Starcraft Marine Nexstar 1900 I/O 2006 vs Starcraft Marine STX 206 Viper 2011 — Same Brand, Different Boat

The Starcraft Marine Nexstar 1900 I/O 2006 vs Starcraft Marine STX 206 Viper 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Starcraft Marine Nexstar 1900 I/O 2006 at 19,0 ft versus Starcraft Marine STX 206 Viper 2011 at 20,5 ft. Weight tells a clearer story for trailering families: the Starcraft Marine STX 206 Viper 2011 tips the scales at 1 535 lbs — 1 514 lbs less than the Starcraft Marine Nexstar 1900 I/O 2006 at 21 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 350 hp, the Starcraft Marine Nexstar 1900 I/O 2006 has a 100-hp advantage over the Starcraft Marine STX 206 Viper 2011's 250-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Starcraft Marine Nexstar 1900 I/O 2006 carries 45 gallons versus 5 gallons in the Starcraft Marine STX 206 Viper 2011. 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 Starcraft Marine STX 206 Viper 2011 is rated for 6 passengers, while the Starcraft Marine Nexstar 1900 I/O 2006 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine STX 206 Viper 2011 could be the deciding factor.

Bottom line: Choose the Starcraft Marine STX 206 Viper 2011 if your priority is putting more people on the water — it handles 6 passengers and at 20,5 ft it has the deck room to back that rating up comfortably. The Starcraft Marine Nexstar 1900 I/O 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.

Starcraft Marine Nexstar 1900 I/O 2006 vs Starcraft Marine STX 206 Viper 2011 — Common Questions

Which is the larger boat — the Starcraft Marine Nexstar 1900 I/O 2006 or the Starcraft Marine STX 206 Viper 2011?
The Starcraft Marine STX 206 Viper 2011 is the longer of the two at 20,5 feet overall. The Starcraft Marine Nexstar 1900 I/O 2006 comes in at 19,0 feet, making it roughly 1,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Starcraft Marine Nexstar 1900 I/O 2006 or the Starcraft Marine STX 206 Viper 2011?
For trailering, the Starcraft Marine Nexstar 1900 I/O 2006 has the edge at 21 lbs dry weight versus 1 535 lbs for the Starcraft Marine STX 206 Viper 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Starcraft Marine Nexstar 1900 I/O 2006 is rated to a maximum of 350 hp, giving it the larger power ceiling. The Starcraft Marine STX 206 Viper 2011 tops out at 250 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Starcraft Marine Nexstar 1900 I/O 2006 is Coast Guard rated for 1 passengers, while the Starcraft Marine STX 206 Viper 2011 is certified for 6. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Starcraft Marine Nexstar 1900 I/O 2006 measures 102" wide, compared to 96" for the Starcraft Marine STX 206 Viper 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Starcraft Marine Nexstar 1900 I/O 2006 or the Starcraft Marine STX 206 Viper 2011?
The Starcraft Marine Nexstar 1900 I/O 2006 has the bigger tank at 45 gallons, versus 5 gallons on the Starcraft Marine STX 206 Viper 2011. That 40-gallon difference translates to roughly 120–200 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Starcraft Marine Nexstar 1900 I/O 2006 and Starcraft Marine STX 206 Viper 2011 from the same manufacturer?
Yes — both the Starcraft Marine Nexstar 1900 I/O 2006 and the Starcraft Marine STX 206 Viper 2011 are built by Starcraft Marine. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
