Matching a deep vee Alumacraft Navigator 175 Sport 2012 against a modified vee Alumacraft Tournament Sport 175 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 Navigator 175 Sport 2012 at 17,7 ft versus Alumacraft Tournament Sport 175 2006 at 17,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Navigator 175 Sport 2012 tips the scales at 1 357 lbs — 1 204 lbs more than the Alumacraft Tournament Sport 175 2006 at 153 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 175 hp, the Alumacraft Tournament Sport 175 2006 has a 25-hp advantage over the Alumacraft Navigator 175 Sport 2012's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 35 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Tournament Sport 175 2006 comes in at 1 lbs per hp versus 9 lbs per hp for the Alumacraft Navigator 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.
