The Alumacraft Navigator 175 CS 2013 vs Alumacraft Tournament Pro 175 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Alumacraft Navigator 175 CS 2013 at 17,7 ft versus Alumacraft Tournament Pro 175 2005 at 17,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Tournament Pro 175 2005 tips the scales at 1 385 lbs — 1 258 lbs less than the Alumacraft Navigator 175 CS 2013 at 127 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 Navigator 175 CS 2013 has a 60-hp advantage over the Alumacraft Tournament Pro 175 2005's 90-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.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Navigator 175 CS 2013 is rated for 6 passengers, while the Alumacraft Tournament Pro 175 2005 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Navigator 175 CS 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Navigator 175 CS 2013 comes in at 1 lbs per hp versus 15 lbs per hp for the Alumacraft Tournament Pro 175 2005. 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.
