An alternative to a normal wreck dive on the Thesis is a drift dive onto the wreck itself. By choosing the right state of the tides divers can drop in at the Chimney.
Visibility is usually good.
Descending to the seabed at 14 metres the tide will carry you towards the wreck and deeper water. By maintaining a depth of between 22 and 24 metres the centre of the wreck will be reached. Depths above or below this will take divers around, missing the wreck. Approaching the wreck the water tends to slacken and a dark shadow looms ahead. At this point the wreck is directly in front.
