The Pro-Line 26 Super Sport 2013 vs Pro-Line 29 Grand Sport 2007 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 - Pro-Line 26 Super Sport 2013 at 26,3 ft versus Pro-Line 29 Grand Sport 2007 at 29,0 ft. Weight tells a clearer story for trailering families: the Pro-Line 29 Grand Sport 2007 tips the scales at 6 310 lbs - 1 910 lbs less than the Pro-Line 26 Super Sport 2013 at 4 400 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 500 hp, the Pro-Line 29 Grand Sport 2007 has a 50-hp advantage over the Pro-Line 26 Super Sport 2013'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 29 Grand Sport 2007 carries 240 gallons versus 156 gallons in the Pro-Line 26 Super Sport 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 Pro-Line 29 Grand Sport 2007 at 29,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Pro-Line 26 Super Sport 2013 at 26,3 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.
