First to cross the Panama Canal
What boat was the first to cross the Panama Canal?
The first boat to cross the Panama Canal once it was opened was the S.S. Ancon, carrying a cargo of cement on August 15, 1914.
If we're counting test runs and boats that went through the canal while working on it before the official opening, then the Alexandre La Valley gets that honor, having made the trip on January 7, 1914.
