The pumps on the Sultana are quite beautiful, particularly in the long curve of the handles.
I started work on the binnacle by creating a 3D design with the lid on.
The Sultana has four hatches. Two are small: one is located aft of the windlass and the other is forward of the binnacle. A long, medium sized hatch is on the quarter deck, and will be open to expose the ladder on my model, as it is on other Sultana models. Finally, there is a large hatch on the main deck. Most models depict the main hatch covered with boards, but on the Sultana replica, the large hatch has grating and a ladder down.
The picture below is of the medium hatch, with the grating in place to cover the ladder. Note the white cover. All of the hatches on the Sultana have these covers, which keep out water. However, I think I will omit the white covers.
This details building the ladder. First, one side of the ladder is created. The fillet feature allows the ladder to be rounded off at the top.
Let’s build the windlass, starting with the ratchet gear. After studying a number of pictures of the Sultana’s windlass, I determined that the ratchet gear has 12 teeth. I created a 12 sided polygon and added one tooth.
