Matching a deep vee Alumacraft Dominator 165 CS 2012 against a modified vee Alumacraft Tournament Sport 175 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 165 CS 2012 at 16,7 ft versus Alumacraft Tournament Sport 175 2006 at 17,0 ft. At 125 lbs and 153 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 175 hp, the Alumacraft Tournament Sport 175 2006 has a 85-hp advantage over the Alumacraft Dominator 165 CS 2012'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 Tournament Sport 175 2006 carries 34 gallons versus 19 gallons in the Alumacraft Dominator 165 CS 2012. 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 Tournament Sport 175 2006 comes in at 1 lbs per hp versus 1 lbs per hp for the Alumacraft Dominator 165 CS 2012. 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.
