Matching a modified vee Alumacraft Dominator 175 Sport 2007 against a deep vee Alumacraft Lunker 165 CS 2011 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 2007 at 17,0 ft versus Alumacraft Lunker 165 CS 2011 at 16,5 ft. Weight tells a clearer story for trailering families: the Alumacraft Dominator 175 Sport 2007 tips the scales at 1 482 lbs — 1 408 lbs more than the Alumacraft Lunker 165 CS 2011 at 74 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 Sport 2007 has a 110-hp advantage over the Alumacraft Lunker 165 CS 2011's 40-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 Lunker 165 CS 2011 carries 8 gallons versus 4 gallons in the Alumacraft Dominator 175 Sport 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 5 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 Lunker 165 CS 2011 comes in at 2 lbs per hp versus 10 lbs per hp for the Alumacraft Dominator 175 Sport 2007. 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 2007 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Alumacraft Lunker 165 CS 2011 with its 40-hp rating is the more economical daily driver.
