Seagoing Ship

liner, ship

Mnemonic

A boat painted brilliant white from bow to stern is no humble river vessel — it's a Seagoing Ship, an enormous craft built for crossing oceans. Picture that dazzling white hull slicing through deep blue waves, hauling foreign treasures from distant ports back home.
Additional thoughts
Large ships were traditionally painted white to be visible on the open ocean. White + boat = upgrade from small craft to grand ocean vessel. Think of a gleaming white cruise liner or cargo ship.
Quick recall
A white boat massive enough to cross oceans is a Seagoing Ship.
