When two boats share the same hull type — in this case both the Vectra 2040 IO Fish 2008 and the Vectra V-162 OB 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 V-162 OB 2008 measures 15,0 feet overall (2008), giving it roughly 13,0 additional feet of deck space compared to the Vectra 2040 IO Fish 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the Vectra 2040 IO Fish 2008 tips the scales at 2 325 lbs — 2 183 lbs more than the Vectra V-162 OB 2008 at 142 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.
For family outings this is probably the sharpest distinction between the two. The Vectra 2040 IO Fish 2008 is rated for 12 passengers, while the Vectra V-162 OB 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Vectra 2040 IO Fish 2008 could be the deciding factor.
Bottom line: Choose the Vectra 2040 IO Fish 2008 if your priority is putting more people on the water — it handles 12 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Vectra V-162 OB 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
