Matching a modified vee Nautic Star 1810 NauticBay 2009 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 1810 NauticBay 2009 at 18,0 ft versus Nautic Star 1900 Sport 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Nautic Star 1810 NauticBay 2009 tips the scales at 1 275 lbs — 1 256 lbs more than the Nautic Star 1900 Sport 2009 at 19 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 Nautic Star 1900 Sport 2009 has a 35-hp advantage over the Nautic Star 1810 NauticBay 2009'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 1810 NauticBay 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nautic Star 1900 Sport 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Nautic Star 1900 Sport 2009 comes in at 0 lbs per hp versus 11 lbs per hp for the Nautic Star 1810 NauticBay 2009. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
