Ranger 178VS 2006 vs Ranger Z Comanche Series - Z20 2007 — Same Brand, Different Boat

The Ranger 178VS 2006 vs Ranger Z Comanche Series - Z20 2007 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 178VS 2006 measures 17,0 feet overall (2006), giving it roughly 15,0 additional feet of deck space compared to the Ranger Z Comanche Series - Z20 2007 at 2,0 feet (2007). Weight tells a clearer story for trailering families: the Ranger Z Comanche Series - Z20 2007 tips the scales at 1 735 lbs — 250 lbs less than the Ranger 178VS 2006 at 1 485 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 Z Comanche Series - Z20 2007 has a 110-hp advantage over the Ranger 178VS 2006's 115-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 Z Comanche Series - Z20 2007 carries 48 gallons versus 25 gallons in the Ranger 178VS 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 Z Comanche Series - Z20 2007 is rated for 6 passengers, while the Ranger 178VS 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 Z Comanche Series - Z20 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Ranger Z Comanche Series - Z20 2007 comes in at 8 lbs per hp versus 13 lbs per hp for the Ranger 178VS 2006. 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: Choose the Ranger Z Comanche Series - Z20 2007 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 178VS 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.

Which is easier to trailer — the Ranger 178VS 2006 or the Ranger Z Comanche Series - Z20 2007?
For trailering, the Ranger 178VS 2006 has the edge at 1 485 lbs dry weight versus 1 735 lbs for the Ranger Z Comanche Series - Z20 2007. 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 Z Comanche Series - Z20 2007 is rated to a maximum of 225 hp, giving it the larger power ceiling. The Ranger 178VS 2006 tops out at 115 hp.

How many people can each boat hold?
The Ranger 178VS 2006 is Coast Guard rated for 5 passengers, while the Ranger Z Comanche Series - Z20 2007 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.

The Ranger Z Comanche Series - Z20 2007 has a better power-to-weight ratio at 8 lbs per hp compared to 13 lbs per hp for the Ranger 178VS 2006. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
