Ranger 191 Cayman 2006 vs Ranger Z20 COMANCHE SERIES 2006 — Same Brand, Different Boat

The Ranger 191 Cayman 2006 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 2006 measures 19,0 feet overall (2006), 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 2006 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 2006 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 2006 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 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Ranger 191 Cayman 2006 vs Ranger Z20 COMANCHE SERIES 2006 — Common Questions

Which is the larger boat — the Ranger 191 Cayman 2006 or the Ranger Z20 COMANCHE SERIES 2006?
The Ranger 191 Cayman 2006 is the longer of the two at 19,0 feet overall. The Ranger Z20 COMANCHE SERIES 2006 comes in at 2,0 feet, making it roughly 17,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Ranger 191 Cayman 2006 or the Ranger Z20 COMANCHE SERIES 2006?
For trailering, the Ranger 191 Cayman 2006 has the edge at 118 lbs dry weight versus 176 lbs for the Ranger Z20 COMANCHE SERIES 2006. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Ranger 191 Cayman 2006 is Coast Guard rated for 5 passengers, while the Ranger Z20 COMANCHE SERIES 2006 is certified for 6. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Ranger Z20 COMANCHE SERIES 2006 measures 95" wide, compared to 93" for the Ranger 191 Cayman 2006. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Ranger 191 Cayman 2006 or the Ranger Z20 COMANCHE SERIES 2006?
The Ranger 191 Cayman 2006 has the bigger tank at 48 gallons, versus 24 gallons on the Ranger Z20 COMANCHE SERIES 2006. That 24-gallon difference translates to roughly 72–120 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Ranger 191 Cayman 2006 and Ranger Z20 COMANCHE SERIES 2006 from the same manufacturer?
Yes — both the Ranger 191 Cayman 2006 and the Ranger Z20 COMANCHE SERIES 2006 are built by Ranger. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
