Step 1. Previously we do a sketch, strongly we do not remove the line. We draw the ship case.
Step 2. We draw masts.
Step 3. We draw sails.
Step 4. When the general plan is ready, now it is possible to detail a sailing vessel. Further everything is in details shown on pictures therefore I will not explain.
We draw the sky and a tea, the ship with sails at the sea is ready.
