The document analyzes shipping in the Central Baltic region, including Estonia, Latvia, and Sweden. It finds that shipping is most intensive in Swedish waters passing Gotland and heading to the Gulf of Finland, and around the port of Riga. In Estonia, the ports of Pärnu and Saaremaa Harbour are highlighted as important for regional and international connections. Requirements for shipping include space for lanes and routes of various vessel types and sizes. Future developments may include changes to vessel sizes and routes. Transboundary alignment of shipping routes is recommended.
