When two boats share the same hull type — in this case both the Ranger 620VS 2013 and the Ranger Z519 Comanche 2013 are modified vee designs with fiberglass 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 — Ranger 620VS 2013 at 20,3 ft versus Ranger Z519 Comanche 2013 at 19,5 ft. Weight tells a clearer story for trailering families: the Ranger 620VS 2013 tips the scales at 2 165 lbs — 540 lbs more than the Ranger Z519 Comanche 2013 at 1 625 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 225 hp, the Ranger 620VS 2013 has a 25-hp advantage over the Ranger Z519 Comanche 2013's 200-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Ranger 620VS 2013 carries 46 gallons versus 2 gallons in the Ranger Z519 Comanche 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 Ranger 620VS 2013 is rated for 6 passengers, while the Ranger Z519 Comanche 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ranger 620VS 2013 could be the deciding factor.
Bottom line: Choose the Ranger 620VS 2013 if your priority is putting more people on the water — it handles 6 passengers and at 20,3 ft it has the deck room to back that rating up comfortably. The Ranger Z519 Comanche 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
