Matching a modified vee Alumacraft Dominator 175 CS 2007 against a flat Alumacraft VB 1860 AW Tunnel SC 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Alumacraft Dominator 175 CS 2007 at 17,0 ft versus Alumacraft VB 1860 AW Tunnel SC 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Alumacraft VB 1860 AW Tunnel SC 2008 tips the scales at 875 lbs — 736 lbs less than the Alumacraft Dominator 175 CS 2007 at 139 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 150 hp, the Alumacraft Dominator 175 CS 2007 has a 60-hp advantage over the Alumacraft VB 1860 AW Tunnel SC 2008's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Alumacraft VB 1860 AW Tunnel SC 2008 carries 16 gallons versus 4 gallons in the Alumacraft Dominator 175 CS 2007. 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 Alumacraft VB 1860 AW Tunnel SC 2008 is rated for 6 passengers, while the Alumacraft Dominator 175 CS 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft VB 1860 AW Tunnel SC 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Dominator 175 CS 2007 comes in at 1 lbs per hp versus 10 lbs per hp for the Alumacraft VB 1860 AW Tunnel SC 2008. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Alumacraft VB 1860 AW Tunnel SC 2008 if your priority is putting more people on the water — it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Alumacraft Dominator 175 CS 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
