Boat transport Med-Baltic

I'm considering moving a boat from the French Riviera to the Baltic. Is Dover the first reasonable place for filling up diesel? What do I have to pay for diesel earlier on my trip? Thanks in advance for your advice. Also interested ín offer from merited transfer skipper for the Riviera-Br. channel leg.

Dover:- red diesel is allegedly nearly 40p a litre in Dover. and a similar price in Ramsgate as well I understand. try and wait until you get to the east coast before you re-fill Peggy
