nautinada
Nautinada is a term sometimes used colloquially to refer to a large gathering or event involving boats, particularly in a celebratory or recreational context. It is not a formally recognized term in naval or maritime terminology but rather an informal descriptor that has emerged in certain communities. The word itself appears to be a portmanteau, combining "nautical" or "nautilus" (relating to ships or sailing) with a suffix suggesting a gathering or celebration, similar to how "fiesta" or "parade" might be used.
These events can range in scale from informal flotillas of personal watercraft to more organized regattas
