Both the Chaparral 180 SSi Sportboat 2006 and the Chaparral 280 SSi Sportboat 2004 are modified-V designs, so 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?

The power gap is worth calling out. Rated to 320 hp, the Chaparral 280 SSi Sportboat 2004 has a 65-hp advantage over the Chaparral 180 SSi Sportboat 2006's 255-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Chaparral 280 SSi Sportboat 2004 carries 143 gallons versus 23 gallons in the Chaparral 180 SSi Sportboat 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 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.
