The Pro-Line 29 Grand Sport 2011 vs Pro-Line 35 Express 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.
Size is the most obvious dividing line here. The Pro-Line 35 Express 2007 measures 35,0 feet overall (2007), giving it roughly 5,7 additional feet of deck space compared to the Pro-Line 29 Grand Sport 2011 at 29,3 feet (2011). Weight tells a clearer story for trailering families: the Pro-Line 29 Grand Sport 2011 tips the scales at 631 lbs — 519 lbs more than the Pro-Line 35 Express 2007 at 112 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 900 hp, the Pro-Line 35 Express 2007 has a 300-hp advantage over the Pro-Line 29 Grand Sport 2011's 600-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 35 Express 2007 carries 32 gallons versus 24 gallons in the Pro-Line 29 Grand Sport 2011. 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 35 Express 2007 is rated for 10 passengers, while the Pro-Line 29 Grand 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 35 Express 2007 could be the deciding factor.
Bottom line: Choose the Pro-Line 35 Express 2007 if your priority is putting more people on the water — it handles 10 passengers and at 35,0 ft it has the deck room to back that rating up comfortably. The Pro-Line 29 Grand 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.
