Sunday evening.

After a bit off woodwork I've made a start on the shipboard derricks. These are just a 6mm main mast, with 4mm booms pinned to the mast with short bits of bras rod.

Its looking a bit more boaty.
Now to answer the question in the last posts comments.
I'm not planning to have is visible from the backside as I have a plan to put the point throws in the guts of the ship and run the wire through to under the wharf.

Now, if I could just find a local supplier of 3-4 bags of Pecos track pins (they are useful for so many more things than pinning track).
