Both the Xpress HD16DB 2013 and the Xpress SV Utility Series - SV17SC 2008 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 HD16DB 2013 at 16,0 ft versus Xpress SV Utility Series - SV17SC 2008 at 17,0 ft. Weight tells a clearer story for trailering families: the Xpress SV Utility Series - SV17SC 2008 tips the scales at 920 lbs - 320 lbs less than the Xpress HD16DB 2013 at 600 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 - 50 hp for the Xpress HD16DB 2013 and 70 hp for the Xpress SV Utility Series - SV17SC 2008. 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 HD16DB 2013 comes in at 12 lbs per hp versus 13 lbs per hp for the Xpress SV Utility Series - SV17SC 2008. 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.
Bottom line: Performance buyers should lean toward the Xpress SV Utility Series - SV17SC 2008 and its 70-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Xpress HD16DB 2013 with its 50-hp rating is the more economical daily driver.
