When two boats share the same hull type — in this case both the Alumacraft Competitor 165 Tiller 2013 and the Alumacraft Competitor 175 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 165 Tiller 2013 at 16,6 ft versus Alumacraft Competitor 175 CS 2013 at 17,7 ft. Weight tells a clearer story for trailering families: the Alumacraft Competitor 175 CS 2013 tips the scales at 1 285 lbs — 1 193 lbs less than the Alumacraft Competitor 165 Tiller 2013 at 92 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 Competitor 175 CS 2013 has a 80-hp advantage over the Alumacraft Competitor 165 Tiller 2013's 70-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 Competitor 175 CS 2013 carries 34 gallons versus 17 gallons in the Alumacraft Competitor 165 Tiller 2013. 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Competitor 165 Tiller 2013 comes in at 1 lbs per hp versus 9 lbs per hp for the Alumacraft Competitor 175 CS 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.
