The Sea Fox 216 2006 vs Sea Fox 240 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 Sea Fox 240 Viper 2013 measures 24,3 feet overall (2013), giving it roughly 3,3 additional feet of deck space compared to the Sea Fox 216 2006 at 21,0 feet (2006). At 22 lbs and 33 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 300 hp, the Sea Fox 240 Viper 2013 has a 100-hp advantage over the Sea Fox 216 2006's 200-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Fox 216 2006 carries 101 gallons versus 9 gallons in the Sea Fox 240 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 8 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 Sea Fox 240 Viper 2013 at 24,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Fox 216 2006 at 21,0 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.
