Other mast will go to the back of the boat, next to captain's cabin. This one serves as an antenna. The antenna head is made from jeep parts and a mesh from an electric shaver. The wiring is made from a metallic guitar string. The thicker tubes are ballpoint pen bodies. Besides the mast, you can see the the tires in the photo prepared as side bumpers. Additionally, some small fins are shaped into sharper corners from plane tail-wing parts.
For easy attachment, I glued a sound jack on the bottom of the antenna mast (not shown in the picture), it now plugs in and out easily. Here is the this week's final shot with the parts attached on the ship:
