Passage · SIG260930

Amsterdam → Basel

Nine reach tanks (min / current / projected), then a Kaub-style official + WSV series for Basel, Maxau, Mannheim, Mainz, Kaub, Koblenz, Köln, Duisburg and Emmerich, then the Getaway ports by embark date. Tanks show water over the sill, not raw pegel cm. Ports stay red / yellow / green from min sailable, today, WSV at that noon when it exists, and usable draft after 30 cm UKC. Kaub is the gate. WSV hourly outlook is about four days; 1–6 week chips are BfG weekly means at Maxau, Kaub, Cologne and Duisburg. Later Getaway calls without a matching week are colored from today.

Nine reaches · min, current, projected

Height is water over the controlling sill, not the pegel number. Kaub 28 cm on the gauge is about 1.4 m of water. Min to sail a Longship is ~1.6 m (≈ 48 cm at Kaub).

Dashed green on a tank is the GlW fairway. Red tick is ~1.6 m — passing impossible for a Longship. Tap a reach for its series and the threshold brief. Today / 2 days / 4 days use WSV hourly WV (Kaub, Koblenz, Köln, Duisburg, Emmerich). 1–6 weeks use BfG weekly means (ensemble median) at Maxau, Kaub, Cologne and Duisburg — twice-weekly, not a daily pegel. Basel, Mannheim, Mainz, Koblenz and Emmerich have no official week outlook.

The Rhine at each controlling pegel

Basel, Maxau, Mannheim, Mainz, Kaub, Koblenz, Köln, Duisburg and Emmerich — each with its own official series. Blue is PEGELONLINE. Dashed is the WSV 4-day outlook where that station publishes WV (Kaub, Koblenz, Köln, Duisburg, Emmerich). These are gauge centimetres, not true depth in the cut. Every Rhine pegel on the corridor is stored on each Refresh; the nine below also keep a 31-day backfill.

Current sailings

Sections of the Danube, Elbe and Rhine Rivers have experienced abnormally low water levels this summer. As a result, select Viking river itineraries may be modified. While recent rainfall has provided some improvement, precipitation has been sporadic and conditions remain dynamic. Water levels remain below normal in certain sections of the rivers, and some itinerary adjustments may still be necessary. Viking's nautical and operational teams are closely monitoring conditions and working to minimize any impact to guests' travel experiences. Viking Customer Relations is proactively notifying guests and their Travel Advisors prior to departure if the guests’ itinerary may be affected.

VIKING · CURRENT SAILINGS · LIVEDanube, Elbe & Rhine — 9 SEP 2026

Checked 14 Sept CT from vikingrivercruises.com/my-trip/current-sailings. Sections of the Danube, Elbe and Rhine Rivers have experienced abnormally low water levels this summer. As a result, select Viking river itineraries may be modified. While recent rainfall has provided some improvement, precipitation has been sporadic and conditions remain dynamic. Water levels remain below normal in certain sections of the rivers, and some itinerary adjustments may still be necessary. Viking's nautical and operational teams are closely monitoring conditions and working to minimize any impact to guests' travel experiences. Viking Customer Relations is proactively notifying guests and their Travel Advisors prior to departure if the guests’ itinerary may be affected. Viking is uniquely positioned to manage water-level situations such as these. We have decades of experience navigating Europe's rivers, the largest river fleet in the industry, which we own and operate, and mor Treat as active until a new dated notice prints or Kaub recovers through GlW and holds. 60% FCC remains the published concession — rejected on this desk.

AIS LIVE · 8 SEPT–14 SEPT0 full Amsterdam ↔ Basel Longship transits

Live AIS 10 Longships. 0 in the Kaub cut. 0 full AMS↔Basel. Kaub 28 cm vs GlW 77 cm binds every hull. Positions from Open Waters / AISHub, Swiss-flag (269) hulls named VIKING * in the Rhine–Benelux box. Each live pull writes a sample so hull tracks accumulate. A complete AMS↔Basel AIS transit would be an escalate. AIS jitter and a one-cycle dark hull are not.

LINE POSTURE60% FCC is the published concession

Through Q3 Viking has been keeping the product running (swap, coach, hotel nights) and issuing future-cruise vouchers in the 60% band rather than unwinding the fare. Rejected on this desk. A 60% voucher plus a bus/hotel substitute is not a Rhine Getaway.

THIS RESERVATIONNo named guest CR letter as of 14 Sept

As of today’s pull, no named letter is on file in this desk. Another ship’s 60% letter is not yours. Do not reopen the agent on a fleet-wide rumor. Hold until a letter or named swap prints on this reservation, or until Kaub actually recovers and holds.

USABLE DRAFT · LIVE111 cm after UKC · Longship 1.5–1.8 m

Fairway at GlW is 190 cm. Kaub 49 cm below GlW → ~141 cm in the cut. 30 cm UKC → 111 cm usable. Conflict remains −40 to −70 cm depending on hull. Lightening a Longship does not make a 1.8 m ship into a 1.1 m ship.

08 · Escalate rules

Tight trigger only
  1. Named CR letter or named sister-ship swap print on this reservation — not another hull’s 60% note.
  2. A published cancel of this sailing, in writing, to the named guests.
  3. Gauge step-change only — Kaub recovery through GlW (~77 cm) and holding, or a further collapse that changes the operational story. Drift around 25–35 cm is not a new fact. Live Kaub is 28 cm.

Do not reopen the agent on rumor, AIS jitter, or another ship’s 60% letter. Hold the two-outcome ask.
