Text: Until recently, there was little for ordinary mortals who lacked a yacht, but now there are sailing fleets waiting to be hired either bare (for qualified sailors) or with a crew to do the work for you.
Entailment: Nowadays it's possible to experience sailing even if you don't have experience or the money to buy a yacht, because there are plenty of places to hire a yacht, or a yacht with a crew.
Contradiction: If you don't have a yacht, it will be impossible to get to experience sailing one.
