The outboard versions are the same length, 23' 6", and both have an 8' 6" beam and room for 13 people. The Sea Ray SDX 230 Outboard holds 60 gallons and takes a Mercury 200 hp FourStroke or 250 hp Verado. The Chaparral 23 SSi OB holds 56 gallons and is rated for up to 250 hp.
Both builders use a forward-facing drive on their 23-foot surf boats.

Chaparral's specification page lists no ballast figure. Buyers who want a dedicated inboard wake boat can compare these with the boats in the wake boat buying guide.
In the 26-to-28-foot luxury class, the Sea Rays hold more fuel and the Chaparrals have a slightly steeper deadrise. The Sea Ray SLX 260 is 25' 9" long with an 8' 6" beam, a 21-degree deadrise, 75 gallons of fuel and room for 15 people, with a 350 hp MerCruiser 6.2L.

Above 30 feet, both builders sell twin-outboard luxury boats, and the fuel advantage switches between sizes. The Sea Ray SLX 280 Outboard is 31' 5" long with a 9' beam and 135 gallons of fuel, and it comes standard with twin Mercury 250 hp Verado outboards with joystick piloting. The Chaparral 280 OSX is 30' 6" long with a 9' beam and 123 gallons of fuel, and it is rated for up to 500 hp.

The Chaparral 310 OSX is 32' 6" long with a 9' 6" beam and 182 gallons of fuel, and it is rated for up to 600 hp. Chaparral lists the 280 OSX, 310 OSX, SSX 6, SSX 8 and SSX 30 as Yacht Certified rather than giving a person count.
Engine choice is the clearest difference between the two builders. Every engine on the Sea Ray model pages read for this article is a Mercury outboard or a Mercury MerCruiser. Chaparral's option lists for the 21 SSi, 23 SSi and SSX 6 include both Mercury and Volvo engines, and its GTS 3 page names Volvo or MerCruiser forward drives. On its outboard models, Chaparral lists Yamaha as well as Mercury outboards: the 21 SSi OB offers Yamaha 150 hp and 200 hp four-strokes, and the 280 OSX offers twin Yamaha 200 hp or 250 hp outboards. A buyer who already has a Volvo, Yamaha or Mercury service dealer nearby may want to start there. For how outboards, sterndrives and inboards compare, see inboard vs outboard vs sterndrive.
Both builders offer a five-year warranty and a lifetime limited hull warranty on these boats. Sea Ray's warranty page says its SURPA5S+ warranty "provides five years of bow-to-stern factory warranty on the boat and its components" on SPX, SDX and SLX sport boats, excluding the SLX 400 and SLX 400 Outboard, along with a Limited Lifetime Structural Hull / Deck Warranty to the original owner. Chaparral's US home page says "All 2027 Chaparral models come with a Lifetime Limited Hull Warranty and 5-Year Premium limited component warranty - standard." Read both warranties in full, including what each covers and who it transfers to, before you buy.
