Levels relevant to this sailing

Departing Sunday 11 October 2026.

This page does not say whether your cruise will run. It shows what the rivers on your route are reading now, how far that sits from the water a ship of this size needs, which of your days are level-sensitive at all, and where to read the authority's and the operator's own pages.

Your itinerary, by kind of water

  1. Day 1 Amsterdam In port
  2. Day 2 Zons; Cologne Free-flowing Dutch & Belgian waterways · Lower Rhine
  3. Day 3 Koblenz; Boppard Free-flowing Lower Rhine · Middle Rhine gorge
  4. Day 4 Boppard; Rüdesheim Free-flowing Middle Rhine gorge
  5. Day 5 Germersheim Free-flowing Middle Rhine gorge · Upper Rhine
  6. Day 6 Strasbourg Held by locks Upper Rhine
  7. Day 7 Breisach Held by locks Upper Rhine
  8. Day 8 Basel Held by locks Upper Rhine

4 of 8 days on this itinerary sit on free-flowing water, where the level is the constraint. 3 are held by locks, and 1 is alongside.

These chips describe the kind of water each day sits on — geography, not a forecast and not a judgment about your sailing. A day held by locks does not care about a drought upstream; a free-flowing day is where the level is the constraint.

The corridors this itinerary crosses

Waterlogged clear-line, using an assumed 1.60 m draught. A Waterlogged clear-line is our own arithmetic: the gauge reading at which the published reference depth, minus the ship's draught and a fixed safety allowance, still leaves a comfortable margin. It is not an operator's decision rule and no cruise line uses it.

What Uniworld publishes

Waterlogged does not interpret your contract and does not calculate what you may be owed. These are the operator's own pages and the dated facts we could establish about them.

  • Named disruption programme found: not found in the documents read
  • Terms differ by booking market: yes, on the evidence read
  • Confidence in that finding: confirmed
  • Last checked: 2026-08-01

What we could not establish:

  • Which 2026 regional terms and legal seller are incorporated into the passenger's booking
  • Whether the operator applies the booking-contract or vessel-carriage deadline to the specific complaint
  • Whether mandatory law creates a cash-refund election despite a regional contract's stated default

Operator policies change without notice and differ by booking market and contract version. Waterlogged does not calculate your refund, credit, hotel entitlement or insurance payout, and does not determine cancellation rights or legal remedies. Read the operator's own documents and the terms attached to your booking, and do not cancel pre-emptively on the strength of river data alone.

Four questions worth asking your operator or agent:

  1. Which dated regional contract and disruption-program version applies to my booking?
  2. What does that document say for this specific itinerary change, and who decides whether it applies?
  3. What are the consequences if I cancel or reject a proposed change before the operator acts?
  4. What notice, evidence and deadline does the current document require, and where must it be sent?

An alert here is a measured centimetre crossing on a named gauge — never a score, a probability or a changed opinion.

Request the Daily River Log Watch for this sailing. We keep the address only for that request: no marketing and no sale of the address. The morning email for a served sailing is sent each day until the morning after it ends; a sailing we do not serve sends nothing until we serve it. See Privacy for retention and deletion.
