When two boats share the same hull type — in this case both the Alumacraft Dominator 175 Sport 2007 and the Alumacraft MV 2072 AW SC 2013 are modified vee designs with aluminum 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?

Size is the most obvious dividing line here. The Alumacraft Dominator 175 Sport 2007 measures 17,0 feet overall (2007), giving it roughly 15,0 additional feet of deck space compared to the Alumacraft MV 2072 AW SC 2013 at 2,0 feet (2013). Weight tells a clearer story for trailering families: the Alumacraft Dominator 175 Sport 2007 tips the scales at 1 482 lbs — 337 lbs more than the Alumacraft MV 2072 AW SC 2013 at 1 145 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 35-hp advantage over the Alumacraft MV 2072 AW SC 2013's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 4 gal and 2 gal — so range won't be a tiebreaker here.

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 Dominator 175 Sport 2007 comes in at 10 lbs per hp versus 10 lbs per hp for the Alumacraft MV 2072 AW SC 2013. 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.
