Sylvan 1800 Avenger DC 2005 vs Sylvan Pro Sport 1900 DC 2007 — Same Brand, Different Boat

The Sylvan 1800 Avenger DC 2005 vs Sylvan Pro Sport 1900 DC 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 — Sylvan 1800 Avenger DC 2005 at 18,0 ft versus Sylvan Pro Sport 1900 DC 2007 at 18,0 ft. At 127 lbs and 145 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 175 hp, the Sylvan Pro Sport 1900 DC 2007 has a 25-hp advantage over the Sylvan 1800 Avenger DC 2005's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sylvan 1800 Avenger DC 2005 carries 31 gallons versus 4 gallons in the Sylvan Pro Sport 1900 DC 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Sylvan Pro Sport 1900 DC 2007 is rated for 8 passengers, while the Sylvan 1800 Avenger DC 2005 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sylvan Pro Sport 1900 DC 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Sylvan Pro Sport 1900 DC 2007 comes in at 1 lbs per hp versus 1 lbs per hp for the Sylvan 1800 Avenger DC 2005. 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 Sylvan Pro Sport 1900 DC 2007 if your priority is putting more people on the water — it handles 8 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Sylvan 1800 Avenger DC 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Sylvan 1800 Avenger DC 2005 vs Sylvan Pro Sport 1900 DC 2007 — Common Questions

The Sylvan Pro Sport 1900 DC 2007 is the longer of the two at 18,0 feet overall. The Sylvan 1800 Avenger DC 2005 comes in at 18,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sylvan 1800 Avenger DC 2005 or the Sylvan Pro Sport 1900 DC 2007?
For trailering, the Sylvan 1800 Avenger DC 2005 has the edge at 127 lbs dry weight versus 145 lbs for the Sylvan Pro Sport 1900 DC 2007. 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 Sylvan Pro Sport 1900 DC 2007 is rated to a maximum of 175 hp, giving it the larger power ceiling. The Sylvan 1800 Avenger DC 2005 tops out at 150 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 Sylvan 1800 Avenger DC 2005 is Coast Guard rated for 6 passengers, while the Sylvan Pro Sport 1900 DC 2007 is certified for 8. 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 Sylvan Pro Sport 1900 DC 2007 has a better power-to-weight ratio at 1 lbs per hp compared to 1 lbs per hp for the Sylvan 1800 Avenger DC 2005. 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 Sylvan Pro Sport 1900 DC 2007 measures 96" wide, compared to 91" for the Sylvan 1800 Avenger DC 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.

The Sylvan 1800 Avenger DC 2005 has the bigger tank at 31 gallons, versus 4 gallons on the Sylvan Pro Sport 1900 DC 2007. That 27-gallon difference translates to roughly 81–135 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sylvan 1800 Avenger DC 2005 and Sylvan Pro Sport 1900 DC 2007 from the same manufacturer?
Yes — both the Sylvan 1800 Avenger DC 2005 and the Sylvan Pro Sport 1900 DC 2007 are built by Sylvan. 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.
