Many of the WWI-era subchasers saw varied and exciting post-war service: chasers were used as training vessels, fishing boats, merchant boats, rum-runners … all kinds of things.
An interesting example is submarine chaser SC 196. During the war this chaser served in the Fifth Naval District. SC 196 was sold to Joseph A. Hitner -- who purchased quite a few decommissioned chasers -- and it was converted for use as a fishing vessel. It was later known as the Mary A. Edwards, and then Talisman.
See the photo set submitted by Howard Anderson (details below) for photos of the chaser as the Mary A. Edwards. Information and photos/video of the wreck are posted on the North Atlantic Dive Expeditions website.
