The Ranger 191 Cayman 2007 vs Ranger Z20 COMANCHE SERIES 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Ranger 191 Cayman 2007 measures 19,0 feet overall (2007), giving it roughly 17,0 additional feet of deck space compared to the Ranger Z20 COMANCHE SERIES 2006 at 2,0 feet (2006). At 118 lbs and 176 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.
Both boats share a closely matched power ceiling — 200 hp for the Ranger 191 Cayman 2007 and 200 hp for the Ranger Z20 COMANCHE SERIES 2006. 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. Fuel capacity breaks the other way: the Ranger 191 Cayman 2007 carries 48 gallons versus 24 gallons in the Ranger Z20 COMANCHE SERIES 2006. 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 Z20 COMANCHE SERIES 2006 is rated for 6 passengers, while the Ranger 191 Cayman 2007 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 SERIES 2006 could be the deciding factor.
Bottom line: Choose the Ranger Z20 COMANCHE SERIES 2006 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 191 Cayman 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
