A very small bay or a minor inlet of water.
From 'bay' with the diminutive suffix '-let,' which comes from Old French '-elet.' This suffix was borrowed into English to create smaller versions of things, similar to how 'booklet' or 'droplet' work.
English's system of diminutive suffixes like '-let' and '-ling' reveals how the language economically creates new words—rather than inventing entirely new terms, we just append suffixes to existing words, which is why a baylet is instantly understood even if rarely used.
