Crestliner LSi 2685 Sterndrive 2006 vs Crestliner Super Hawk 1800 I/O 2010 — Same Brand, Different Boat

The Crestliner LSi 2685 Sterndrive 2006 vs Crestliner Super Hawk 1800 I/O 2010 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 LSi 2685 Sterndrive 2006 measures 25,0 feet overall (2006), giving it roughly 6,8 additional feet of deck space compared to the Crestliner Super Hawk 1800 I/O 2010 at 18,2 feet (2010). Weight tells a clearer story for trailering families: the Crestliner Super Hawk 1800 I/O 2010 tips the scales at 2 105 lbs — 2 071 lbs less than the Crestliner LSi 2685 Sterndrive 2006 at 34 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 260 hp, the Crestliner LSi 2685 Sterndrive 2006 has a 40-hp advantage over the Crestliner Super Hawk 1800 I/O 2010's 220-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 35 gal and 33 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Crestliner LSi 2685 Sterndrive 2006 is rated for 14 passengers, while the Crestliner Super Hawk 1800 I/O 2010 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 2685 Sterndrive 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner LSi 2685 Sterndrive 2006 comes in at 0 lbs per hp versus 10 lbs per hp for the Crestliner Super Hawk 1800 I/O 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.

The Crestliner LSi 2685 Sterndrive 2006 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Crestliner Super Hawk 1800 I/O 2010 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 2685 Sterndrive 2006 if your priority is putting more people on the water — it handles 14 passengers and at 25,0 ft it has the deck room to back that rating up comfortably. The Crestliner Super Hawk 1800 I/O 2010 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 2685 Sterndrive 2006 vs Crestliner Super Hawk 1800 I/O 2010 — Common Questions

Which is the larger boat — the Crestliner LSi 2685 Sterndrive 2006 or the Crestliner Super Hawk 1800 I/O 2010?
The Crestliner LSi 2685 Sterndrive 2006 is the longer of the two at 25,0 feet overall. The Crestliner Super Hawk 1800 I/O 2010 comes in at 18,2 feet, making it roughly 6,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner LSi 2685 Sterndrive 2006 or the Crestliner Super Hawk 1800 I/O 2010?
For trailering, the Crestliner LSi 2685 Sterndrive 2006 has the edge at 34 lbs dry weight versus 2 105 lbs for the Crestliner Super Hawk 1800 I/O 2010. 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 2685 Sterndrive 2006 is rated to a maximum of 260 hp, giving it the larger power ceiling. The Crestliner Super Hawk 1800 I/O 2010 tops out at 220 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 2685 Sterndrive 2006 is Coast Guard rated for 14 passengers, while the Crestliner Super Hawk 1800 I/O 2010 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 is wider, and does it affect trailering?
The Crestliner LSi 2685 Sterndrive 2006 measures 102" wide, compared to 95" for the Crestliner Super Hawk 1800 I/O 2010. 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.
How do the fuel tanks compare on the Crestliner LSi 2685 Sterndrive 2006 and Crestliner Super Hawk 1800 I/O 2010?
Both boats carry similar fuel loads — 35 gallons and 33 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Crestliner LSi 2685 Sterndrive 2006 and Crestliner Super Hawk 1800 I/O 2010 from the same manufacturer?
Yes — both the Crestliner LSi 2685 Sterndrive 2006 and the Crestliner Super Hawk 1800 I/O 2010 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.
