To sail in Latvia, you need good charts! Russian ones are of highest quality. Newly corrected Russian charts are sold in many countries.
In general, Latvian 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 yachts. Here you can often find a sauna,
electricity and a bar. The ports are often manned both day and
night.
The typical navigational situation is that you approach a port
holding well out from the shore. You find the buoy (a
safe water mark) marking the beginning of the fairway to the
port. From that position, you only have to follow the buoyage
towards the port. In the chart you find the course leading in.
Coming closer, and with a little luck, you can also find the
beacons marking the leading line.
Buoys and beacons show up as expected. Leading lines were 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!
