Matching a deep vee Alumacraft Competitor 175 Sport 2012 against a modified vee Alumacraft Navigator 175 CS 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 Sport 2012 at 17,7 ft versus Alumacraft Navigator 175 CS 2006 at 17,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Competitor 175 Sport 2012 tips the scales at 1 375 lbs — 130 lbs more than the Alumacraft Navigator 175 CS 2006 at 1 245 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.

Both boats share a closely matched power ceiling — 150 hp for the Alumacraft Competitor 175 Sport 2012 and 140 hp for the Alumacraft Navigator 175 CS 2006. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Alumacraft Competitor 175 Sport 2012 carries 35 gallons versus 4 gallons in the Alumacraft Navigator 175 CS 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 5 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 175 CS 2006 comes in at 9 lbs per hp versus 9 lbs per hp for the Alumacraft Competitor 175 Sport 2012. 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.
