When my 24 Pantera went to England, it went on a Ro-Ro (roll-on, roll-off) on it's trailer. Seems like it was still pretty pricey and this was back in 2005.

For those who may be on this same quest. I found this site.

How accurate it is I dont know. But for $4k seems a bit less than I had expected. This was for a 26f Deep v to italy from florida. With insurance and all the fees included.
