When two boats share the same hull type — in this case both the Velocity 290 SC 2009 and the Velocity 390 2009 are modified vee designs with composite 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 Velocity 390 2009 measures 39,0 feet overall (2009), giving it roughly 11,0 additional feet of deck space compared to the Velocity 290 SC 2009 at 28,0 feet (2009). Weight tells a clearer story for trailering families: the Velocity 290 SC 2009 tips the scales at 465 lbs — 457 lbs more than the Velocity 390 2009 at 8 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 700 hp, the Velocity 390 2009 has a 100-hp advantage over the Velocity 290 SC 2009's 600-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 290 SC 2009 carries 8 gallons versus 2 gallons in the Velocity 390 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Bottom line: The Velocity 390 2009 at 39,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Velocity 290 SC 2009 at 28,0 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.
