When two boats share the same hull type — in this case both the Pro-Line 29 Grand Sport 2008 and the Pro-Line 32 Express 2010 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Pro-Line 32 Express 2010 measures 32,3 feet overall (2010), giving it roughly 3,3 additional feet of deck space compared to the Pro-Line 29 Grand Sport 2008 at 29,0 feet (2008). Weight tells a clearer story for trailering families: the Pro-Line 29 Grand Sport 2008 tips the scales at 631 lbs — 536 lbs more than the Pro-Line 32 Express 2010 at 95 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 2008 and 600 hp for the Pro-Line 32 Express 2010. 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 29 Grand Sport 2008 carries 24 gallons versus 3 gallons in the Pro-Line 32 Express 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 2010 is rated for 9 passengers, while the Pro-Line 29 Grand Sport 2008 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 2010 could be the deciding factor.
