Sea-going is a term used to describe something that is designed or suitable for travel or operations on the sea. However, there are many synonyms that can be used in place of sea-going, such as seaworthy, nautical, marine, ocean-going, sailing, maritime, shipboard, seafaring, flotational, and aquatic. These terms are often used in marine and nautical contexts to describe ships, boats, equipment, products and services. While some of these terms, like ocean-going or marine, tend to be used in more professional or technical contexts, others like seafaring and sailing are more commonly used in a broader sense to refer to activities and culture around the sea.
