Sylvan 1700 Avenger DC 2005 vs Sylvan 1800 Avenger SC 2005 - Boat Spec Comparison

Q: Which is the larger boat — the Sylvan 1700 Avenger DC 2005 or the Sylvan 1800 Avenger SC 2005?

The Sylvan 1800 Avenger SC 2005 is the longer of the two at 18,0 feet overall. The Sylvan 1700 Avenger DC 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.

Q: How many people can each boat hold?

The Sylvan 1700 Avenger DC 2005 is Coast Guard rated for 5 passengers, while the Sylvan 1800 Avenger SC 2005 is certified for 6. 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: Do these boats require an oversize trailer permit to tow on US highways?

Both the Sylvan 1700 Avenger DC 2005 and Sylvan 1800 Avenger SC 2005 share an 91 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.

Q: How do the fuel tanks compare on the Sylvan 1700 Avenger DC 2005 and Sylvan 1800 Avenger SC 2005?

Both boats carry similar fuel loads — 31 gallons and 31 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.

Q: Are the Sylvan 1700 Avenger DC 2005 and Sylvan 1800 Avenger SC 2005 from the same manufacturer?

Yes — both the Sylvan 1700 Avenger DC 2005 and the Sylvan 1800 Avenger SC 2005 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.

Detailed Evaluation & Buyer Recommendation

Sylvan 1700 Avenger DC 2005 vs Sylvan 1800 Avenger SC 2005 — Same Brand, Different Boat

The Sylvan 1700 Avenger DC 2005 vs Sylvan 1800 Avenger SC 2005 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 — 135 hp for the Sylvan 1700 Avenger DC 2005 and 135 hp for the Sylvan 1800 Avenger SC 2005. 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 carry nearly identical fuel loads — 31 gal and 31 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sylvan 1800 Avenger SC 2005 is rated for 6 passengers, while the Sylvan 1700 Avenger DC 2005 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sylvan 1800 Avenger SC 2005 could be the deciding factor.

Bottom line: Choose the Sylvan 1800 Avenger SC 2005 if your priority is putting more people on the water — it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Sylvan 1700 Avenger DC 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
