The Velocity 322 2010 vs Velocity 390 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 Velocity 390 2007 measures 39,0 feet overall (2007), giving it roughly 7,1 additional feet of deck space compared to the Velocity 322 2010 at 31,9 feet (2010). Weight tells a clearer story for trailering families: the Velocity 390 2007 tips the scales at 8 000 lbs - 1 050 lbs less than the Velocity 322 2010 at 6 950 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 - 525 hp for the Velocity 322 2010 and 525 hp for the Velocity 390 2007. 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 Velocity 390 2007 carries 200 gallons versus 125 gallons in the Velocity 322 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Bottom line: The Velocity 390 2007 at 39,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Velocity 322 2010 at 31,9 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
