When two boats share the same hull type — in this case both the Vectra 1900 F 2008 and the Vectra V172 I/O 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 1900 F 2008 at 19,0 ft versus Vectra V172 I/O 2010 at 16,8 ft. Weight tells a clearer story for trailering families: the Vectra 1900 F 2008 tips the scales at 2 718 lbs — 2 563 lbs more than the Vectra V172 I/O 2010 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.
Both boats share a closely matched power ceiling — 200 hp for the Vectra 1900 F 2008 and 220 hp for the Vectra V172 I/O 2010. 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 V172 I/O 2010 carries 23 gallons versus 5 gallons in the Vectra 1900 F 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 V172 I/O 2010 is rated for 8 passengers, while the Vectra 1900 F 2008 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 I/O 2010 could be the deciding factor.
Bottom line: Choose the Vectra V172 I/O 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 1900 F 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
