I'm pretty sure that this is an urban (or maritime!) myth.
As far as I understand things it also makes no difference whether or not you broadcast a Mayday message. If someone does claim salvage it doesn't mean that they then "own your boat" as the salvage claim in all but the most extreme cases will be assessed as a proportion of the boat's value.
In most cases any claim for salvage will be dealt with by your insurance company.
It would be good to get a definitive answer from someone with a legal background. Maybe one of the insurance companies would know, as they have a definite interest in this sort of thing!
