What on earth is this referring to ?
Traditionally all vessels enter a dock, especially a dry or floating dock sharp end first.
The shapes of many are designed for this method of entry.
So, why would a ship enter either dock types blunt end first, unless she be so seriously damaged as the option to go stern in first is essential.
I have come across this once only in the huge No 2 dry dock Rosyth.
There must be numerous other instances.
Come on you lot. Answers here please or send me a postcard with such illustrated. Second class will be sufficient.
