The Sundance FX19 Vapor 2013 vs Sundance SV171Bay 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 — Sundance FX19 Vapor 2013 at 19,1 ft versus Sundance SV171Bay 2007 at 17,0 ft. At 102 lbs and 155 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 150 hp, the Sundance FX19 Vapor 2013 has a 60-hp advantage over the Sundance SV171Bay 2007's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 31 gal and 34 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Sundance SV171Bay 2007 is rated for 5 passengers, while the Sundance FX19 Vapor 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance SV171Bay 2007 could be the deciding factor.
Bottom line: Choose the Sundance SV171Bay 2007 if your priority is putting more people on the water — it handles 5 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Sundance FX19 Vapor 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
