Both the Xpress H18 2008 and the Xpress H20 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 H18 2008 at 18,0 ft versus Xpress H20 2013 at 20,3 ft. Weight tells a clearer story for trailering families: the Xpress H20 2013 tips the scales at 1 470 lbs - 176 lbs less than the Xpress H18 2008 at 1 294 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 150 hp, the Xpress H18 2008 has a 35-hp advantage over the Xpress H20 2013's 115-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
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.
Bottom line: The Xpress H20 2013 at 20,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Xpress H18 2008 at 18,0 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
