The Sundance SV186 2011 vs Sundance SV201Bay 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 Sundance SV186 2011 measures 18,5 feet overall (2011), giving it roughly 16,5 additional feet of deck space compared to the Sundance SV201Bay 2007 at 2,0 feet (2007). At 145 lbs and 184 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.
Both boats share a closely matched power ceiling — 150 hp for the Sundance SV186 2011 and 150 hp for the Sundance SV201Bay 2007. 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 — 4 gal and 4 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Sundance SV201Bay 2007 is rated for 6 passengers, while the Sundance SV186 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance SV201Bay 2007 could be the deciding factor.
Bottom line: Choose the Sundance SV201Bay 2007 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Sundance SV186 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
