Both the Xpress H51 2009 and the Xpress XP16CC 2013 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 H51 2009 at 17,0 ft versus Xpress XP16CC 2013 at 16,0 ft. Weight tells a clearer story for trailering families: the Xpress H51 2009 tips the scales at 905 lbs - 213 lbs more than the Xpress XP16CC 2013 at 692 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.

The power gap is worth calling out. Rated to 115 hp, the Xpress H51 2009 has a 55-hp advantage over the Xpress XP16CC 2013's 60-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 18 gal and 18 gal - so range won't be a tiebreaker here.

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 H51 2009 comes in at 8 lbs per hp versus 12 lbs per hp for the Xpress XP16CC 2013. 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.
