When two boats share the same hull type — in this case both the Blue Wave 1900 STL 2012 and the Blue Wave 220 T-Special 2009 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 1900 STL 2012 at 19,0 ft versus Blue Wave 220 T-Special 2009 at 22,0 ft. Weight tells a clearer story for trailering families: the Blue Wave 1900 STL 2012 tips the scales at 1 395 lbs — 1 382 lbs more than the Blue Wave 220 T-Special 2009 at 13 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 1900 STL 2012 and 150 hp for the Blue Wave 220 T-Special 2009. 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 220 T-Special 2009 carries 35 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.

For family outings this is probably the sharpest distinction between the two. The Blue Wave 220 T-Special 2009 is rated for 9 passengers, while the Blue Wave 1900 STL 2012 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Blue Wave 220 T-Special 2009 could be the deciding factor.
