When two boats share the same hull type — in this case both the Malibu Sunsetter 21 XTi 2005 and the Malibu Sunsetter 21 XTi 2006 are modified vee designs with composite 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 — Malibu Sunsetter 21 XTi 2005 at 21,0 ft versus Malibu Sunsetter 21 XTi 2006 at 21,0 ft. At 33 lbs and 33 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.

Both boats share a closely matched power ceiling — 400 hp for the Malibu Sunsetter 21 XTi 2005 and 400 hp for the Malibu Sunsetter 21 XTi 2006. 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. Both carry nearly identical fuel loads — 46 gal and 46 gal — so range won't be a tiebreaker here.

Both boats are rated for 12 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.
