No, those wanting to travel to international events will always have to bite the bullet with respect to costs. If you're relying on shipping firms, be it trucking companies, air freight, or even shipboard containers, you are at the mercy of their timetables, security requirements and rates. I found it interesting in trying to become vetted as a non-terrorist to enable me to ship my boat even within the US (I trucked Try-Foil to Portland and back for the Gorge worlds.) Overseas airfreight was even more problematic in 2008. I could not ship my boat to England without going through the Newport Hood sailloft, a connection I got through George Peet.
On a related note, I notice from Alan's recent post that the Belmont PRO is Peter Moor. I wonder if it's the same Peter Moor that participated in the '76 Ware River Worlds. That Peter Moor was the reigning Australian Champion at the time and finished 2nd in the '76 worlds in a borrowed skiff (he did use his own rig.) Why didn't he bring his scow (which also can't fit into a current hull travel box)? No doubtedly because of travel costs.
Peter Moor sailing at Ware River in 1976 in a skiff (I think it was a Poacher or a Stockholm Sprite) that he borowed from Ted Causey, the eventual winner. Note Moor even bolted a tube extension onto the box wings to make the beam the full 7'4".
