Default "sawdusting" wooden hulls

Anyone out there familiar with the process of "sawdusting" a wooden hull? I was reading an old article by Bud Daily where he mentions that they had to sawdust the leaking hull of the gasboat EDNA.

My first thought was that you somehow get sawdust in the water around the hull where it would be sucked into the cracks that are leaking, or apply it by hand directly to the cracks by diving. I know that when we get lots of fine debris in the water, the small leaks in my old steel deck barge stop leaking.

Not sure if it would work from the inside of the hull, but my other guess was that they forced saw dust into the cracks where the old oakum caulking is (fon the inside of the hull), and the sawdust gets wet and expands and slows the leaks(?)

This seems like a topic that I haven't seen on the board... Just curious!
