A new use for a lobster trap
As the saying goes, when life gives you a lemon, make lemonade, so, when life gives you lobster traps, tie them up to the rudder of a ship so you cannot be followed while you make your way to escape with Captain Jack Sparrow. It is what Will Turner did in the first movie when he accidentally stepped into a lobster trap while he was getting away with Jack. Will turned his lemons into lemonade and used the trap he had comically stepped into as a way to make sure they couldn't be followed.
