Transitioning from the tideless, calm waters of the Baltic Sea to the roaring currents of the North Sea and the English Channel was one of the biggest leaps we’ve ever made in sailing. As we exited the Kiel Canal and pointed our bow down toward the North Sea and English Channel, neither of us had ever sailed in tidal waters before. Sailing our Bavaria 37 with our dachshund Nora onboard was an incredible journey, but experiencing tidal currents firsthand was a whole new masterclass in seamanship.
If you are planning to take your boat out of the Baltic and head west, here are 5 lessons, tidal strategies, and practical tips we learned along the way.
1. Tides: A True Love-Hate Relationship
Tidal currents quickly became a classic love-hate relationship for us. When the current is pushing behind you, it’s absolute magic - you get a fantastic boost of extra speed over ground that makes you feel like you're flying.
On the flip side, it can be deeply frustrating. There is nothing quite like holding a steady 5 knots through the water, only to look at your GPS and realize the current is so strong against you that you're actually moving backwards over ground! Planning your passages around the tidal stream (with the tide vs. against the tide) is everything on this coastline.
2. Mind the Harbour Depths & Lock Gates
In tideless Baltic waters, a depth reading stays constant all day long. In the English Channel, tidal ranges can easily exceed 6 to 11 meters! In Lezardtriux, France we experienced an 11 meter difference between high and low tide.
Always pay attention to whether a harbor offers floating pontoons or fixed quay walls, and keep an eye out for harbor sills (seuil). Many harbors along the French and UK coasts feature sill gates that only open a few hours around high water. Arrive at the wrong time, and you’ll find yourself waiting outside in open water or anchor-bound until the water rises again.
Also, keep in mind that tidal harbors can mean climbing long steel ladders or negotiating steep ramps at low tide when taking your dog ashore for walk
3. Current vs. Wind: The Wave Factor
One of the biggest surprises for us and many other Baltic sailors is how fast sea conditions change when the wind blows against the current (wind-over-tide). Even a modest 15-knot breeze can create steep, square, and uncomfortable waves if the tide is running hard in the opposite direction.
Our humble tip: Always check the tidal stream direction before setting off. Waiting just two hours for the tide to turn in your direction can turn a brutal chop into a smooth, fast ride.
4. Cruising with a Dog: Border Control & Realities
Cruising with a pet requires some extra preparation, but it doesn't have to be nerve-wracking.
Make sure you have all the necessary paperwork, EU Pet Passport, microchips, and rabies vaccinations completely up to date before setting off. However, don't stress too much when border officials approach! When the French customs boarded us and we nervously asked if they wanted to inspect Nora’s passport, they literally just laughed at us. It turned out to be completely relaxed, but having the documents properly in order gives you great peace of mind.
5. Staging Strategy & Harbor Arrival Times
Popular landfall harbors along the North Sea and English Channel fill up very quickly during the cruising season. Boats arriving just an hour after high water often find visitor pontoons completely packed, forcing them to push through night shifts to find the next available shelter. Having a clear idea of harbor options and layout beforehand makes your route planning significantly smoother.
Plan Your Route with Our Cruising Guide
Sailing from the Baltic out into tidal waters is a big milestone, but having a clear overview of the harbors along the route makes planning much easier.

Very good information. I would never climb up such a tall steel ladder against the sheet piling – I’d rather have waited six hours.
