Matching a deep vee Alumacraft Navigator 165 Sport 2012 against a modified vee Alumacraft Navigator 175 CS 2007 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 165 Sport 2012 at 16,7 ft versus Alumacraft Navigator 175 CS 2007 at 17,0 ft. At 105 lbs and 127 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 175 CS 2007 has a 60-hp advantage over the Alumacraft Navigator 165 Sport 2012's 90-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 Navigator 165 Sport 2012 carries 19 gallons versus 4 gallons in the Alumacraft Navigator 175 CS 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Navigator 165 Sport 2012 is rated for 6 passengers, while the Alumacraft Navigator 175 CS 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 Navigator 165 Sport 2012 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Navigator 175 CS 2007 comes in at 1 lbs per hp versus 1 lbs per hp for the Alumacraft Navigator 165 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.
