Matching a modified vee Weldcraft Marine 21 Legacy 2013 against a deep vee Weldcraft Marine 256 2011 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 Weldcraft Marine 256 2011 measures 25,2 feet overall (2011), giving it roughly 4,2 additional feet of deck space compared to the Weldcraft Marine 21 Legacy 2013 at 21,0 feet (2013). Weight tells a clearer story for trailering families: the Weldcraft Marine 256 2011 tips the scales at 2 225 lbs — 2 194 lbs less than the Weldcraft Marine 21 Legacy 2013 at 31 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.
For family outings this is probably the sharpest distinction between the two. The Weldcraft Marine 256 2011 is rated for 7 passengers, while the Weldcraft Marine 21 Legacy 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Weldcraft Marine 256 2011 could be the deciding factor.
Bottom line: Choose the Weldcraft Marine 256 2011 if your priority is putting more people on the water — it handles 7 passengers and at 25,2 ft it has the deck room to back that rating up comfortably. The Weldcraft Marine 21 Legacy 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
