Renowned sailing journalist Matt Sheahan runs the Youtube channel PlanetSail, covering racing to cruising, boat reviews to new kit, analysis, commentary and news in the sailing world.

In this episode, Matt interviews offshore sailor Sam Davies, who explains the leap in performance with the new generation foils. Davies and her co-skipper Paul Meilhat were the first to fit the new blades last season and had thousands of miles under their belts as they started this year's Transat Jacques Vabre. They are also well ahead of the curve when it comes to understanding how to work with intelligent autopilots. Sam's fascinating explanation of how it all works is matched by some mesmerising images of the boat at full chat along with what life's like on board.
