Matching a deep vee Alumacraft Competitor 175 Tiller 2013 against a modified vee Alumacraft Navigator 185 Sport 2006 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Alumacraft Competitor 175 Tiller 2013 at 17,7 ft versus Alumacraft Navigator 185 Sport 2006 at 18,0 ft. At 116 lbs and 144 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 Navigator 185 Sport 2006 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. Fuel capacity breaks the other way: the Alumacraft Competitor 175 Tiller 2013 carries 34 gallons versus 4 gallons in the Alumacraft Navigator 185 Sport 2006. 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 Navigator 185 Sport 2006 comes in at 1 lbs per hp versus 2 lbs per hp for the Alumacraft Competitor 175 Tiller 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.
