When two boats share the same hull type — in this case both the Alumacraft Dominator 175 Sport 2007 and the Alumacraft MV 1546 AW 2010 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?

On paper these two are close siblings in the size department — Alumacraft Dominator 175 Sport 2007 at 17,0 ft versus Alumacraft MV 1546 AW 2010 at 15,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Dominator 175 Sport 2007 tips the scales at 1 482 lbs — 1 448 lbs more than the Alumacraft MV 1546 AW 2010 at 34 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 125-hp advantage over the Alumacraft MV 1546 AW 2010's 25-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Dominator 175 Sport 2007 is rated for 5 passengers, while the Alumacraft MV 1546 AW 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Dominator 175 Sport 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft MV 1546 AW 2010 comes in at 1 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.
