When two boats share the same hull type — in this case both the Ranger 619VS 2010 and the Ranger Z20 Comanche 2009 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?
Size is the most obvious dividing line here. The Ranger 619VS 2010 measures 19,5 feet overall (2010), giving it roughly 17,5 additional feet of deck space compared to the Ranger Z20 Comanche 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Ranger 619VS 2010 tips the scales at 1 975 lbs — 240 lbs more than the Ranger Z20 Comanche 2009 at 1 735 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.
Both boats share a closely matched power ceiling — 225 hp for the Ranger 619VS 2010 and 225 hp for the Ranger Z20 Comanche 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 45 gal and 48 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Ranger Z20 Comanche 2009 is rated for 6 passengers, while the Ranger 619VS 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ranger Z20 Comanche 2009 could be the deciding factor.
Bottom line: Choose the Ranger Z20 Comanche 2009 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Ranger 619VS 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
