I've also seen a Westerly Warwick lifted with Barrels.
Sailors are resourceful, it's not rocket science.
Fred Drift alert!
Hundreds of years ago, as Amsterdam developed as a major trading port, and its depths reduced under various influences, they routinely used air-filled barrels (and also much more elaborate large purpose-made wooden caissons, called 'camels') that would be secured alongside a ship and then the water pumped out) to reduce the draft of commercial ships so they could get in and out of the shallow(ing) harbour.
I can't find the original article I read with a drawing or engraving of the barrels in use there, but the very interesting article about this (and other challenges and opportunities Amsterdam faced - the Zuider Zee & Nord-Hollandsch Kanaal etc.) linked following includes these images of a 1742 model of such a 'camel', and an old engraving of them in action.
