Captain Jon Spiller

I am wanting to know the whereabouts of my friend and colleague Jon Spiller. We used to be regular correspondents, but I have not heard fom him for nearly a year. E-mails to his address on board Lady Christina do not receive a response, either from him or whoever reads the e-mails.
He was supposed to enter and sail his yacht in last year's ARC, but a check on the entrants revealed that he did not compete.
I have tried many avenues to contact him and hope that this forum might generate some response.
Please help.
