Namely a German U-boat (submarine), a Tug boat and many little worker boats ferrying precious resources to the mother hive.
Here are some close-up pics of a German WWII movie taking place in Cape Town. I am not sure of the details (we only had to carry the all important German Press) but it allowed us to get pretty close to the dangerous submarine, although only a replica I believe.
Also included in this post is the get-away boat! Enjoy.
