It is your Lord who drives the ship for you through the sea that you may seek of His bounty. Indeed, He is ever, to you, Merciful.
Al-Mukhtasar fi Tafsir
Your Lord - O people - is the one who makes the ships sail for you in the sea, hoping to seek your sustenance through the profits from trade and the like. He is Merciful to you as He facilitated these means for you.
Tafsir Ibn Kathir (abridged)
Your Lord is He Who drives the ship for you through the sea, in order that you may seek of His bounty. Truly, He is ever Most Merciful towards you (66)
Ships are a Sign of the Mercy of Allah
Allah tells us of His kindness towards His servants by subjugating for them ships on the sea. He makes it easy for them to use ships to serve their interests, seeking His bounty through trade between one region and another. He says:
إِنَّهُ كَانَ بِكُمْ رَحِيمًا
(Truly, He is ever Most Merciful towards you.) meaning, He does this for you out of His grace and mercy towards you.
