The Pro-Line 29 Super Sport 2010 is a deep-V design and the Pro-Line 32 Express 2009 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Pro-Line 32 Express 2009 measures 32,0 feet overall (2009), giving it roughly 3,4 additional feet of deck space compared to the Pro-Line 29 Super Sport 2010 at 28,6 feet (2010). Weight tells a clearer story for trailering families: the Pro-Line 32 Express 2009 tips the scales at 9 500 lbs - 4 200 lbs less than the Pro-Line 29 Super Sport 2010 at 5 300 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 Super Sport 2010 and 600 hp for the Pro-Line 32 Express 2009. 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 2009 carries 300 gallons versus 192 gallons in the Pro-Line 29 Super Sport 2010. 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 2009 is rated for 9 passengers, while the Pro-Line 29 Super Sport 2010 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 2009 could be the deciding factor.
Bottom line: Choose the Pro-Line 32 Express 2009 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 Super Sport 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
