Crestliner Sport Classic 1680 2004 vs Crestliner Sportsman 18 2007 — Same Brand, Different Boat

The Crestliner Sport Classic 1680 2004 vs Crestliner Sportsman 18 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 Sport Classic 1680 2004 at 16,0 ft versus Crestliner Sportsman 18 2007 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner Sport Classic 1680 2004 tips the scales at 1 425 lbs — 1 364 lbs more than the Crestliner Sportsman 18 2007 at 61 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.

Both boats share a closely matched power ceiling — 50 hp for the Crestliner Sport Classic 1680 2004 and 50 hp for the Crestliner Sportsman 18 2007. 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.

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.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Sportsman 18 2007 comes in at 1 lbs per hp versus 29 lbs per hp for the Crestliner Sport Classic 1680 2004. 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: The Crestliner Sport Classic 1680 2004 and Crestliner Sportsman 18 2007 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Crestliner Sport Classic 1680 2004 vs Crestliner Sportsman 18 2007 — Common Questions

Which is the larger boat — the Crestliner Sport Classic 1680 2004 or the Crestliner Sportsman 18 2007?
The Crestliner Sportsman 18 2007 is the longer of the two at 18,0 feet overall. The Crestliner Sport Classic 1680 2004 comes in at 16,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner Sport Classic 1680 2004 or the Crestliner Sportsman 18 2007?
For trailering, the Crestliner Sportsman 18 2007 has the edge at 61 lbs dry weight versus 1 425 lbs for the Crestliner Sport Classic 1680 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.
How many people can each boat hold?
The Crestliner Sport Classic 1680 2004 is Coast Guard rated for 7 passengers, while the Crestliner Sportsman 18 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 has the better power-to-weight ratio?
The Crestliner Sportsman 18 2007 has a better power-to-weight ratio at 1 lbs per hp compared to 29 lbs per hp for the Crestliner Sport Classic 1680 2004. 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 Sport Classic 1680 2004 measures 96" wide, compared to 78" for the Crestliner Sportsman 18 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.
Are the Crestliner Sport Classic 1680 2004 and Crestliner Sportsman 18 2007 from the same manufacturer?
Yes — both the Crestliner Sport Classic 1680 2004 and the Crestliner Sportsman 18 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.
