Is a channel a narrow strait?

Yes, a channel can be considered a narrow strait, as it typically refers to a body of water that connects two larger bodies of water and is often narrower than the surrounding areas. However, the term "channel" is broader and can also refer to any navigable waterway, including rivers or artificial passages. In contrast, a strait specifically denotes a naturally occurring narrow passage between two landmasses. Thus, while all straits can be seen as channels, not all channels are straits.
