how to find owners of superyachts looking for luxury yacht services crew?

Gday! My name is Antonique from Healing Arts International, I am thinking of travelling to Antibes from Sydney to offer my luxury yacht services in healing arts. like teaching holistic forms of stress management and relaxation,providing prof massagetherapy, wholefood as medicine, yoga.
I provide a sanctuary for owners and guests and crew where they can experience rejuvenating services in the healing arts and if there is a spa onboard a blissfull spa experience complemented with zen shiatsu treatments with diagnosis.
My question is How to find the owners seriously interested in a wellness therapist as well as a deckhand on board?

Any ideas?

Many good wishes
