Crestliner Sportfish 1950 O/B 2006 vs Crestliner Sportsmen Series 18 SS 2009 — Same Brand, Different Boat

The Crestliner Sportfish 1950 O/B 2006 vs Crestliner Sportsmen Series 18 SS 2009 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 1950 O/B 2006 at 19,0 ft versus Crestliner Sportsmen Series 18 SS 2009 at 18,0 ft. At 18 lbs and 67 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 200 hp, the Crestliner Sportfish 1950 O/B 2006 has a 150-hp advantage over the Crestliner Sportsmen Series 18 SS 2009's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 7 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the Crestliner Sportfish 1950 O/B 2006 and its 200-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Crestliner Sportsmen Series 18 SS 2009 with its 50-hp rating is the more economical daily driver.

Crestliner Sportfish 1950 O/B 2006 vs Crestliner Sportsmen Series 18 SS 2009 — Common Questions

Which is the larger boat — the Crestliner Sportfish 1950 O/B 2006 or the Crestliner Sportsmen Series 18 SS 2009?
The Crestliner Sportfish 1950 O/B 2006 is the longer of the two at 19,0 feet overall. The Crestliner Sportsmen Series 18 SS 2009 comes in at 18,0 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner Sportfish 1950 O/B 2006 or the Crestliner Sportsmen Series 18 SS 2009?
For trailering, the Crestliner Sportfish 1950 O/B 2006 has the edge at 18 lbs dry weight versus 67 lbs for the Crestliner Sportsmen Series 18 SS 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 Sportfish 1950 O/B 2006 is rated to a maximum of 200 hp, giving it the larger power ceiling. The Crestliner Sportsmen Series 18 SS 2009 tops out at 50 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 1950 O/B 2006 is Coast Guard rated for 7 passengers, while the Crestliner Sportsmen Series 18 SS 2009 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 Sportsmen Series 18 SS 2009 measures 78" wide, compared to 1" for the Crestliner Sportfish 1950 O/B 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.
Are the Crestliner Sportfish 1950 O/B 2006 and Crestliner Sportsmen Series 18 SS 2009 from the same manufacturer?
Yes — both the Crestliner Sportfish 1950 O/B 2006 and the Crestliner Sportsmen Series 18 SS 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.
