A person who speaks in a posh tone of voice, is usually wealthy but does not necessarily sail atall, yet still hangs around yacht clubs to fit in. They usually wear expensive yachty clothes.
She is such a yachty.

Refers to one usually but not limited to a male. Someone who dresses to look as if they would be in a Yacht Club. Usually ironic because of their lack of wealth, and quite possibly pretty broke. They look expensive. They might look like they're wearing Lacoste or Izod.
Look at that cute yachty over there, with his argyle sweater vest and button down.
