The Xpress Deck Series - 1650D 2008 is a flat-bottom design and the Xpress XP16 2009 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department - Xpress Deck Series - 1650D 2008 at 16,0 ft versus Xpress XP16 2009 at 16,0 ft. Weight tells a clearer story for trailering families: the Xpress XP16 2009 tips the scales at 680 lbs - 270 lbs less than the Xpress Deck Series - 1650D 2008 at 410 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 60 hp, the Xpress XP16 2009 has a 30-hp advantage over the Xpress Deck Series - 1650D 2008's 30-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 Deck Series - 1650D 2008 is rated for 4 passengers, while the Xpress XP16 2009 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Xpress Deck Series - 1650D 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Xpress XP16 2009 comes in at 11 lbs per hp versus 14 lbs per hp for the Xpress Deck Series - 1650D 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.
