The Chaparral 180 SSi Sportboat 2004 is a modified-V design and the Chaparral 204 Xtreme 2011 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Both boats share a closely matched power ceiling - 255 hp for the Chaparral 180 SSi Sportboat 2004 and 270 hp for the Chaparral 204 Xtreme 2011. 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 Chaparral 204 Xtreme 2011 carries 35 gallons versus 21 gallons in the Chaparral 180 SSi Sportboat 2004. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Chaparral 204 Xtreme 2011 is rated for 10 passengers, while the Chaparral 180 SSi Sportboat 2004 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Chaparral 204 Xtreme 2011 could be the deciding factor.
