Hi Rich.You may reconsider as back then as well as now, the captain made the crew repaint everything and bent on perfectly clean if not new sails to impress the owners upon their ship's condition thus promoting a future voyage.
Just a thought for your consideration of merchant vessels as well as naval. A good reading novel upon this is Dana's Two Years Before the Mast in the closing chapters. Rich (PT-2)
At the point of my proposed diorama of HMS Medea, she was returning to Britain from the Indies where she had been involved in four heavily contested battles with French ships and shore barrages. Based at Madras where there was only an exposed anchorage but no port, maintenance was difficult and materials scarce. Captain Gower WAS keen on painting and keeping everything shipshape but during wartime it was especially difficult. Following his journals indicates he suffered from lack of new stores and opportunity to obtain them.
But I take your point on board.
