@VesselFinder @ArctiaLtd In other news, the Swedish #icebreaker Ale is repositioned from Lake Vänern to Holmsund. Oh, and #icebreaking assistance has again been suspended to four northernmost Finnish ports in the Bothnian Bay due to adverse ice conditions — likely heavy compression within the ice pack.

@VesselFinder Last in — first out: the Finnish #icebreaker Sisu, which was deployed to the Gulf of Finland in the beginning of February, has concluded its #icebreaking season and has returned to @ArctiaLtd's icebreaker base in Helsinki as the season's first homebound icebreaker.

I guess it's time to start the customary Baltic Sea winter navigation thread for the 2025–2026 season. I will be tracking #icebreaker movements and other interesting events. Latest Finnish ice reports and ice charts can be found at @meteorologit: en.ilmatieteenlaitos.fi/ice-conditions

Chinese shipbuilder Guangzhou Shipyard International has filed a patent application for what seems to be some kind of rudder headbox (CN121608852 A). Nothing new under the ice. Similar construction can already be found in e.g. RRS Sir David Attenborough and RSV Nuyina.

Our field team has just returned from the sunny Bothnian Bay where we are carrying out fortnightly ice channel measurements on the Kemi-Tornio fairway. This work is part of the SNAIL (Study on NAvigation in Ice channeL) project funded by the Winter Navigation Research Board.
