When two boats share the same hull type — in this case both the Ranger Z20 Comanche 2009 and the Ranger Z21 Intracoastal 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 Z21 Intracoastal 2009 measures 21,0 feet overall (2009), giving it roughly 19,0 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 Z21 Intracoastal 2009 tips the scales at 1 875 lbs — 140 lbs less 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.
The power gap is worth calling out. Rated to 250 hp, the Ranger Z21 Intracoastal 2009 has a 25-hp advantage over the Ranger Z20 Comanche 2009's 225-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 Z20 Comanche 2009 carries 48 gallons versus 24 gallons in the Ranger Z21 Intracoastal 2009. 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.
Bottom line: The Ranger Z21 Intracoastal 2009 at 21,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Ranger Z20 Comanche 2009 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
