Insurance for driving in Georgia?

Hi all. Next month my car, ocean rowing boat and I will be making a trip through Europe (I will row the Black Sea while friends continue the drive). I know I have to buy car insurance at the border for Turkey, but does anyone know about Georgia?! Are there UK companies that cover for driving in Georgia? Its not part of the EU but is a European country so hoped that there may be some that do cover there (as the RAC breakdown covers Georgia!)

Thanks all!
