Matching a modified vee Xpress Bayou 18V 2012 against a flat Xpress Tunnel - 1650T 2008 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.
On paper these two are close siblings in the size department — Xpress Bayou 18V 2012 at 18,0 ft versus Xpress Tunnel - 1650T 2008 at 16,0 ft. Weight tells a clearer story for trailering families: the Xpress Tunnel - 1650T 2008 tips the scales at 427 lbs — 352 lbs less than the Xpress Bayou 18V 2012 at 75 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 70 hp, the Xpress Bayou 18V 2012 has a 40-hp advantage over the Xpress Tunnel - 1650T 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 Bayou 18V 2012 is rated for 4 passengers, while the Xpress Tunnel - 1650T 2008 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Xpress Bayou 18V 2012 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Xpress Bayou 18V 2012 comes in at 1 lbs per hp versus 14 lbs per hp for the Xpress Tunnel - 1650T 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.

The Xpress Tunnel - 1650T 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
