Matching a modified vee Nautic Star 190 RG NauticBay 2010 against a deep vee Nautic Star 1900 Sport 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 — Nautic Star 190 RG NauticBay 2010 at 18,7 ft versus Nautic Star 1900 Sport 2009 at 18,0 ft.

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 Nautic Star 1900 Sport 2009 has a 35-hp advantage over the Nautic Star 190 RG NauticBay 2010's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Nautic Star 1900 Sport 2009 carries 66 gallons versus 35 gallons in the Nautic Star 190 RG NauticBay 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Nautic Star 190 RG NauticBay 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
