I greatly admire the marine paintings by Antoine Roux, father and son.  This watercolour of  a sloop taking in sail is based on one of their drawings, transposed from Marseilles to Plymouth Sound.  It is not completely unlikely, as ships were sometimes captured and changed sides during the Napoleonic wars.

This French barque, Idun, ran aground on the Suffolk coast  in January 1912.  I have tried to capture the watery sky that follows a stormy night.  The sail in the background might be the lifeboat, Alfred Corry.

Water in water colour this time.  This barge sailing down the Thames on a foggy evening made a simple and effective subject.
