Does anyone have any experience with shipping yachts? I've seen ads
about very large cargo vessels that are used to transport small and
medium sized crafts from port to port.

I'm interested in moving a 45' catamaran from the Caribbean, up the west
coast, to the northwest (BC, Oregon or Washington) and would like to
review any possible options in this regard. I have seen an add in the
local sailing rag but am unaware of anyone having used this service.

Any pointers or info would be greatly appreciated.
