Symbolic of the empowering of the Holy Spirit or prophecy, 2 Peter 1:21
(Captain; Manager; Ship) In a dream, the sails of a ship represent its captain, or they could represent a good manager, or they could mean gaining power.
If one sees sails being raised to honor him in a dream, it means that he will attain power, leadership, honor and exaltation.
If a ruler or a general of an army sees such a dream, it means that he will remain strong and secured from enemy attacks.

1- Sails suggest the idea of making use of available power. Often the type of sail will be relevant. Old-fashioned sails would suggest out-of-date methods, whereas racing sails might suggest the use of modern technology.
The colour of the sails may also be important (see Colour).
2- Because a boat or ship is usually thought of as feminine, the sails in dreams can represent pregnancy and fertility. By association, they can also signify how a woman will use her intellect.
3- Sails represent the Spirit as in a force that moves us.
