Is the Strait of Belle Isle rough? What to expect on the crossing
It can be, but the crossing is short. Labrador Marine's St. Barbe to Blanc-Sablon ferry takes 1 hour 45 minutes. The operator says southwest winds bring bigger seas than northeasterly winds, because the route is open to the Gulf, and that the sea state can stop a crossing even after the wind drops.

Key facts
- The Strait of Belle Isle is a strait, and passenger reports place it in the high roughness band.
- The mechanism behind that reputation: Southwest Gulf swell, tidal current and ice.
- It is also known as Détroit de Belle Isle.
Why is the Strait of Belle Isle so rough?
The strait is about 125 km long and between 15 and 60 km wide. Wikipedia describes navigation as extremely hazardous, with strong tidal currents interacting with the Labrador Current, sea ice for 8 to 10 months of the year, and gales and fog. Labrador Marine says southwest winds bring bigger seas than northeasterly winds, because the route is open to the Gulf. The swell from a northeasterly wind generally subsides faster.
When is the Strait of Belle Isle roughest?
Wikipedia says the strait has sea ice for 8 to 10 months of the year. Labrador Marine says its winter schedule often brings delays due to ice conditions, and that difficult ice may increase the crossing time. It ties bigger seas to southwest winds rather than to a season.

What helps on this crossing
- Check the wind direction as well as the speed. Southwest winds bring bigger seas here, and a northeasterly swell subsides faster.
- Look at the horizon during the 1 hour 45 minute crossing, not at a screen.
- Check Labrador Marine's travel advisories and the 511 line before you drive to the terminal. During delays the Qajaq W runs on a load and go basis, with very little notice.
- Dizzout, a drug-free sound therapy app for passengers: it works with any headphones once nausea starts, with relief in about 90 seconds.
For the full toolkit see the seasickness guide, or what to do once it has already started. For what the trials actually say about the oldest trick on that list, see the verdict on looking at the horizon. If the rocking follows you ashore afterwards, that is land sickness, which is normal, and it passes.
