Crestliner C 1756 VS 2005 vs Crestliner Sportsman 18 SS 2008 — Same Brand, Different Boat

The Crestliner C 1756 VS 2005 vs Crestliner Sportsman 18 SS 2008 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 C 1756 VS 2005 at 17,0 ft versus Crestliner Sportsman 18 SS 2008 at 18,0 ft. At 75 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 80 hp, the Crestliner C 1756 VS 2005 has a 30-hp advantage over the Crestliner Sportsman 18 SS 2008's 50-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 SS 2008 is rated for 7 passengers, while the Crestliner C 1756 VS 2005 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Sportsman 18 SS 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner C 1756 VS 2005 comes in at 1 lbs per hp versus 1 lbs per hp for the Crestliner Sportsman 18 SS 2008. 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 Sportsman 18 SS 2008 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 C 1756 VS 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

The Crestliner Sportsman 18 SS 2008 is the longer of the two at 18,0 feet overall. The Crestliner C 1756 VS 2005 comes in at 17,0 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 C 1756 VS 2005 or the Crestliner Sportsman 18 SS 2008?
For trailering, the Crestliner Sportsman 18 SS 2008 has the edge at 67 lbs dry weight versus 75 lbs for the Crestliner C 1756 VS 2005. 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 C 1756 VS 2005 is rated to a maximum of 80 hp, giving it the larger power ceiling. The Crestliner Sportsman 18 SS 2008 tops out at 50 hp.

How many people can each boat hold?
The Crestliner C 1756 VS 2005 is Coast Guard rated for 4 passengers, while the Crestliner Sportsman 18 SS 2008 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 has the better power-to-weight ratio?
The Crestliner C 1756 VS 2005 has a better power-to-weight ratio at 1 lbs per hp compared to 1 lbs per hp for the Crestliner Sportsman 18 SS 2008. 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 Sportsman 18 SS 2008 measures 78" wide, compared to 77" for the Crestliner C 1756 VS 2005. 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.

Yes — both the Crestliner C 1756 VS 2005 and the Crestliner Sportsman 18 SS 2008 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.
