Crestliner CR 1852MT 2011 vs Crestliner Grand Cayman 2485 I/O 2008 — Same Brand, Different Boat

Matching a flat Crestliner CR 1852MT 2011 against a pontoon Crestliner Grand Cayman 2485 I/O 2008 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 Grand Cayman 2485 I/O 2008 measures 23,0 feet overall (2008), giving it roughly 5,0 additional feet of deck space compared to the Crestliner CR 1852MT 2011 at 18,0 feet (2011). Weight tells a clearer story for trailering families: the Crestliner CR 1852MT 2011 tips the scales at 475 lbs — 473 lbs more than the Crestliner Grand Cayman 2485 I/O 2008 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 Crestliner CR 1852MT 2011 carries a rated maximum of 45 hp. Engine data for the Crestliner Grand Cayman 2485 I/O 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

For family outings this is probably the sharpest distinction between the two. The Crestliner Grand Cayman 2485 I/O 2008 is rated for 12 passengers, while the Crestliner CR 1852MT 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Grand Cayman 2485 I/O 2008 could be the deciding factor.

Bottom line: Choose the Crestliner Grand Cayman 2485 I/O 2008 if your priority is putting more people on the water — it handles 12 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Crestliner CR 1852MT 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Crestliner CR 1852MT 2011 vs Crestliner Grand Cayman 2485 I/O 2008 — Common Questions

Which is the larger boat — the Crestliner CR 1852MT 2011 or the Crestliner Grand Cayman 2485 I/O 2008?
The Crestliner Grand Cayman 2485 I/O 2008 is the longer of the two at 23,0 feet overall. The Crestliner CR 1852MT 2011 comes in at 18,0 feet, making it roughly 5,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner CR 1852MT 2011 or the Crestliner Grand Cayman 2485 I/O 2008?
For trailering, the Crestliner Grand Cayman 2485 I/O 2008 has the edge at 2 lbs dry weight versus 475 lbs for the Crestliner CR 1852MT 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.
What is the maximum horsepower rating for these boats?
The Crestliner CR 1852MT 2011 has a documented max rating of 45 hp. Engine specifications for the Crestliner Grand Cayman 2485 I/O 2008 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Crestliner CR 1852MT 2011 is Coast Guard rated for 6 passengers, while the Crestliner Grand Cayman 2485 I/O 2008 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 Grand Cayman 2485 I/O 2008 measures 102" wide, compared to 75" for the Crestliner CR 1852MT 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 CR 1852MT 2011 and Crestliner Grand Cayman 2485 I/O 2008 from the same manufacturer?
Yes — both the Crestliner CR 1852MT 2011 and the Crestliner Grand Cayman 2485 I/O 2008 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.
