Starcraft Marine Starfire 1600 SC 2007 vs Starcraft Marine STX 186 Viper 2013 — Same Brand, Different Boat

The Starcraft Marine Starfire 1600 SC 2007 vs Starcraft Marine STX 186 Viper 2013 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.

Size is the most obvious dividing line here. The Starcraft Marine STX 186 Viper 2013 measures 18,5 feet overall (2013), giving it roughly 3,5 additional feet of deck space compared to the Starcraft Marine Starfire 1600 SC 2007 at 15,0 feet (2007). Weight tells a clearer story for trailering families: the Starcraft Marine STX 186 Viper 2013 tips the scales at 1 763 lbs — 958 lbs less than the Starcraft Marine Starfire 1600 SC 2007 at 805 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 175 hp, the Starcraft Marine STX 186 Viper 2013 has a 115-hp advantage over the Starcraft Marine Starfire 1600 SC 2007's 60-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 STX 186 Viper 2013 carries 43 gallons versus 13 gallons in the Starcraft Marine Starfire 1600 SC 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Starcraft Marine STX 186 Viper 2013 at 18,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Starcraft Marine Starfire 1600 SC 2007 at 15,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Starcraft Marine Starfire 1600 SC 2007 vs Starcraft Marine STX 186 Viper 2013 — Common Questions

Which is the larger boat — the Starcraft Marine Starfire 1600 SC 2007 or the Starcraft Marine STX 186 Viper 2013?
The Starcraft Marine STX 186 Viper 2013 is the longer of the two at 18,5 feet overall. The Starcraft Marine Starfire 1600 SC 2007 comes in at 15,0 feet, making it roughly 3,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Starcraft Marine Starfire 1600 SC 2007 or the Starcraft Marine STX 186 Viper 2013?
For trailering, the Starcraft Marine Starfire 1600 SC 2007 has the edge at 805 lbs dry weight versus 1 763 lbs for the Starcraft Marine STX 186 Viper 2013. 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 STX 186 Viper 2013 is rated to a maximum of 175 hp, giving it the larger power ceiling. The Starcraft Marine Starfire 1600 SC 2007 tops out at 60 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 Starfire 1600 SC 2007 is Coast Guard rated for 6 passengers, while the Starcraft Marine STX 186 Viper 2013 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 STX 186 Viper 2013 measures 96" wide, compared to 85" for the Starcraft Marine Starfire 1600 SC 2007. 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 Starfire 1600 SC 2007 or the Starcraft Marine STX 186 Viper 2013?
The Starcraft Marine STX 186 Viper 2013 has the bigger tank at 43 gallons, versus 13 gallons on the Starcraft Marine Starfire 1600 SC 2007. That 30-gallon difference translates to roughly 90–150 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Starcraft Marine Starfire 1600 SC 2007 and Starcraft Marine STX 186 Viper 2013 from the same manufacturer?
Yes — both the Starcraft Marine Starfire 1600 SC 2007 and the Starcraft Marine STX 186 Viper 2013 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.
