In theory, for an ideal design, there would be no vibration. In practice, there are limits to where you can stick the prop and some boats are known to have a problem like that. You'd have to find other Dufour owners to ask about that. If you can't confirm/refute that, then as others have said you have to check the shaft, bearing, prop, to see if everything else is OK.
Sometimes it is as simple as someone putting on too big a prop--because they wanted more power under sail. And you might want to keep it, or change it out. No way to tell what prop is down there without getting eyes on it.
Also consider that if you don't want to pay for a haul (or diver) before the sale, you can ask for an escrow provision in the contract, where a certain number of dollars are put aside in an escrow account against the possibility of certain specific repairs, i.e. seller to pay up to $1000 for drivetrain repairs if worn or damaged prop, prop shaft, strut, or cutless bearing is found by a professional within 30 days after the sale. That gives you the chance to haul the boat for inspection and repaint after you own it, and if the seller is SURE there's no problem...neither of you is at risk.
