Matching a modified vee Blue Wave 160 V-Bay 2010 against a tunnel Blue Wave 1900 STL 2009 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 — Blue Wave 160 V-Bay 2010 at 16,0 ft versus Blue Wave 1900 STL 2009 at 19,0 ft. Weight tells a clearer story for trailering families: the Blue Wave 1900 STL 2009 tips the scales at 1 395 lbs — 600 lbs less than the Blue Wave 160 V-Bay 2010 at 795 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 150 hp, the Blue Wave 1900 STL 2009 has a 75-hp advantage over the Blue Wave 160 V-Bay 2010's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Blue Wave 160 V-Bay 2010 carries 18 gallons versus 3 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.
For family outings this is probably the sharpest distinction between the two. The Blue Wave 1900 STL 2009 is rated for 7 passengers, while the Blue Wave 160 V-Bay 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Blue Wave 1900 STL 2009 could be the deciding factor.
Bottom line: Choose the Blue Wave 1900 STL 2009 if your priority is putting more people on the water — it handles 7 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Blue Wave 160 V-Bay 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
