Matching a flat Lund 1648M Jon 2012 against a modified vee Lund 1950 Tyee Gran Sport 2006 means you're likely deciding between two genuinely 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 1950 Tyee Gran Sport 2006 measures 19,0 feet overall (2006), giving it roughly 3,2 additional feet of deck space compared to the Lund 1648M Jon 2012 at 15,8 feet (2012). Weight tells a clearer story for trailering families: the Lund 1950 Tyee Gran Sport 2006 tips the scales at 1 875 lbs — 1 833 lbs less than the Lund 1648M Jon 2012 at 42 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 225 hp, the Lund 1950 Tyee Gran Sport 2006 has a 190-hp advantage over the Lund 1648M Jon 2012's 35-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 1950 Tyee Gran Sport 2006 is rated for 9 passengers, while the Lund 1648M Jon 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1950 Tyee Gran Sport 2006 could be the deciding factor.
Bottom line: Choose the Lund 1950 Tyee Gran Sport 2006 if your priority is putting more people on the water — it handles 9 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Lund 1648M Jon 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
