Matching a flat Alumacraft 1648 NCS 2009 against a modified vee Alumacraft All Weld MV 1546 DD 2012 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 1648 NCS 2009 at 16,0 ft versus Alumacraft All Weld MV 1546 DD 2012 at 15,0 ft. At 26 lbs and 34 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.
Both boats share a closely matched power ceiling — 35 hp for the Alumacraft 1648 NCS 2009 and 25 hp for the Alumacraft All Weld MV 1546 DD 2012. 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.
For family outings this is probably the sharpest distinction between the two. The Alumacraft 1648 NCS 2009 is rated for 5 passengers, while the Alumacraft All Weld MV 1546 DD 2012 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft 1648 NCS 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft 1648 NCS 2009 comes in at 1 lbs per hp versus 1 lbs per hp for the Alumacraft All Weld MV 1546 DD 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.
Bottom line: Choose the Alumacraft 1648 NCS 2009 if your priority is putting more people on the water — it handles 5 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Alumacraft All Weld MV 1546 DD 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
