That the wind has bellied the sails and starting to propel the vessel.
ALMOST as fast as the wind!
By auxiliary engine
Water like the sea or lakes, but the sails sail on the wind and air. Hope this is the answer you were looking for!
Wind energy is used to sail boats, and turn wind mills to make flour.
Wind. You can also attach a machine that spins in the wind, generating electrical power.

Wind power propels sail boats, and powers wind turbines. It is not as widely used as coal, natural gas or oil.
To sail against the wind, a boat has to 'tack'. This means that instead of sailing straight into the wind (which would get you nowhere) you sail in a zig-zag in the direction you intend to go. On each tack, the wind is on a different side of the sail.
Wind motion is the type of energy used by kites and sailboats.
Assuming both boats are under sail, and both boats have adequate visibility, the position of the wind will determine which is the stand-on vessel and which is the give-way vessel. If each vessel has the wind on a different side, the one with the wind on the port side keeps clear. if both have the wind on the same side, the vessel nearest to the direction of the wind keeps clear.
They don't 'sail'. They might move due to some other force acting on them however. This could include currents, tides etc.
Sailboats are designed to utilize wind power for navigation, allowing them to sail across bodies of water. They typically feature sails that catch the wind, enabling them to move forward. In contrast, motorboats rely on engines for propulsion and do not sail. Therefore, among various types of boats, sailboats are the ones that can sail.
