Hello Mark,
I'm not sure if your requirement is still open, but in the event that it is I may be able to assist. I am an experienced offshore racing skipper and have my own blue water cat as well (currently in the Philippines, but due to make its way home starting in March or so next year). In the meantime I am looking for a ride back to NZ for Christmas. I am a New Zealander, fully jabbed (Moderna), have an ESTA and able to travel at short notice.
Cheers
Pete
