Crestliner Serenity 1800 2005 vs Crestliner Sportsman 14 SC 2007 — Same Brand, Different Boat

The Crestliner Serenity 1800 2005 vs Crestliner Sportsman 14 SC 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.

Size is the most obvious dividing line here. The Crestliner Serenity 1800 2005 measures 18,0 feet overall (2005), giving it roughly 4,0 additional feet of deck space compared to the Crestliner Sportsman 14 SC 2007 at 14,0 feet (2007). Weight tells a clearer story for trailering families: the Crestliner Serenity 1800 2005 tips the scales at 147 lbs — 106 lbs more than the Crestliner Sportsman 14 SC 2007 at 41 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.

The power gap is worth calling out. Rated to 175 hp, the Crestliner Serenity 1800 2005 has a 140-hp advantage over the Crestliner Sportsman 14 SC 2007's 35-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 Serenity 1800 2005 is rated for 7 passengers, while the Crestliner Sportsman 14 SC 2007 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Serenity 1800 2005 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Serenity 1800 2005 comes in at 1 lbs per hp versus 1 lbs per hp for the Crestliner Sportsman 14 SC 2007. 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 Serenity 1800 2005 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 Sportsman 14 SC 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

Crestliner Serenity 1800 2005 vs Crestliner Sportsman 14 SC 2007 — Common Questions

The Crestliner Serenity 1800 2005 is the longer of the two at 18,0 feet overall. The Crestliner Sportsman 14 SC 2007 comes in at 14,0 feet, making it roughly 4,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner Serenity 1800 2005 or the Crestliner Sportsman 14 SC 2007?
For trailering, the Crestliner Sportsman 14 SC 2007 has the edge at 41 lbs dry weight versus 147 lbs for the Crestliner Serenity 1800 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 Serenity 1800 2005 is rated to a maximum of 175 hp, giving it the larger power ceiling. The Crestliner Sportsman 14 SC 2007 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.
How many people can each boat hold?
The Crestliner Serenity 1800 2005 is Coast Guard rated for 7 passengers, while the Crestliner Sportsman 14 SC 2007 is certified for 4. 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 Serenity 1800 2005 has a better power-to-weight ratio at 1 lbs per hp compared to 1 lbs per hp for the Crestliner Sportsman 14 SC 2007. 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 Serenity 1800 2005 measures 95" wide, compared to 73" for the Crestliner Sportsman 14 SC 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 Serenity 1800 2005 and Crestliner Sportsman 14 SC 2007 from the same manufacturer?
Yes — both the Crestliner Serenity 1800 2005 and the Crestliner Sportsman 14 SC 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.
