When two boats share the same hull type — in this case both the Weldcraft Marine 18 Renegade 2013 and the Weldcraft Marine 20 Renegade 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?
Size is the most obvious dividing line here. The Weldcraft Marine 18 Renegade 2013 measures 18,1 feet overall (2013), giving it roughly 16,1 additional feet of deck space compared to the Weldcraft Marine 20 Renegade 2012 at 2,0 feet (2012). At 24 lbs and 25 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 20 Renegade 2012 tops out at 225 hp. Engine specs for the Weldcraft Marine 18 Renegade 2013 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Weldcraft Marine 20 Renegade 2012 carries 62 gallons versus 42 gallons in the Weldcraft Marine 18 Renegade 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Weldcraft Marine 18 Renegade 2013 at 18,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Weldcraft Marine 20 Renegade 2012 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
