Crestliner Sportfish 1750 O/B 2004 vs Crestliner Sportsman 18 2006 - Boat Spec Comparison

Q: Which is easier to trailer — the Crestliner Sportfish 1750 O/B 2004 or the Crestliner Sportsman 18 2006?

For trailering, the Crestliner Sportfish 1750 O/B 2004 has the edge at 13 lbs dry weight versus 61 lbs for the Crestliner Sportsman 18 2006. 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.

Q: Which boat can handle a bigger outboard?

The Crestliner Sportsman 18 2006 is rated to a maximum of 50 hp, giving it the larger power ceiling. The Crestliner Sportfish 1750 O/B 2004 tops out at 14 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.

Q: How many people can each boat hold?

The Crestliner Sportfish 1750 O/B 2004 is Coast Guard rated for 6 passengers, while the Crestliner Sportsman 18 2006 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.

Q: Which boat is wider, and does it affect trailering?

The Crestliner Sportfish 1750 O/B 2004 measures 89" wide, compared to 78" for the Crestliner Sportsman 18 2006. 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.

Q: Are the Crestliner Sportfish 1750 O/B 2004 and Crestliner Sportsman 18 2006 from the same manufacturer?

Yes — both the Crestliner Sportfish 1750 O/B 2004 and the Crestliner Sportsman 18 2006 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.

Detailed Evaluation & Buyer Recommendation

Crestliner Sportfish 1750 O/B 2004 vs Crestliner Sportsman 18 2006 — Same Brand, Different Boat

The Crestliner Sportfish 1750 O/B 2004 vs Crestliner Sportsman 18 2006 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.

The power gap is worth calling out. Rated to 50 hp, the Crestliner Sportsman 18 2006 has a 36-hp advantage over the Crestliner Sportfish 1750 O/B 2004's 14-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Crestliner Sportsman 18 2006 is rated for 7 passengers, while the Crestliner Sportfish 1750 O/B 2004 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Sportsman 18 2006 could be the deciding factor.

Bottom line: Choose the Crestliner Sportsman 18 2006 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 Sportfish 1750 O/B 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
