Both the Lund A 12 2005 and the Lund WC 14 DLX 2010 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 A 12 2005 at 12,0 ft versus Lund WC 14 DLX 2010 at 14,5 ft. Weight tells a clearer story for trailering families: the Lund WC 14 DLX 2010 tips the scales at 390 lbs - 225 lbs less than the Lund A 12 2005 at 165 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 - 10 hp for the Lund A 12 2005 and 25 hp for the Lund WC 14 DLX 2010. 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 Lund WC 14 DLX 2010 is rated for 4 passengers, while the Lund A 12 2005 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund WC 14 DLX 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Lund WC 14 DLX 2010 comes in at 16 lbs per hp versus 17 lbs per hp for the Lund A 12 2005. 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 WC 14 DLX 2010 if your priority is putting more people on the water - it handles 4 passengers and at 14,5 ft it has the deck room to back that rating up comfortably. The Lund A 12 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
