Sailboats like the America's Cup hydrofoils, iceboats, and the iceboat on wheels land yacht, can all go faster than the prevailing wind by using the sail as a wing. Wind blowing around the the sail produces lift just like an airplane wing, but because the sail sticks straight up, the 'lift' generated pulls the boat forward.
They can only make these high speeds when sailing into a quartering wind.
None of the above can sail faster than the wind going directly downwind.
