Wooden Boat

The following is the drawing of wooden boats in Anggrem Harbor of Manokwari city. The boats play an important role in sea transportation connecting the coastal villages along the Cendrawasih (Geelvink bay) with the capital of West Papua province.  The average lengths of the boats are 20 to 30 meters with diesel engine as the main propelling power.
Drawing wooden boats manually as part of ship design job was an exhaustive task for me as a student of naval architecture. Now it is not difficult anymore due to the availability of cad drawing software for ship and boat design such as Delfship, Maxsurf, Rhino, Foran and etc. The time needed for manually drawing lines plan of a small boat was around three days to one week. With the help of Delfship or Maxsurf, we can design the lines plan within hours including watertight sub-division, resistance and propulsion calculation and hydrostatic assessment. Delftship can also be used to design the general arrangement of the boat. The design of linesplan and general arrangement, including the interior of the boat can be done simultaneously in Delfship, a robust cad drawing solution for naval architecture. Well, that's my opinion about drawing a boat from the engineering perspective.
Now I still draw boats manually not for ship design purposes but for artistic expression. Art drawing and cad drawing are different in process and purpose. In art drawing, an artist create beautiful drawing as final product. He or she begins sketching the boat hull, superstructure and the sea as her surrounding environment using pencil and then color it with colored pencil, watercolour or oil paints.
For naval architects, the drawing of lines plan, general arrangement and construction details are seen as tools to communicate design ideas to workers in workshops for later use in ship or boat building process. So, the drawings created by naval architects are not seen as final products but as tools to communicate ideas to those working in shipyard for the construction of the boat or ship.
If you see the above picture, you can easily say that it is an art drawing. Yes, there are boats in it but they are only artworks. The drawing cannot be used for construction. The drawing is a piece of artwork. To make the drawing, I had to visit the port of Anggrem in the Dorey bay of Manokwari city, the capital of West Papua province of the Republic of Indonesia. There, I took some photographs of the boats and used them later for writing articles in this blog and as reference for my drawing hobby. Because I studied naval architecture, I know the working principles of boats and ships but I do not want to discuss them here since the topics of boat design are very complicated. I present the above boat drawing in this post to you only to attract your attention to this wonderful watercraft or marine vehicle. I hope you can enjoy it. I will try to upload more drawings in my later posts. Thank you. by Charles Roring.
