In general, Lithuanian waters are very shallow. At most places it is wise to sail in the marked fairways. Sometimes you have to sail 5-6 NM from the nearest land. The shallow waters makes harbours rare. But there are small and charming fishing harbours! Some of them have excellent service for yachtsmen. Here you can often find a sauna, electricity and a bar. The ports are often manned both day and night.To sail in Lithuanian waters, you need good charts! Russian ones are of highest quality. Newly corrected Russian charts are sold in many countries.
Buoys and beacons show up as expected. Leading lines are often hard to see, but with the help of buoys and harbour plans, you can managed anyhow. But beware of the lights! The lights are often out of order. Do not rely on the lighthouses either. Don't navigate in darkness! You can navigate without problem at daytime. In darkness - that's totally another story. Plan your visit to June and July, when the days are long!
