At very low tide it is possible to walk out to the remains of midget submarines which are the black objects on each side of the photo beside the waves with the anchor buoy in between and two people looking at the one on the left. There is more information of their interesting history and a close up of one of them taken on a previous visit here
The other photo shows a crude oil tanker anchored before going to Hound Point  and a huge jack up oil rig called the Rowan Gorilla V11. It has just travelled from Dundee and shortly will be going to New Zealand to work off shore.  Its legs are 185 m long and can drill up to over 10.6 km deep and the platform, which can be raised to the top, is capable of housing over 100 people.  I find it hard to imagine how it can travel half way around the world in rough weather and seas.
