Ranger Z20 COMANCHE SERIES 2006 vs Ranger Z520 Comanche 2008 — Same Brand, Different Boat

The Ranger Z20 COMANCHE SERIES 2006 vs Ranger Z520 Comanche 2008 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.

On paper these two are close siblings in the size department — Ranger Z20 COMANCHE SERIES 2006 at 2,0 ft versus Ranger Z520 Comanche 2008 at 2,0 ft. Weight tells a clearer story for trailering families: the Ranger Z520 Comanche 2008 tips the scales at 1 825 lbs — 1 649 lbs less than the Ranger Z20 COMANCHE SERIES 2006 at 176 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 250 hp, the Ranger Z520 Comanche 2008 has a 50-hp advantage over the Ranger Z20 COMANCHE SERIES 2006'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 Z520 Comanche 2008 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.

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.

At this size, power-to-weight ratio matters more than outright horsepower. The Ranger Z20 COMANCHE SERIES 2006 comes in at 1 lbs per hp versus 7 lbs per hp for the Ranger Z520 Comanche 2008. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Performance buyers should lean toward the Ranger Z520 Comanche 2008 and its 250-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Ranger Z20 COMANCHE SERIES 2006 with its 200-hp rating is the more economical daily driver.

Ranger Z20 COMANCHE SERIES 2006 vs Ranger Z520 Comanche 2008 — Common Questions

Which is the larger boat — the Ranger Z20 COMANCHE SERIES 2006 or the Ranger Z520 Comanche 2008?
The Ranger Z520 Comanche 2008 is the longer of the two at 2,0 feet overall. The Ranger Z20 COMANCHE SERIES 2006 comes in at 2,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Ranger Z20 COMANCHE SERIES 2006 or the Ranger Z520 Comanche 2008?
For trailering, the Ranger Z20 COMANCHE SERIES 2006 has the edge at 176 lbs dry weight versus 1 825 lbs for the Ranger Z520 Comanche 2008. 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.
Which boat can handle a bigger outboard?
The Ranger Z520 Comanche 2008 is rated to a maximum of 250 hp, giving it the larger power ceiling. The Ranger Z20 COMANCHE SERIES 2006 tops out at 200 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Ranger Z20 COMANCHE SERIES 2006 is Coast Guard rated for 6 passengers, while the Ranger Z520 Comanche 2008 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 has the better power-to-weight ratio?
The Ranger Z20 COMANCHE SERIES 2006 has a better power-to-weight ratio at 1 lbs per hp compared to 7 lbs per hp for the Ranger Z520 Comanche 2008. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Ranger Z20 COMANCHE SERIES 2006 and Ranger Z520 Comanche 2008 share an 95 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Ranger Z20 COMANCHE SERIES 2006 or the Ranger Z520 Comanche 2008?
The Ranger Z520 Comanche 2008 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 Z20 COMANCHE SERIES 2006 and Ranger Z520 Comanche 2008 from the same manufacturer?
Yes — both the Ranger Z20 COMANCHE SERIES 2006 and the Ranger Z520 Comanche 2008 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.
