A yacht, strictly speaking, is any boat that is used for pleasure.
True, the word yacht has connotations of luxury and grandeur.
But, it's the pure element of pleasure that makes a boat into a yacht.
I do understand that some of the newer features that some sailors nowadays think are "necessary" have been added to boats so as to improve safety or help make up for a lack of hard-to-get crew.
But what happens when boats become so complicated and on-board systems so fragile as to remove the pleasure from boating? Is it no longer yachting if boat ownership turns into indentured servitude?
What happens when boat owners become so psychologically addicted to various systems that even minor breakdowns keep boats in port? Can people learn to differentiate between systems needed for functioning and safety versus fluff?
Do Laser sailors (that is, the ones who enjoy being inverted into frigid water until their teeth chatter and lips turn blue) therefore enjoy more "yachting" than owners of large, elaborately cruising boats with delicate or poorly planned and installed systems?
