Crestliner Pro Tiller 1850 2011 vs Crestliner Sportfish 1800 I/O 2007 — Same Brand, Different Boat

The Crestliner Pro Tiller 1850 2011 vs Crestliner Sportfish 1800 I/O 2007 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 Pro Tiller 1850 2011 at 18,7 ft versus Crestliner Sportfish 1800 I/O 2007 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Sportfish 1800 I/O 2007 tips the scales at 2 105 lbs — 2 091 lbs less than the Crestliner Pro Tiller 1850 2011 at 14 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 Pro Tiller 1850 2011's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 33 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 Sportfish 1800 I/O 2007 is rated for 7 passengers, while the Crestliner Pro Tiller 1850 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 Sportfish 1800 I/O 2007 could be the deciding factor.

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 Pro Tiller 1850 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 Pro Tiller 1850 2011 vs Crestliner Sportfish 1800 I/O 2007 — Common Questions

Which is the larger boat — the Crestliner Pro Tiller 1850 2011 or the Crestliner Sportfish 1800 I/O 2007?
The Crestliner Pro Tiller 1850 2011 is the longer of the two at 18,7 feet overall. The Crestliner Sportfish 1800 I/O 2007 comes in at 18,0 feet, making it roughly 0,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner Pro Tiller 1850 2011 or the Crestliner Sportfish 1800 I/O 2007?
For trailering, the Crestliner Pro Tiller 1850 2011 has the edge at 14 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 Pro Tiller 1850 2011 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 Pro Tiller 1850 2011 is Coast Guard rated for 6 passengers, while the Crestliner Sportfish 1800 I/O 2007 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 Pro Tiller 1850 2011 measures 96" wide, compared to 95" for the Crestliner Sportfish 1800 I/O 2007. 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 Pro Tiller 1850 2011 and Crestliner Sportfish 1800 I/O 2007?
Both boats carry similar fuel loads — 33 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 Pro Tiller 1850 2011 and Crestliner Sportfish 1800 I/O 2007 from the same manufacturer?
Yes — both the Crestliner Pro Tiller 1850 2011 and the Crestliner Sportfish 1800 I/O 2007 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.
