Okay . . .

The question was what barges are tied up to the LST and the answer was barges do not tie up to the LST.

You're right, semantics are a matter of choice sometimes. The man who owns it calls it a "platform." And to me, calling it a barge is like calling an ant hill one of the Rocky Mountains, but who cares? It doesn't matter.

But it still did not tied up to the LST.
