When two boats share the same hull type — in this case both the Vectra V-172 IO Sport 2008 and the Vectra V-172 OB Fish 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 V-172 IO Sport 2008 at 16,0 ft versus Vectra V-172 OB Fish 2007 at 16,0 ft. At 155 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.
The Vectra V-172 OB Fish 2007 tops out at 130 hp. Engine specs for the Vectra V-172 IO Sport 2008 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 23 gal and 23 gal — so range won't be a tiebreaker here.
Both boats are rated for 8 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Vectra V-172 IO Sport 2008 and Vectra V-172 OB Fish 2007 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
