When two boats share the same hull type — in this case both the Vectra V-192 IO Fish-n-Ski 2009 and the Vectra V172 OB 2010 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 V-192 IO Fish-n-Ski 2009 at 19,0 ft versus Vectra V172 OB 2010 at 16,8 ft. Weight tells a clearer story for trailering families: the Vectra V172 OB 2010 tips the scales at 152 lbs — 135 lbs less than the Vectra V-192 IO Fish-n-Ski 2009 at 17 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 260 hp, the Vectra V-192 IO Fish-n-Ski 2009 has a 125-hp advantage over the Vectra V172 OB 2010's 135-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Vectra V-192 IO Fish-n-Ski 2009 carries 37 gallons versus 23 gallons in the Vectra V172 OB 2010. 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 V172 OB 2010 is rated for 8 passengers, while the Vectra V-192 IO Fish-n-Ski 2009 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Vectra V172 OB 2010 could be the deciding factor.
Bottom line: Choose the Vectra V172 OB 2010 if your priority is putting more people on the water — it handles 8 passengers and at 16,8 ft it has the deck room to back that rating up comfortably. The Vectra V-192 IO Fish-n-Ski 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
