Alumacraft 1648 NCS 2001 vs Alumacraft Navigator 175 CS 2011 - Boat Spec Comparison

Q: Which is easier to trailer — the Alumacraft 1648 NCS 2001 or the Alumacraft Navigator 175 CS 2011?

For trailering, the Alumacraft 1648 NCS 2001 has the edge at 26 lbs dry weight versus 127 lbs for the Alumacraft Navigator 175 CS 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

Q: What is the maximum horsepower rating for these boats?

The Alumacraft Navigator 175 CS 2011 has a documented max rating of 150 hp. Engine specifications for the Alumacraft 1648 NCS 2001 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.

Q: How many people can each boat hold?

The Alumacraft 1648 NCS 2001 is Coast Guard rated for 5 passengers, while the Alumacraft Navigator 175 CS 2011 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

Q: Which boat is wider, and does it affect trailering?

The Alumacraft Navigator 175 CS 2011 measures 95" wide, compared to 7" for the Alumacraft 1648 NCS 2001. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

Q: Are the Alumacraft 1648 NCS 2001 and Alumacraft Navigator 175 CS 2011 from the same manufacturer?

Yes — both the Alumacraft 1648 NCS 2001 and the Alumacraft Navigator 175 CS 2011 are built by Alumacraft. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

The Alumacraft 1648 NCS 2001 vs Alumacraft Navigator 175 CS 2011 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.
