When two boats share the same hull type — in this case both the Ranger Z21I Intracoastal 2013 and the Ranger Z520 Comanche 2011 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 Z21I Intracoastal 2013 at 21,2 ft versus Ranger Z520 Comanche 2011 at 20,8 ft. At 1 875 lbs and 1 825 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.

The power gap is worth calling out. Rated to 225 hp, the Ranger Z21I Intracoastal 2013 has a 25-hp advantage over the Ranger Z520 Comanche 2011's 200-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 24 gal and 26 gal — so range won't be a tiebreaker here.

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.
