About Calyia
Our Story
Giannis Diamantidis, Founder & CEO of Calyia Yachting, is a super yacht captain with more than 20 years of experience. His connection with the sea began at the age of six, growing into a lifelong passion that eventually led him to captain super yachts and create Calyia.
Calyia is a boutique yacht charter company based in Greece, designed to share the beauty of the country’s stunning waters with travelers from around the world. The project was meticulously crafted over the course of five years before it ever set sail. During this time, the vision was refined, the sailing experience perfected, and the foundation built for a truly personalized journey at sea. Today, Calyia offers unforgettable sailing adventures, each one carefully curated to meet the unique desires of every client.
