I had a look this morning after reading your post. Around £80 and if it saves fuel and tolls then that is the solution.Been back in mine many a time. Newhaven Dieppe is a 4 hour crossing away from all the gimmgrunts and cuts a lot of kilometres off the trip and the traffiv jams around the tunnel/Dover. Last time I looked, off peak sailings one way could be had for £90 or less, tot up the fuel and tolls and for me it worked out cheaper. I like boats, I used to sail across the channel in my little boat, so four hours and a not too bad dinner en-route suited me.
Thanks again for your suggestion Keith.
