Critical tidal warning — many anchorages dry completely at LW

Many anchorages in Groningen and the Ems estuary dry completely at low water (LW). Plan ALL arrivals for HW -2 hours or better. Ems estuary shipping (Papenburg shipyard cruise ship transits) can close the entire river for 24–48hrs — check Wasser- und Schifffahrtsamt Ems (wsv.de) before approach. Eelgrass anchoring fines apply in UNESCO Wadden areas. Daylight-only navigation mandatory throughout.

Set Your Anchor Alarm Before You Sleep

In the Groningen Wadden and Ems estuary, many anchorages dry at low water. A dragging anchor can strand you on a tidal flat. Safety Anchor Alarm monitors your GPS position continuously.
