Both the Lund 1648M 2008 and the Lund A 12 2011 are modified-V designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department - Lund 1648M 2008 at 15,0 ft versus Lund A 12 2011 at 12,1 ft. Weight tells a clearer story for trailering families: the Lund 1648M 2008 tips the scales at 420 lbs - 256 lbs more than the Lund A 12 2011 at 164 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 35 hp, the Lund 1648M 2008 has a 25-hp advantage over the Lund A 12 2011's 10-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Lund 1648M 2008 is rated for 4 passengers, while the Lund A 12 2011 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1648M 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Lund 1648M 2008 comes in at 12 lbs per hp versus 16 lbs per hp for the Lund A 12 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 Lund 1648M 2008 if your priority is putting more people on the water - it handles 4 passengers and at 15,0 ft it has the deck room to back that rating up comfortably. The Lund A 12 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
