The Pro-Line 26 Super Sport 2011 vs Pro-Line 31 Sport 2006 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 Pro-Line 31 Sport 2006 measures 32,0 feet overall (2006), giving it roughly 5,7 additional feet of deck space compared to the Pro-Line 26 Super Sport 2011 at 26,3 feet (2011). At 44 lbs and 7 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 600 hp, the Pro-Line 31 Sport 2006 has a 150-hp advantage over the Pro-Line 26 Super Sport 2011's 450-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Pro-Line 26 Super Sport 2011 carries 156 gallons versus 3 gallons in the Pro-Line 31 Sport 2006. 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 Pro-Line 31 Sport 2006 is rated for 9 passengers, while the Pro-Line 26 Super Sport 2011 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pro-Line 31 Sport 2006 could be the deciding factor.
Bottom line: Choose the Pro-Line 31 Sport 2006 if your priority is putting more people on the water — it handles 9 passengers and at 32,0 ft it has the deck room to back that rating up comfortably. The Pro-Line 26 Super Sport 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
