The Pro-Line 29 Super Sport 2006 vs Pro-Line 31 Express 2005 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.

Both boats share a closely matched power ceiling — 600 hp for the Pro-Line 29 Super Sport 2006 and 600 hp for the Pro-Line 31 Express 2005. 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 31 Express 2005 carries 312 gallons versus 192 gallons in the Pro-Line 29 Super Sport 2006. 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 31 Express 2005 is rated for 9 passengers, while the Pro-Line 29 Super Sport 2006 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 31 Express 2005 could be the deciding factor.
