 2006. 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 LSi 2085 2006 is rated for 12 passengers, while the Crestliner Mirage 1800 2006 caps at 7. 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 Mirage 1800 2006. 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 Mirage 1800 2006 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 Mirage 1800 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

Crestliner LSi 2085 2006 vs Crestliner Mirage 1800 2006 — Common Questions

Which is the larger boat — the Crestliner LSi 2085 2006 or the Crestliner Mirage 1800 2006?
The Crestliner Mirage 1800 2006 is the longer of the two at 18,0 feet overall. The Crestliner LSi 2085 2006 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 LSi 2085 2006 or the Crestliner Mirage 1800 2006?
For trailering, the Crestliner LSi 2085 2006 has the edge at 2 lbs dry weight versus 147 lbs for the Crestliner Mirage 1800 2006. 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 Mirage 1800 2006 is rated to a maximum of 175 hp, giving it the larger power ceiling. The Crestliner LSi 2085 2006 tops out at 115 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 LSi 2085 2006 is Coast Guard rated for 12 passengers, while the Crestliner Mirage 1800 2006 is certified for 7. 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 has the better power-to-weight ratio?
The Crestliner LSi 2085 2006 has a better power-to-weight ratio at 0 lbs per hp compared to 1 lbs per hp for the Crestliner Mirage 1800 2006. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Crestliner LSi 2085 2006 measures 102" wide, compared to 95" for the Crestliner Mirage 1800 2006. 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.
Which boat has the larger fuel tank — the Crestliner LSi 2085 2006 or the Crestliner Mirage 1800 2006?
The Crestliner Mirage 1800 2006 has the bigger tank at 39 gallons, versus 25 gallons on the Crestliner LSi 2085 2006. That 14-gallon difference translates to roughly 42–70 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Crestliner LSi 2085 2006 and Crestliner Mirage 1800 2006 from the same manufacturer?
Yes — both the Crestliner LSi 2085 2006 and the Crestliner Mirage 1800 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.
