In the past couple of months I have received a few separate inquiries about chasers in the post-war period, and whether there are any WWI-era hulls remaining.

While my focus is on the chasers during and shortly after the war, there are various sources of information about the later post-war service of the boats. The list of short accounts of French chasers (see the item on that, below) gives a thumbnail sketch of those 98 boats after the war; there was a multi-part article not long ago published in Warship International, and there are various accounts of specific boats here and there. 

Feel free to contact me with questions on individual chasers, with the disclaimer that the data I collect is mostly on the wartime period.

On the latter: I would be very surprised if there were any WWI-era chaser hulls still in service. That would be a spectacularly long life for a wood-hulled boat of this sort. The last traces I have found are from the 1970s. That being said, if anyone should hear of one, do let me know. Maybe there is an old hull in a barn somewhere.
