Do yacht stabilizers work at anchor, and will they prevent seasickness?
Some systems are designed to reduce roll both underway and at anchor; the exact installation matters. Quantum’s technical material distinguishes underway and zero-speed operation and describes stabilization as roll reduction—not elimination of every motion or a promise against seasickness.

Ask for:
- Manufacturer and installed system.
- Confirmation of at-anchor capability.
- Current operating condition and any known limitations.
- Whether the system will normally be used overnight.
- The captain’s advice on anchorages and passage planning for motion-sensitive guests.
Keep two questions separate: “Is the equipment fitted?” and “Will the operating plan make practical use of it?”
For the shortlist, specify at-anchor stabilization as a requirement if it matters to your group. For the itinerary, request shorter passages and alternatives to exposed overnight locations where practical.
For individual prevention or medication advice, consult a clinician rather than relying on equipment claims or charter marketing.
