When two boats share the same hull type — in this case both the Vectra S-190 OB 2007 and the Vectra V-172 OB 2007 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department — Vectra S-190 OB 2007 at 19,0 ft versus Vectra V-172 OB 2007 at 16,0 ft. At 225 lbs and 152 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 — 115 hp for the Vectra S-190 OB 2007 and 130 hp for the Vectra V-172 OB 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. Fuel capacity breaks the other way: the Vectra S-190 OB 2007 carries 51 gallons versus 23 gallons in the Vectra V-172 OB 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Vectra V-172 OB 2007 is rated for 8 passengers, while the Vectra S-190 OB 2007 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Vectra V-172 OB 2007 could be the deciding factor.
Bottom line: Choose the Vectra V-172 OB 2007 if your priority is putting more people on the water — it handles 8 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Vectra S-190 OB 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
