When two boats share the same hull type — in this case both the Vectra 1900 C - Space Deck 2007 and the Vectra S-190 OB 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 1900 C - Space Deck 2007 at 19,0 ft versus Vectra S-190 OB 2007 at 19,0 ft. Weight tells a clearer story for trailering families: the Vectra 1900 C - Space Deck 2007 tips the scales at 2 718 lbs — 2 493 lbs more than the Vectra S-190 OB 2007 at 225 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 200 hp, the Vectra 1900 C - Space Deck 2007 has a 85-hp advantage over the Vectra S-190 OB 2007's 115-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 S-190 OB 2007 carries 51 gallons versus 5 gallons in the Vectra 1900 C - Space Deck 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 1 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.
