The catamaran slips away from the marina and the island’s white cliffs grow taller, sharper, as the Aegean pulls at the hull. On a semi-private sail limited to 12–18 guests, the crew trims the sails and the caldera unrolls: pumice-streaked Red Beach, the chalky White Beach, and the low, smoking rim of the volcano itself. The sea dares you to dive in; the crew hands you a mask and the engines drop to a hush.
