I tried dealing with the shipping company Joe has mentioned, "Get Routed".
The organizers of the Australian Vincent Rally in 07 put this company forward as the shipper to use for international attendees. We found them impossible to deal with. His requirements for us were for something like a minimum of ten machines from each port. We had seven at our port, so he would not ship us. In additon, his price was very high at around $3,000 return for ocean shipping, as I recall. I knew this was high as I had just ocean shipped a single bike from Australia to Vancouver for $320 one way, handling the details myself.
In any case we could not meet his minimum shipment number in most ports, so he would not ship our bikes.
In Vincent circles the company became known as "Get Stuffed"
Those that did ship from my area Air shipped one or two bikes per shipment for approximately the same cost as Get Stuffed wanted for the mass ocean shipment.
The Vincent Rally in OZ did not get the good attendance that a V. Rally a few years ago in NZ did, and I think a good deal of this was due to the difficulties and costs involved in shipping. The NZ bunch had all of the shipping details worked out at a reasonable cost. One member had an empty warehouse that was used to store the Ocean shipping crates during the Rally. With the OZ Vincent Rally, no one stepped forward to do this and storage became a problem. Many people who had planned on attending just threw up their hands when they realized the difficulties ahead and saw that there would be no offer of help at the other end.
Joe, if you can make it easier in any way for people to get their bikes to and from OZ, it will increase attendance greatly. "Get Routed" did not work out for us.
