As you can see here, I started first with a quick value thumbnail study to figure out where my darkest darks and lightest lights were going to go along with maybe one or two mid values. Next I painted in the light value of the boats wet-on-dry.
After painting a few dark values into the boats, I painted a light wet-on-wet wash for the water. After it dried, I painted in some darker values at the base of the fishing boats and added just enough wavelets to give the sea water a rippling effect.
Finally, I added the "jewelry" or final details to the fishing boats. I did not even come close to copying the myriad of details that I saw in my reference photo - just some simple shapes and values to give the impression of "boat stuff". Plan ahead with a value thumbnail study, figure out your painting progression, capture impressions, and don't flounder (pun intended) rendering fussy details.
