Your concept is 100% right.
The only thing wrong was the terminology.
To cross the T, means to present YOUR (emphasis) broadside to your opponents bow.
The old sailing ships carried their guns along both sides, with very little, or more likely, no cannons in the bow.
Wikipedia article:

It actualy goes back further than wikipedia states, with it's origins in The Royal Navy. but the examples they show will suffice.
(And again, your tactic for attack is perfect.)
