The Blue Wave 1900 STL 2009 is a tunnel hull design and the Blue Wave 1902 Evolution 2010 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 - Blue Wave 1900 STL 2009 at 19,0 ft versus Blue Wave 1902 Evolution 2010 at 19,2 ft. At 1 395 lbs and 1 305 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 1900 STL 2009 and 150 hp for the Blue Wave 1902 Evolution 2010. 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. Fuel capacity breaks the other way: the Blue Wave 1902 Evolution 2010 carries 37 gallons versus 30 gallons in the Blue Wave 1900 STL 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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.
