Matching a modified vee Starcraft Marine 1600 DC 2010 against a deep vee Starcraft Marine STX 206 Viper 2013 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.
Size is the most obvious dividing line here. The Starcraft Marine STX 206 Viper 2013 measures 20,5 feet overall (2013), giving it roughly 4,6 additional feet of deck space compared to the Starcraft Marine 1600 DC 2010 at 15,9 feet (2010). Weight tells a clearer story for trailering families: the Starcraft Marine 1600 DC 2010 tips the scales at 855 lbs — 831 lbs more than the Starcraft Marine STX 206 Viper 2013 at 24 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 300 hp, the Starcraft Marine STX 206 Viper 2013 has a 240-hp advantage over the Starcraft Marine 1600 DC 2010'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 1600 DC 2010 carries 13 gallons versus 5 gallons in the Starcraft Marine STX 206 Viper 2013. 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 206 Viper 2013 at 20,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Starcraft Marine 1600 DC 2010 at 15,9 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.
