According to the regulations of the Cabinet of Ministers, winter navigation in all Latvian ports begins on December 15 and ends on April 15. Winter navigation means that the shipowners are obliged to prepare their ships for safe navigation in negative air temperatures during such a period of time. Equipment for de-icing the ship's hull must be provided on board.

The decision on starting ice navigation in the Port of Liepāja, as well as on the necessity of using icebreakers, is taken by the Liepaja Harbor Master, based on the operational situation in the waters of the port. The icebreaker service in the Port of Liepaja is provided by a commercial company, whereas the Harbor Master is responsible for the operational management of the icebreakers.

In order to organize safe navigation, it is recommended that small ships equipped with VHF radio station constantly provide radio communications on VHF channel 11.

It should be noted that any vessel traffic participant who can safely navigate outside the main shipping lanes must not obstruct the movement of vessels along them. Movement of yachts and small vessels in the harbor must be done by not disturbing the vessels sailing along the fairway. When sailing in the waters of the Port of Liepaja, one must abide by the “Regulations for the Traffic of Vessels in Internal Waters” and the “Regulations of the Port of Liepaja”.

Yacht, cutters or leisure boats are considered a small vessel if unless their length does not exceeds 24 meters.

Navigation for yachts and leisure boats is permitted in the City Canal.

The speed limit for small vessels in the City Canal is 5 knots (9 km/h). In the rest of the harbor area, there is no speed limit, under the condition, that the speed shall not not endanger other traffic participants, people, moored vessels and other floating or stationary structures, especially considering the influence of the waves created by the particular vessel.
