When two boats share the same hull type — in this case both the Alumacraft Dominator 185 Sport 2012 and the Alumacraft Fisherman 145 CS 2012 are deep 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 185 Sport 2012 measures 18,8 feet overall (2012), giving it roughly 3,9 additional feet of deck space compared to the Alumacraft Fisherman 145 CS 2012 at 14,8 feet (2012). Weight tells a clearer story for trailering families: the Alumacraft Fisherman 145 CS 2012 tips the scales at 602 lbs — 449 lbs less than the Alumacraft Dominator 185 Sport 2012 at 153 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 185 Sport 2012 has a 120-hp advantage over the Alumacraft Fisherman 145 CS 2012's 30-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 185 Sport 2012 is rated for 6 passengers, while the Alumacraft Fisherman 145 CS 2012 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 185 Sport 2012 could be the deciding factor.
