Sailing route: from Mariehamn to Tallinn

Route Mariehamn–Pirita (158.3 NM, ~31.7 hours) begins in the Åland archipelago, departing Mariehamn (60.0981N, 19.9247E). The initial sector is dense with skerries and shallow patches—maintain vigilant watch and precise navigation, especially near 60.0848N, 19.9269E. Depths can vary rapidly; unlit rocks and isolated shoals are frequent hazards. Use updated charts and radar in poor visibility.

After clearing Åland, you enter the open northern Baltic Sea. Here, prevailing winds are southwesterly to westerly (summer averages 10–18 knots), often producing moderate seas. Monitor forecasts for rapid weather changes. Traffic density increases near main shipping lanes, especially approaching the Gulf of Finland. Cross the Helsinki–Tallinn route with caution; large ferries and commercial vessels maintain high speed and limited maneuverability.

Approaching Pirita (Tallinn), traffic intensifies, and fishing gear may be present. The final approach (59.4713N, 24.8157E onwards) is well-marked but busy—watch for local traffic and observe all traffic separation schemes. Maintain continuous AIS and VHF watch throughout the passage.
