Crestliner CR 1648 MTS 2004 vs Crestliner Sportsmen Series 18 SS SC 2009 - Boat Spec Comparison

Q: Which is easier to trailer — the Crestliner CR 1648 MTS 2004 or the Crestliner Sportsmen Series 18 SS SC 2009?

For trailering, the Crestliner Sportsmen Series 18 SS SC 2009 has the edge at 67 lbs dry weight versus 275 lbs for the Crestliner CR 1648 MTS 2004. 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 Sportsmen Series 18 SS SC 2009 is rated to a maximum of 50 hp, giving it the larger power ceiling. The Crestliner CR 1648 MTS 2004 tops out at 35 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 CR 1648 MTS 2004 is Coast Guard rated for 4 passengers, while the Crestliner Sportsmen Series 18 SS SC 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.

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

The Crestliner Sportsmen Series 18 SS SC 2009 measures 78" wide, compared to 7" for the Crestliner CR 1648 MTS 2004. 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 CR 1648 MTS 2004 and Crestliner Sportsmen Series 18 SS SC 2009 from the same manufacturer?

Yes — both the Crestliner CR 1648 MTS 2004 and the Crestliner Sportsmen Series 18 SS SC 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.

Detailed Evaluation & Buyer Recommendation

Crestliner CR 1648 MTS 2004 vs Crestliner Sportsmen Series 18 SS SC 2009 — Same Brand, Different Boat

The Crestliner CR 1648 MTS 2004 vs Crestliner Sportsmen Series 18 SS SC 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.

Both boats share a closely matched power ceiling — 35 hp for the Crestliner CR 1648 MTS 2004 and 50 hp for the Crestliner Sportsmen Series 18 SS SC 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

For family outings this is probably the sharpest distinction between the two. The Crestliner Sportsmen Series 18 SS SC 2009 is rated for 7 passengers, while the Crestliner CR 1648 MTS 2004 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Sportsmen Series 18 SS SC 2009 could be the deciding factor.

Bottom line: Choose the Crestliner Sportsmen Series 18 SS SC 2009 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 CR 1648 MTS 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
