They talked about TOR which they haven't won yet!The present rules do prevent any sailors from moving, unless they have a passport for the new teams country.
Brought in immediately after the previous event, ostensibly to take the event back to its roots. The reality being it was to stop any Kiwi sailor being able to work for a foreign syndicate in a sailing position. It did not cover designers, which would have been more like the original events, as Kiwi relies on foreigners to perform this function.
So B & T are not able to move to a different team. What they could do is decide they have had enough and have no wish to be part of a team that abandons NZ and go for some other sailing achievements. For some time they have been mentioning other paths they could be interested in.
