Matching a flat Xpress 1440SS 2011 against a modified vee Xpress H18 2009 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Xpress H18 2009 measures 18,0 feet overall (2009), giving it roughly 4,0 additional feet of deck space compared to the Xpress 1440SS 2011 at 14,0 feet (2011). Weight tells a clearer story for trailering families: the Xpress 1440SS 2011 tips the scales at 248 lbs — 119 lbs more than the Xpress H18 2009 at 129 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 2009 has a 135-hp advantage over the Xpress 1440SS 2011's 15-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Xpress H18 2009 is rated for 4 passengers, while the Xpress 1440SS 2011 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Xpress H18 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Xpress H18 2009 comes in at 1 lbs per hp versus 17 lbs per hp for the Xpress 1440SS 2011. 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: Choose the Xpress H18 2009 if your priority is putting more people on the water — it handles 4 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Xpress 1440SS 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
