The Lund 1436L 2010 is a flat-bottom design and the Lund WD 14 2011 is a modified-V design, so you're likely deciding between two noticeably 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 - Lund 1436L 2010 at 14,0 ft versus Lund WD 14 2011 at 14,5 ft. At 145 lbs and 240 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 - 15 hp for the Lund 1436L 2010 and 25 hp for the Lund WD 14 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.
For family outings this is probably the sharpest distinction between the two. The Lund WD 14 2011 is rated for 4 passengers, while the Lund 1436L 2010 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund WD 14 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Lund WD 14 2011 comes in at 10 lbs per hp versus 10 lbs per hp for the Lund 1436L 2010. 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 WD 14 2011 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 1436L 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
