The earliest sailboats that we know of existed around 5,000 years ago in ancient Egypt.

Since even most modern sailboats primarily use wind for propulsion, they are very eco-friendly compared to their counterparts, especially those that use fossil fuels.

Most sailboats have a keel on the bottom of the vessel, which is crucial for stability and for countering the force of the wind. Without it, the boat is much more likely to capsize.

Sailboats can actually sail faster than the wind under the right angle and conditions—a phenomenon known as apparent wind.

People who sail boats against the wind use a technique called tacking.

Competitive sailboat racing began in the Netherlands in the 17th century.

A type of sailboat known as clipper ships could actually outrun steam-powered ships during long-range trips in the 19th century.

The fastest known sailboat can travel at speeds of around 75 mph.

Wing sails are a modern addition to sailboat design, inspired by airplane wings, which increase the boat’s efficiency.
