It almost looks like it’s moving under its own steam, but in reality this is of course the very strong tidal current in the Sound of Islay racing past the Black Rocks buoy. Seen from the Islay ferry on a crossing to Port Askaig.
A view from the Islay ferry on a beautiful April afternoon: In the foreground the low hills of Kintyre, behind it the hills of the Isle of Arran (who gave its name to one of the Islay ferries).
The MV Eilean Dhiura crossing from Islay to Jura on a very clear April afternoon in 2015. In the middle distance the small lighthouse at Carragh an t-Sruith on Jura. Behind it the north of Colonsay and in the far distance the Isle of Mull with Ben More (the only island Munro outside of the Isle of Skye).
