The Larson FX 2050 DC O/B 2013 is a deep-V design and the Larson LX 620 SF 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.

Size is the most obvious dividing line here. The Larson FX 2050 DC O/B 2013 measures 20,2 feet overall (2013), giving it roughly 4,0 additional feet of deck space compared to the Larson LX 620 SF 2011 at 16,2 feet (2011). Weight tells a clearer story for trailering families: the Larson FX 2050 DC O/B 2013 tips the scales at 2 768 lbs - 1 618 lbs more than the Larson LX 620 SF 2011 at 1 150 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 250 hp, the Larson FX 2050 DC O/B 2013 has a 160-hp advantage over the Larson LX 620 SF 2011's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Larson FX 2050 DC O/B 2013 carries 35 gallons versus 23 gallons in the Larson LX 620 SF 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Larson FX 2050 DC O/B 2013 is rated for 7 passengers, while the Larson LX 620 SF 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson FX 2050 DC O/B 2013 could be the deciding factor.
