The picture is from the annual Helsinki season end regatta Tervasaaren Tynnyri (Tar Island Barrel) for traditional sailing vessels (Oct 10th 2020). The race had 17 vessels participating, both local and some long distance visitors, with the furthest coming from Iceland. The vessel in the picture is (three mast topsail schooner) Svanhild is cruising at 9 knots with the crew hiking on the rail.
The majority of the participating vessels base their livelyhood on charter trips, which due to Covid have been scarce, so it was a pleasure to see so many out sailing that day. Photo thanks to Ville Vappula.
