Both the Xpress SV Utility Series - SV18CC 2008 and the Xpress XP17 2010 are modified-V designs, both built in aluminium, 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?

On paper these two are close siblings in the size department - Xpress SV Utility Series - SV18CC 2008 at 18,0 ft versus Xpress XP17 2010 at 17,0 ft. Weight tells a clearer story for trailering families: the Xpress SV Utility Series - SV18CC 2008 tips the scales at 1 045 lbs - 125 lbs more than the Xpress XP17 2010 at 920 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling - 90 hp for the Xpress SV Utility Series - SV18CC 2008 and 70 hp for the Xpress XP17 2010. 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 boats are rated for 4 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Xpress SV Utility Series - SV18CC 2008 comes in at 12 lbs per hp versus 13 lbs per hp for the Xpress XP17 2010. The lower the ratio the more explosive the acceleration - meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
