Proper drawings would be better but some of the better paper model publications have quite good info.
The M15 Class monitor along with a few destroyers would go well on the WWI Channel coast.
One of the succeeding class, M33, which is quite similar, is preserved in Portsmouth, England.
Here is another possibility, a German Torpedo Boat V-108, plans for a paper model available free from DigitalNavy.com
One of this class was still commissioned in the Polish Navy at the start of WWII
