When two boats share the same hull type — in this case both the Alumacraft Competitor 175 Tiller 2013 and the Alumacraft Dominator 185 CS 2013 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 Competitor 175 Tiller 2013 at 17,7 ft versus Alumacraft Dominator 185 CS 2013 at 18,8 ft. Weight tells a clearer story for trailering families: the Alumacraft Dominator 185 CS 2013 tips the scales at 1 438 lbs — 1 322 lbs less than the Alumacraft Competitor 175 Tiller 2013 at 116 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 CS 2013 has a 75-hp advantage over the Alumacraft Competitor 175 Tiller 2013's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 34 gal and 34 gal — so range won't be a tiebreaker here.

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.
