When two boats share the same hull type — in this case both the Vectra 1580 CR 2009 and the Vectra 1900 CR 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 1900 CR 2008 measures 19,0 feet overall (2008), giving it roughly 4,0 additional feet of deck space compared to the Vectra 1580 CR 2009 at 15,0 feet (2009). Weight tells a clearer story for trailering families: the Vectra 1900 CR 2008 tips the scales at 2 718 lbs — 770 lbs less than the Vectra 1580 CR 2009 at 1 948 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 1580 CR 2009 carries a rated maximum of 115 hp. Engine data for the Vectra 1900 CR 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 1580 CR 2009 carries 31 gallons versus 5 gallons in the Vectra 1900 CR 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 1580 CR 2009 is rated for 9 passengers, while the Vectra 1900 CR 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 1580 CR 2009 could be the deciding factor.
Bottom line: Choose the Vectra 1580 CR 2009 if your priority is putting more people on the water — it handles 9 passengers and at 15,0 ft it has the deck room to back that rating up comfortably. The Vectra 1900 CR 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.
