Both the Lund 1852MT 2010 and the Lund SSV 18 2012 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 1852MT 2010 at 18,0 ft versus Lund SSV 18 2012 at 18,3 ft. At 475 lbs and 460 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 - 45 hp for the Lund 1852MT 2010 and 60 hp for the Lund SSV 18 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 Lund 1852MT 2010 is rated for 6 passengers, while the Lund SSV 18 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1852MT 2010 could be the deciding factor.
Bottom line: Choose the Lund 1852MT 2010 if your priority is putting more people on the water - it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Lund SSV 18 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
