Larry - we couldn't find any rates, in containers or on a barge, cheaper than $5,000+-. It might be possible to load two 22-foot C-Dorys into a container and split the cost - but it would be mighty tight and perhaps not a good idea if there were rough seas. We thought it would be great to ship over, spend two or three summers cruising the waterways of Europe, and perhaps then sell over there to avoid the costs of return shipping. But, it finally dawned on us that maybe it would be much less costly to buy a used boat over there, use it two or three summers, and re-sell it.
Anyway, when we hit on the idea of doing a 'commercial' trip on the rivers, and maybe charter canal boats for more cruising, that seemed the best way. So we chartered in England and now are on a commercial boat for this trip.
