Exploring the upper pool at Loch Tarbert
Here is a live recording made early in the morning on the 7 April at dawn.
The Kyle Rhea is a classic tidal gate with strong, fast-flowing tides that prevent vessels from sailing between mainland Scotland and the Isle of Skye.
Boats must use their yachting almanacs and tide tables to plan the best time for a successful transit.
The video is part of a sailing series film over three months of sailing along the West Coast of Scotland, in Normandy, the Channel Islands, the Solent, IOW, the South Coast of England and in Devon and Cornwall.
