This is my effort using the method described just to show you that the system works!
As a general rule, I work from top to bottom, keeping my paper in place with a piece of tape
along the top edge. I work with my supporting board flat or tilted forward only a little.
Leaving the sails areas untouched I wet the sky and a 'winsor blue' mix was added in small areas. I then added 'Cadmium red' sparingly to the mix and applied beneath some of the white areas to model clouds. You could use a wash of 'winsor blue' for a clear sky but remember that normally, and to add depth, a sky gets lighter as it approaches the horizon.
With the sky completely dry, (patience) each sail was filled with clean water and mixes of 'light red' and 'colbalt blue' applied sparingly as shadows to model the billow of the canvas.
The hull was then filled with a stiff mix of 'colbalt', 'burnt umber' and 'paynes gray'. When dry, the deck-cargo and masts etc. were filled with 'burnt sienna' and 'colbalt'.
Again, be sure that everything is dry before painting the sea. Sea area was wet (taking care not to leach water into the other painted areas). Leave a dry area for white foam aroung the hull, then fill the sea with a loose mix of 'winsor blue' and 'cadmium yellow'. Add wave form with slightly darker horizontal lines.
To further emphasise the shape of the sails the shadows cast by adjacent sails were added with 'light red' and 'colbalt' taking care to blend the edges to avoid sharp delineation.
To complete this module I have included a subject that is custom made for the system. The chair, which sits on the patio in my garden, is a complicated thing to draw. I photographed it and produced a print using my digital camera software. Using the method described above, I transferred the images, changing the composition slightly and produced a quick watercolor sketch. Why not try a few of your own.
