We’re in the middle of the North Sea and it’s a breezy and bright afternoon.
On the port side we spot an area of sea, perhaps 3 metres radius, that seems to be boiling.
We chased to the back of the ship and I snapped these with my iPhone.
You don’t see that every day!
UPDATE: Another picture of the ‘boiling sea’ where we first spotted the Twister.

It’s big news to us because we never see twisters in Ireland (or they are very seldom).
