Around high water at Hansweert, the W side of the channel turns to ebb while the E side keeps flooding. For up to an hour the currents oppose each other across the fairway and an eddy forms off Walsoorden. HF radar, 30 Sep 2026.

1/25 The night of 9 October 1799, a British frigate ran onto a sandbank off the Dutch islands of Vlieland and Terschelling. Some 240 people were aboard; one survived. She carried gold and silver worth around a million pounds. Most of it is still down there. #maritimehistory #otd

Painting of a three-masted warship heeling hard in a storm, sails torn and a British ensign flying, waves breaking over her stern, which carries the name La Lutine.

The whole Westerschelde, from the border with Belgium (right) to the Dutch/Belgian coast on the left. It shows why a pilot sometimes prefers (or avoids) taking a secondary fairway because the current might change sooner than in the main fairway (draught permitting)

1/x Two of the best-known coats on any high street began as working kit for sailors on cold decks. Both carry names from my little corner of the North Sea: Duffel, a small town near Antwerp, and the Dutch word "pij". The story of the duffel coat and the peacoat. #maritimehistory

You've probably seen those train maps. I thought I would try the same with ships. My first experiment. Ship traffic in the Southern North Sea from 05:30 UTC to 14:15 UTC (my capture was interrupted, but fixed now, so the next map will be 24hr period)

Belgian Navy Frigate Leopold I is not deploying for the ASPIDES maritime security mission. The ship has a defect and cannot be repaired in time.... *shrugs*... of course not... even now, some politicians don't realise the urgency. The fact that Be Air Force delivers the CHoD doesn't help either.

1/x Have you ever heard of a ship that raced another ship with her crew and passengers in a drunken stupor, hit a rock, and caused almost two decades of civil war? One man survived. “No ship that ever sailed brought England such disaster”. This is the story of the White Ship. #maritimehistory
