The Blue Wave 190 Classic DC 2008 is a modified-V design and the Blue Wave 190 Super Tunnel 2011 is a tunnel hull 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 - Blue Wave 190 Classic DC 2008 at 18,0 ft versus Blue Wave 190 Super Tunnel 2011 at 18,8 ft. At 1 100 lbs and 1 100 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling - 150 hp for the Blue Wave 190 Classic DC 2008 and 150 hp for the Blue Wave 190 Super Tunnel 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads - 24 gal and 24 gal - so range won't be a tiebreaker here.
Both boats are rated for 7 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 Blue Wave 190 Classic DC 2008 and Blue Wave 190 Super Tunnel 2011 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
