When two boats share the same hull type — in this case both the Weldcraft Marine 18 Renegade SJ 2012 and the Weldcraft Marine 18 Renegade SJ 2013 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 18 Renegade SJ 2012 at 18,1 ft versus Weldcraft Marine 18 Renegade SJ 2013 at 18,1 ft. Weight tells a clearer story for trailering families: the Weldcraft Marine 18 Renegade SJ 2012 tips the scales at 205 lbs — 181 lbs more than the Weldcraft Marine 18 Renegade SJ 2013 at 24 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 Weldcraft Marine 18 Renegade SJ 2012 carries a rated maximum of 225 hp. Engine data for the Weldcraft Marine 18 Renegade SJ 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 42 gal and 42 gal — so range won't be a tiebreaker here.

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.
