@Moon_Raker

A moonraker was Quote “a foolish person,whom upon seeing the reflection of the moon in the water,believed it to be cheese”. Unquote…west country English folklore…In the mid 18th century,contraband (port,rum)was smuggled by ship into the estuaries of the rivers and sunk…Later to be retrieved by the moonrakers when the “coast was clear”…One was caught and the judge laughed at his explaination about the moons reflection and didn’t hang him…That I can assure you,is the true legend of a Moonraker and why i have the name

That makes the most sense of anything in this thread, but have you any links we can follow to further research it?
