The Alumacraft All-Weld MV 2072 AW SC 2011 vs Alumacraft Navigator 175 2004 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.
The power gap is worth calling out. Rated to 115 hp, the Alumacraft All-Weld MV 2072 AW SC 2011 has a 35-hp advantage over the Alumacraft Navigator 175 2004's 80-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 All-Weld MV 2072 AW SC 2011 carries 21 gallons versus 4 gallons in the Alumacraft Navigator 175 2004. 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 All-Weld MV 2072 AW SC 2011 is rated for 8 passengers, while the Alumacraft Navigator 175 2004 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft All-Weld MV 2072 AW SC 2011 could be the deciding factor.
Bottom line: Choose the Alumacraft All-Weld MV 2072 AW SC 2011 if your priority is putting more people on the water — it handles 8 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Alumacraft Navigator 175 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
