When two boats share the same hull type — in this case both the Vectra 2090 OB 2010 and the Vectra V-172 IO Sport 2008 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?
Size is the most obvious dividing line here. The Vectra 2090 OB 2010 measures 20,3 feet overall (2010), giving it roughly 4,3 additional feet of deck space compared to the Vectra V-172 IO Sport 2008 at 16,0 feet (2008). Weight tells a clearer story for trailering families: the Vectra 2090 OB 2010 tips the scales at 2 405 lbs — 2 250 lbs more than the Vectra V-172 IO Sport 2008 at 155 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 Vectra 2090 OB 2010 carries a rated maximum of 225 hp. Engine data for the Vectra V-172 IO Sport 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Vectra 2090 OB 2010 carries 51 gallons versus 23 gallons in the Vectra V-172 IO Sport 2008. 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 2090 OB 2010 is rated for 12 passengers, while the Vectra V-172 IO Sport 2008 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Vectra 2090 OB 2010 could be the deciding factor.
Bottom line: Choose the Vectra 2090 OB 2010 if your priority is putting more people on the water — it handles 12 passengers and at 20,3 ft it has the deck room to back that rating up comfortably. The Vectra V-172 IO Sport 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
