The word(s) "sea" appears 85 time(s) in 79 verse(s) in Quran in Muhammad Pickthal translation.

(21) The road (of blame) is only against those who ask for leave of thee (to stay at home) when they are rich. They are content to be with the useless. Allah hath sealed their hearts so that they know not.

(22) But as for those in whose hearts is disease, it only addeth wickedness to their wickedness, and they die while they are disbelievers.

(23) He it is Who maketh you to go on the land and the sea till, when ye are in the ships and they sail with them with a fair breeze and they are glad therein, a storm-wind reacheth them and the wave cometh unto them from every side and they deem that they are overwhelmed therein; (then) they cry unto Allah, making their faith pure for Him only: If Thou deliver us from this, we truly will be of the thankful.

(24) And We brought the Children of Israel across the sea, and Pharaoh with his hosts pursued them in rebellion and transgression, till, when the (fate of) drowning overtook him, he exclaimed: I believe that there is no Allah save Him in Whom the Children of Israel believe, and I am of those who surrender (unto Him).

(25) Then he (Joseph) began the search with their bags before his brother's bag, then he produced it from his brother's bag. Thus did We contrive for Joseph. He could not have taken his brother according to the king's law unless Allah willed. We raise by grades (of mercy) whom We will, and over every lord of knowledge there is one more knowing.

(26) Giving its fruit at every season by permission of its Lord? Allah coineth the similitudes for mankind in order that they may reflect.

(27) Allah is He Who created the heavens and the earth, and causeth water to descend from the sky, thereby producing fruits as food for you, and maketh the ships to be of service unto you, that they may run upon the sea at His command, and hath made of service unto you the rivers;

(28) And He it is Who hath constrained the sea to be of service that ye eat fresh meat from thence, and bring forth from thence ornaments which ye wear. And thou seest the ships ploughing it that ye (mankind) may seek of His bounty and that haply ye may give thanks.

(29) Such are they whose hearts and ears and eyes Allah hath sealed. And such are the heedless.

(30) (O mankind), your Lord is He Who driveth for you the ship upon the sea that ye may seek of His bounty. Lo! He was ever Merciful toward you.
