Detailed Evaluation & Buyer Recommendation
Sylvan Adventurer Series - 1700 DC 2012 vs Sylvan Mirage 8520 4PT Fish 2011 — Same Brand, Different Boat
Matching a modified vee Sylvan Adventurer Series - 1700 DC 2012 against a pontoon Sylvan Mirage 8520 4PT Fish 2011 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Sylvan Mirage 8520 4PT Fish 2011 measures 20,3 feet overall (2011), giving it roughly 3,2 additional feet of deck space compared to the Sylvan Adventurer Series - 1700 DC 2012 at 17,1 feet (2012). Weight tells a clearer story for trailering families: the Sylvan Adventurer Series - 1700 DC 2012 tips the scales at 1 325 lbs — 1 140 lbs more than the Sylvan Mirage 8520 4PT Fish 2011 at 185 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 140 hp, the Sylvan Adventurer Series - 1700 DC 2012 has a 25-hp advantage over the Sylvan Mirage 8520 4PT Fish 2011's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. 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 8520 4PT Fish 2011 is rated for 11 passengers, while the Sylvan Adventurer Series - 1700 DC 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sylvan Mirage 8520 4PT Fish 2011 could be the deciding factor.
Bottom line: Choose the Sylvan Mirage 8520 4PT Fish 2011 if your priority is putting more people on the water — it handles 11 passengers and at 20,3 ft it has the deck room to back that rating up comfortably. The Sylvan Adventurer Series - 1700 DC 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
