Частая ошибка:
Learners sometimes confuse "reef" with "wreath" (a ring of flowers). A reef is connected with the sea and is usually long and narrow, not ring-shaped. Another mistake is using "reef" for any underwater mountain; a reef is specifically close to the surface and can be a danger to boats.

reef the mainsail
|reef the sails
|reef down

Синонимы
