The Pro-Line 29 Grand Sport 2009 vs Pro-Line 32 Express 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.
On paper these two are close siblings in the size department - Pro-Line 29 Grand Sport 2009 at 29,0 ft versus Pro-Line 32 Express 2006 at 32,0 ft. Weight tells a clearer story for trailering families: the Pro-Line 32 Express 2006 tips the scales at 9 500 lbs - 3 190 lbs less than the Pro-Line 29 Grand Sport 2009 at 6 310 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.
Both boats share a closely matched power ceiling - 600 hp for the Pro-Line 29 Grand Sport 2009 and 600 hp for the Pro-Line 32 Express 2006. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Pro-Line 32 Express 2006 carries 300 gallons versus 240 gallons in the Pro-Line 29 Grand Sport 2009. 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 32 Express 2006 is rated for 9 passengers, while the Pro-Line 29 Grand Sport 2009 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 32 Express 2006 could be the deciding factor.
Bottom line: Choose the Pro-Line 32 Express 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 29 Grand Sport 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
