“Imagine a bubble,” says Sara, our yoga teacher, her voice soft, her accent French. “A champagne bubble, if you prefer, in the colours of your favourite sunset. Inhale, and as you exhale, imagine that bubble dancing over the ocean, into the sky, taking away your cares.”

It’s not much of an ask. If I raise my head from my mat and gaze along Le Ponant’s top deck, past the barely fluttering tricolour flag and the outdoor bar with its cocktail shaker and chilling bottles of Veuve Clicquot, inspiration is there on the horizon.
