Matching a tunnel Alumacraft All-Weld MV 2072 AW Tunnel FF 2011 against a deep vee Alumacraft Navigator 175 Sport 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.
Size is the most obvious dividing line here. The Alumacraft Navigator 175 Sport 2011 measures 17,7 feet overall (2011), giving it roughly 15,7 additional feet of deck space compared to the Alumacraft All-Weld MV 2072 AW Tunnel FF 2011 at 2,0 feet (2011). Weight tells a clearer story for trailering families: the Alumacraft Navigator 175 Sport 2011 tips the scales at 1 357 lbs — 1 345 lbs less than the Alumacraft All-Weld MV 2072 AW Tunnel FF 2011 at 12 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.
Both boats share a closely matched power ceiling — 130 hp for the Alumacraft All-Weld MV 2072 AW Tunnel FF 2011 and 150 hp for the Alumacraft Navigator 175 Sport 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Alumacraft Navigator 175 Sport 2011 carries 38 gallons versus 21 gallons in the Alumacraft All-Weld MV 2072 AW Tunnel FF 2011. 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 Tunnel FF 2011 is rated for 8 passengers, while the Alumacraft Navigator 175 Sport 2011 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 Tunnel FF 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft All-Weld MV 2072 AW Tunnel FF 2011 comes in at 0 lbs per hp versus 9 lbs per hp for the Alumacraft Navigator 175 Sport 2011. 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.
Bottom line: Choose the Alumacraft All-Weld MV 2072 AW Tunnel FF 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 Sport 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
