Matching a deep vee Alumacraft Dominator 175 Sport 2013 against a modified vee Alumacraft Tournament Pro 185 2006 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 Sport 2013 at 17,8 ft versus Alumacraft Tournament Pro 185 2006 at 18,0 ft. At 1 482 lbs and 1 475 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 power gap is worth calling out. Rated to 150 hp, the Alumacraft Dominator 175 Sport 2013 has a 50-hp advantage over the Alumacraft Tournament Pro 185 2006's 100-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 Tournament Pro 185 2006 carries 41 gallons versus 34 gallons in the Alumacraft Dominator 175 Sport 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 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.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Dominator 175 Sport 2013 comes in at 10 lbs per hp versus 15 lbs per hp for the Alumacraft Tournament Pro 185 2006. 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: Performance buyers should lean toward the Alumacraft Dominator 175 Sport 2013 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Alumacraft Tournament Pro 185 2006 with its 100-hp rating is the more economical daily driver.
