Here’s a shot on the Sultana looking forward. The rails at the bow are somewhat complicated. The knightheads stand proud on either side of the bowsprit. Working along the rail, there are three cleats, then the rail is broken by the cathead. After the cathead, there are seven timberheads, which are wider at the top.
This picture shows my final design for the forward rails. There were several iterations to get things where I was satisfied.
This picture shows how the timberheads were angled to match the slope of the bulwarks.
And this is the design of the cathead.
All the pieces were 3D printed. Here are the pieces for the starboard side. All pieces were gently sanded and painted matte black prior to gluing.
Two shots of the pieces after being glued.
