Before starting any Superstructure work I thought it might be a good idea to fit the Propellor Shafts, Screws and Rudder, as these would have been more difficult later in the build when there would have been the risk of damaging something above deck.
The central Cones on the screws were a bit tricky to make (check out the printed piece for one of them below), but I'm more than happy with the results
.
