tambahan:
selamat berlayar semoga angin yang baik dan lautan yang tenang menyertaimu hingga selamat sampai di tempat tujuan

panjang yak

Jalesveva Jayamahe (Di laut kita jaya) is the motto of the Indonesian Navy. Not sure whether the men use this as a battlecry or A n equivalent of "fairwinds and following seas"
Marine Police use "Arnavat Darpa Mahe" (karena di laut kita bangga)

Sepengetahuan saya, tidak ada padanan langsung bahasa Indonesia untuk frasa seperti ini.

Memang, intinya frasa ini bermakna do'a keselamatan bagi mereka yang pergi berlayar.

'fair winds and following seas' adalah suatu kondisi lautan yang paling ideal dalam pelayaran.
fair winds = aning yang tenang
following seas = ombak dan arus laut yang bergerak dari arah buritan (bagian belakang) kapal. Dg kata lain, ombak dan arus yang searah dengan arah gerakan kapal.

Karena kalau diterjemahkan 'selamat berlayar' atau variasi lainnya seperti ini akan terdengar sangat umum dan tidak menggambarkan makna dan gaya bahasa asalnya, saya mengusulkan
fari winds and following seas = angin tenang dan ombak buritan

yah diindonesiakan sajah...

The phrase wishes the sailor(s) an ideal condition for sailing: favorable wind and waves, in other words, a smoothness in their trip.

If translated back, "semoga pelayaran Anda lancar" will be more or less "I wish your sailing is smooth and safe."

When you are looking for something poetic and rather literal, I suggest "semoga angin mendorongmu and samudera menyambutmu."

HTH.

Ref:
Are we puzzled about the origin or the meaning? I don't know when the phrase was first used, but it's a nautical benison. 'Fair wind' = 'may the wind fill your sails favourably for the duration of your voyage.'

'Following sea' refers to a sea swell that doesn't overtake the ship. It is very difficult to control any boat or ship when the swell overtakes it and shoves it forward, causing the boat to skew broadside-on to the wind and swell. Boats often capsize under such conditions.

Semacam Doa atau Yel-yel penyemangat

fair wind = favourable wind = tend to push
follow sea = go along (route or path)
