Sylvan 1600 Avenger SC 2004 vs Sylvan Mirage Fish 820 4-PT 2012 — Same Brand, Different Boat

The Sylvan 1600 Avenger SC 2004 vs Sylvan Mirage Fish 820 4-PT 2012 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 — 90 hp for the Sylvan 1600 Avenger SC 2004 and 90 hp for the Sylvan Mirage Fish 820 4-PT 2012. 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 — 24 gal and 24 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sylvan Mirage Fish 820 4-PT 2012 is rated for 6 passengers, while the Sylvan 1600 Avenger SC 2004 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sylvan Mirage Fish 820 4-PT 2012 could be the deciding factor.

Bottom line: Choose the Sylvan Mirage Fish 820 4-PT 2012 if your priority is putting more people on the water — it handles 6 passengers and at 20,8 ft it has the deck room to back that rating up comfortably. The Sylvan 1600 Avenger SC 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
