When two boats share the same hull type — in this case both the Ranger Z20 Comanche 2010 and the Ranger Z21 Intracoastal 2012 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?

On paper these two are close siblings in the size department — Ranger Z20 Comanche 2010 at 20,4 ft versus Ranger Z21 Intracoastal 2012 at 21,2 ft. Weight tells a clearer story for trailering families: the Ranger Z21 Intracoastal 2012 tips the scales at 1 875 lbs — 140 lbs less than the Ranger Z20 Comanche 2010 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.

Both boats share a closely matched power ceiling — 225 hp for the Ranger Z20 Comanche 2010 and 225 hp for the Ranger Z21 Intracoastal 2012. 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 Z20 Comanche 2010 carries 48 gallons versus 24 gallons in the Ranger Z21 Intracoastal 2012. 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.
