The Velocity 360 2007 vs Velocity 400 Xover 2009 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 - Velocity 360 2007 at 36,0 ft versus Velocity 400 Xover 2009 at 39,0 ft. Weight tells a clearer story for trailering families: the Velocity 360 2007 tips the scales at 7 500 lbs - 500 lbs more than the Velocity 400 Xover 2009 at 7 000 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.
The power gap is worth calling out. Rated to 600 hp, the Velocity 360 2007 has a 300-hp advantage over the Velocity 400 Xover 2009's 300-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Velocity 400 Xover 2009 carries 400 gallons versus 200 gallons in the Velocity 360 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Bottom line: The Velocity 400 Xover 2009 at 39,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Velocity 360 2007 at 36,0 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.
