Looking for a boat to join around the Fiji islands

We are Romane and Fanny, 2 friends from France, respectively 28 and 31 years old. We have been travelling together for a bit more than 5 months around asia and Oceania, and spent 4 of them living in a van (so we are very used to tiny spaces and keeping it tidy !).
We just arrived arrive in Nadi, Fiji. Since the beginning of our trip we have been thinking of sailing in the islands to live a different adventure, travel differently (with low carbon emission), meet people and stay away from the big touristic resorts as we are always trying to avoid crowded places. Now this idea has grown in our minds. We would love to spend part or all of our last month of travel (end of May to end of June) on a boat for a sailing adventure.
Experience in sailing: we are no sailors but fit, fast learners, hard workers, and we can do many things. Romane used to sail with her grandfather when she was younger and know the basis of sailing, and Fanny grew up on the French Riviera, sailing Hobie Catamaran during summers and her parents had a boat rental company so she’s been around boats and at sea a lot. We are very enthousiats about a sailing adventure and we are sure we can be useful, helpful and of good company.
We are very easy going, respectful, enthousiasts and open minded. We love to meet new people, we have a big sense of humour (hopefully this opinion is shared by others), we are tidy and we don’t smoke. We absolutely love nature and animals and are always ready for an adventure. We are also always kean on helping and sharing.
We are also big sea lovers and divers.
