Storm warnings before a charter trip: decide safely instead of risking it

Quick answer

A storm warning shortly before or during a trip is no reason for risky decisions. Weather services, warning levels, and coordination with the charter base help with the assessment. Trip cancellation and curtailment insurance can apply if the trip is cancelled or cut short as a result.

Strong winds and storm warnings are part of sailing – what matters is handling them correctly. This article shows how to interpret warning levels and which cover helps in a real emergency.

Reading warning levels correctly

National weather services usually classify warnings into several levels, from strong breeze to hurricane force. For trip planning, storm warnings from wind force 8 and severe weather warnings involving thunderstorms or heavy rain are especially relevant.

Reliable sources for the weather forecast

  • National weather services for the relevant sailing area
  • Marine-specific forecasts and sea area forecasts
  • Warnings issued by the charter base on site
  • VHF channel 16 for current safety announcements

When cancelling the trip makes sense

When a storm is forecast, thunderstorm fronts with strong gusts are expected, or visibility is limited, safety should clearly come before the schedule. Staying in harbour or taking a shortened route is almost always the better choice than a risky departure.

Never ignore an issued storm warning because of a tight schedule – in doubt, the safety of crew and yacht decides, not the return flight.

Which insurance applies in a real emergency

A storm warning alone doesn’t automatically mean that a travel insurance policy will cover the costs. What matters is always which events are actually insured under the specific policy.

If an insured extreme weather or natural event occurs during a trip that has already started, and the trip therefore cannot be continued or completed as planned, curtailment insurance may apply. Depending on the policy, this can cover things like additional return travel costs or unused travel services.

If a booked trip cannot start at all because of bad weather or a storm warning, this does not automatically mean cover applies under trip cancellation insurance. It’s worth taking a close look at the specific policy conditions here.

Damage to the yacht itself generally falls under hull insurance. For a charter yacht, the agreed excess and possible deposit insurance can also be relevant for the charterer.
