Matching a deep vee Alumacraft Navigator 165 CS 2010 against a flat Alumacraft Riveted Jon 1648 NCS 2011 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 CS 2010 at 16,7 ft versus Alumacraft Riveted Jon 1648 NCS 2011 at 16,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Navigator 165 CS 2010 tips the scales at 965 lbs — 939 lbs more than the Alumacraft Riveted Jon 1648 NCS 2011 at 26 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 90 hp, the Alumacraft Navigator 165 CS 2010 has a 60-hp advantage over the Alumacraft Riveted Jon 1648 NCS 2011's 30-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

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 Riveted Jon 1648 NCS 2011 comes in at 1 lbs per hp versus 11 lbs per hp for the Alumacraft Navigator 165 CS 2010. 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.
