When two boats share the same hull type — in this case both the Alumacraft Navigator 175 Sport 2007 and the Alumacraft Tournament Pro 195 CS 2007 are modified 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 Navigator 175 Sport 2007 at 17,0 ft versus Alumacraft Tournament Pro 195 CS 2007 at 19,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Tournament Pro 195 CS 2007 tips the scales at 1 695 lbs — 338 lbs less than the Alumacraft Navigator 175 Sport 2007 at 1 357 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 200 hp, the Alumacraft Tournament Pro 195 CS 2007 has a 50-hp advantage over the Alumacraft Navigator 175 Sport 2007'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 — 4 gal and 4 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Tournament Pro 195 CS 2007 is rated for 6 passengers, while the Alumacraft Navigator 175 Sport 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Tournament Pro 195 CS 2007 could be the deciding factor.
