When two boats share the same hull type — in this case both the Alumacraft Dominator 185 Sport 2013 and the Alumacraft Navigator 165 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?

On paper these two are close siblings in the size department — Alumacraft Dominator 185 Sport 2013 at 18,8 ft versus Alumacraft Navigator 165 CS 2012 at 16,7 ft. At 153 lbs and 105 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 150 hp, the Alumacraft Dominator 185 Sport 2013 has a 60-hp advantage over the Alumacraft Navigator 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 Dominator 185 Sport 2013 carries 34 gallons versus 19 gallons in the Alumacraft Navigator 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.
