Crestliner Fish Hawk 1700 SC 2008 vs Crestliner Grand Cayman 2685 I/O 2009 — Same Brand, Different Boat

Matching a modified vee Crestliner Fish Hawk 1700 SC 2008 against a pontoon Crestliner Grand Cayman 2685 I/O 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 Grand Cayman 2685 I/O 2009 measures 25,0 feet overall (2009), giving it roughly 8,0 additional feet of deck space compared to the Crestliner Fish Hawk 1700 SC 2008 at 17,0 feet (2008). At 11 lbs and 34 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 Fish Hawk 1700 SC 2008 has a 112-hp advantage over the Crestliner Grand Cayman 2685 I/O 2009's 3-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 Grand Cayman 2685 I/O 2009 carries 35 gallons versus 3 gallons in the Crestliner Fish Hawk 1700 SC 2008. 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 Grand Cayman 2685 I/O 2009 is rated for 14 passengers, while the Crestliner Fish Hawk 1700 SC 2008 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 2685 I/O 2009 could be the deciding factor.

Bottom line: Choose the Crestliner Grand Cayman 2685 I/O 2009 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 Fish Hawk 1700 SC 2008 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 Fish Hawk 1700 SC 2008 vs Crestliner Grand Cayman 2685 I/O 2009 — Common Questions

Which is the larger boat — the Crestliner Fish Hawk 1700 SC 2008 or the Crestliner Grand Cayman 2685 I/O 2009?
The Crestliner Grand Cayman 2685 I/O 2009 is the longer of the two at 25,0 feet overall. The Crestliner Fish Hawk 1700 SC 2008 comes in at 17,0 feet, making it roughly 8,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner Fish Hawk 1700 SC 2008 or the Crestliner Grand Cayman 2685 I/O 2009?
For trailering, the Crestliner Fish Hawk 1700 SC 2008 has the edge at 11 lbs dry weight versus 34 lbs for the Crestliner Grand Cayman 2685 I/O 2009. 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 Fish Hawk 1700 SC 2008 is rated to a maximum of 115 hp, giving it the larger power ceiling. The Crestliner Grand Cayman 2685 I/O 2009 tops out at 3 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 Fish Hawk 1700 SC 2008 is Coast Guard rated for 6 passengers, while the Crestliner Grand Cayman 2685 I/O 2009 is certified for 14. 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 2685 I/O 2009 measures 102" wide, compared to 91" for the Crestliner Fish Hawk 1700 SC 2008. 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 Fish Hawk 1700 SC 2008 or the Crestliner Grand Cayman 2685 I/O 2009?
The Crestliner Grand Cayman 2685 I/O 2009 has the bigger tank at 35 gallons, versus 3 gallons on the Crestliner Fish Hawk 1700 SC 2008. That 32-gallon difference translates to roughly 96–160 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Crestliner Fish Hawk 1700 SC 2008 and Crestliner Grand Cayman 2685 I/O 2009 from the same manufacturer?
Yes — both the Crestliner Fish Hawk 1700 SC 2008 and the Crestliner Grand Cayman 2685 I/O 2009 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.
