When two boats share the same hull type — in this case both the Chaparral 275 SSi Sportboat 2007 and the Chaparral 287 SSX 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 — Chaparral 275 SSi Sportboat 2007 at 28,0 ft versus Chaparral 287 SSX 2012 at 28,8 ft. At 73 lbs and 68 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 525 hp, the Chaparral 275 SSi Sportboat 2007 has a 95-hp advantage over the Chaparral 287 SSX 2012's 430-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 105 gal and 105 gal — so range won't be a tiebreaker here.
