The Xpress Deck Series - 1650D 2008 is a flat-bottom design and the Xpress Xclusive Bay Series - X24Bay 2008 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.
Size is the most obvious dividing line here. The Xpress Xclusive Bay Series - X24Bay 2008 measures 24,0 feet overall (2008), giving it roughly 8,0 additional feet of deck space compared to the Xpress Deck Series - 1650D 2008 at 16,0 feet (2008). Weight tells a clearer story for trailering families: the Xpress Xclusive Bay Series - X24Bay 2008 tips the scales at 1 720 lbs - 1 310 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 250 hp, the Xpress Xclusive Bay Series - X24Bay 2008 has a 220-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 Xclusive Bay Series - X24Bay 2008 is rated for 6 passengers, while the Xpress Deck Series - 1650D 2008 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Xpress Xclusive Bay Series - X24Bay 2008 could be the deciding factor.
Bottom line: Choose the Xpress Xclusive Bay Series - X24Bay 2008 if your priority is putting more people on the water - it handles 6 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Xpress Deck Series - 1650D 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
