When two boats share the same hull type — in this case both the Weldcraft Marine 21 Legacy 2013 and the Weldcraft Marine 24 Select 2012 are modified vee designs with aluminum construction — 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 — Weldcraft Marine 21 Legacy 2013 at 21,0 ft versus Weldcraft Marine 24 Select 2012 at 24,0 ft. At 31 lbs and 38 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.
The Weldcraft Marine 24 Select 2012 tops out at 4 hp. Engine specs for the Weldcraft Marine 21 Legacy 2013 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Weldcraft Marine 24 Select 2012 carries 93 gallons versus 62 gallons in the Weldcraft Marine 21 Legacy 2013. 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 Weldcraft Marine 24 Select 2012 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 24 Select 2012 could be the deciding factor.
Bottom line: Choose the Weldcraft Marine 24 Select 2012 if your priority is putting more people on the water — it handles 7 passengers and at 24,0 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.
