When two boats share the same hull type — in this case both the Blue Wave 190 Super Tunnel 2010 and the Blue Wave 1900 STL 2012 are tunnel designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Blue Wave 190 Super Tunnel 2010 at 18,8 ft versus Blue Wave 1900 STL 2012 at 19,0 ft. Weight tells a clearer story for trailering families: the Blue Wave 1900 STL 2012 tips the scales at 1 395 lbs — 1 384 lbs less than the Blue Wave 190 Super Tunnel 2010 at 11 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.

Both boats share a closely matched power ceiling — 150 hp for the Blue Wave 190 Super Tunnel 2010 and 150 hp for the Blue Wave 1900 STL 2012. 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 190 Super Tunnel 2010 carries 24 gallons versus 3 gallons in the Blue Wave 1900 STL 2012. 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.
