ehm, I think the ISAF report is comparing oranges with oranges as all quotes are given when picking the boat up at door of the factory ex taxes or delivery and all agents assemble the boat locally.

Other then that, it is all a zero sum game. If nacra extrude theirs masts in NED then that will mean additional shipping costs to non-european customers as indeed will be the case the other way around.

Mind you the Superwing used by AHPC is fabricated in California USA and is shipped directly to the local agents and not via AUs.
