I recently came across an interesting article about a WWI chaser wreck, SC 241 - The Mysterious Wreck in the Hanover Flats, by Ray Freeden of Marshfield, Massachusetts. It's a good example of a post-war use of a chaser: at one time possibly a rum-runner, later as a private boat and finally as a makeshift home.

I added a couple of notes on the stats -- but the story is entertaining and worth reading, and gives a good sense of what happened to these boats after the war.
