Crestliner Sportfish 1800 I/O 2007 vs Crestliner Super Hawk 1650 2013: Same Brand, Different Boat

The Crestliner Sportfish 1800 I/O 2007 vs Crestliner Super Hawk 1650 2013 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.

On paper these two are close siblings in the size department - Crestliner Sportfish 1800 I/O 2007 at 18,0 ft versus Crestliner Super Hawk 1650 2013 at 16,3 ft. Weight tells a clearer story for trailering families: the Crestliner Sportfish 1800 I/O 2007 tips the scales at 2 105 lbs - 1 105 lbs more than the Crestliner Super Hawk 1650 2013 at 1 000 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 135 hp, the Crestliner Sportfish 1800 I/O 2007 has a 45-hp advantage over the Crestliner Super Hawk 1650 2013's 90-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 Sportfish 1800 I/O 2007 carries 33 gallons versus 20 gallons in the Crestliner Super Hawk 1650 2013. 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 Sportfish 1800 I/O 2007 is rated for 7 passengers, while the Crestliner Super Hawk 1650 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Sportfish 1800 I/O 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Super Hawk 1650 2013 comes in at 11 lbs per hp versus 16 lbs per hp for the Crestliner Sportfish 1800 I/O 2007. 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.

Bottom line: Choose the Crestliner Sportfish 1800 I/O 2007 if your priority is putting more people on the water - it handles 7 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Crestliner Super Hawk 1650 2013 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 Sportfish 1800 I/O 2007 vs Crestliner Super Hawk 1650 2013 - Common Questions

Which is the larger boat - the Crestliner Sportfish 1800 I/O 2007 or the Crestliner Super Hawk 1650 2013?
The Crestliner Sportfish 1800 I/O 2007 is the longer of the two at 18,0 feet overall. The Crestliner Super Hawk 1650 2013 comes in at 16,3 feet, making it roughly 1,8 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Crestliner Sportfish 1800 I/O 2007 or the Crestliner Super Hawk 1650 2013?
For trailering, the Crestliner Super Hawk 1650 2013 has the edge at 1 000 lbs dry weight versus 2 105 lbs for the Crestliner Sportfish 1800 I/O 2007. 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 Sportfish 1800 I/O 2007 is rated to a maximum of 135 hp, giving it the larger power ceiling. The Crestliner Super Hawk 1650 2013 tops out at 90 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 Sportfish 1800 I/O 2007 is Coast Guard rated for 7 passengers, while the Crestliner Super Hawk 1650 2013 is certified for 6. 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 Super Hawk 1650 2013 has a better power-to-weight ratio at 11 lbs per hp compared to 16 lbs per hp for the Crestliner Sportfish 1800 I/O 2007. 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 Sportfish 1800 I/O 2007 measures 95" wide, compared to 86" for the Crestliner Super Hawk 1650 2013. 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 Sportfish 1800 I/O 2007 or the Crestliner Super Hawk 1650 2013?
The Crestliner Sportfish 1800 I/O 2007 has the bigger tank at 33 gallons, versus 20 gallons on the Crestliner Super Hawk 1650 2013. That 13-gallon difference translates to roughly 39–65 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Crestliner Sportfish 1800 I/O 2007 and Crestliner Super Hawk 1650 2013 from the same manufacturer?
Yes - both the Crestliner Sportfish 1800 I/O 2007 and the Crestliner Super Hawk 1650 2013 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.
