A gulf is a body of water partly surrounded by land and connected to an ocean or sea. This connection sometimes takes the form of a narrow passage called a strait. The nomenclature of water inlets can be inconsistent between sources. Sometimes, the terms
bay and sea are used interchangeably. For example, the Arabian Sea and Hudson Bay can both be classified as gulfs. However, in most cases a gulf is deeper and larger than a bay and is also more enclosed from the ocean or sea to which it is connected. Because gulfs are
partially surrounded by land, their waters are typically calmer than those of oceans. This makes them suitable for activities such as transportation, fishing and leisure.
