The Lund SSV 18 2012 is a modified-V design and the Lund WC 12 2013 is a deep-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.
Size is the most obvious dividing line here. The Lund SSV 18 2012 measures 18,3 feet overall (2012), giving it roughly 6,2 additional feet of deck space compared to the Lund WC 12 2013 at 12,2 feet (2013). Weight tells a clearer story for trailering families: the Lund SSV 18 2012 tips the scales at 460 lbs - 255 lbs more than the Lund WC 12 2013 at 205 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 60 hp, the Lund SSV 18 2012 has a 45-hp advantage over the Lund WC 12 2013's 15-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 SSV 18 2012 is rated for 5 passengers, while the Lund WC 12 2013 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund SSV 18 2012 could be the deciding factor.
Bottom line: Choose the Lund SSV 18 2012 if your priority is putting more people on the water - it handles 5 passengers and at 18,3 ft it has the deck room to back that rating up comfortably. The Lund WC 12 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
