Our Boat

Saint John

Mykonos Boat Rental Services | Sea Diamond – Mykonos Cruises

An authentic Mykonos experience could only be offered on an authentic Greek boat, like the ones that Greek sailors have been using for decades.

Saint John is a traditional motorboat built in Syros in 1997. The boat was completely refurbished in 2022 to ensure that it complies with the most rigorous safety standards. It has also been equipped with a variety of modern amenities and practical facilities so that it provides absolute comfort and luxury to every guest. And with a maximum capacity of nine people, you can rest assured that our spacious boat will comfortably accommodate your loved ones.

However, Saint John is not just a boat to transfer you from one place to another. It is a whole experience in itself. Its graceful bow features an inviting sunbed where you can enjoy a glass of Greek wine, while staring at the glistering waters and listening to the calming sound of the waves surrounding you. And when you feel like it, you can use the available snorkeling masks to explore the welcoming sea.
