Thanks for your help Routier will look the RHA up for info and then investigate Ferry bookings and whether you have to provisionally book in advance or can you leave it to a day or 2 before.I guess if we book direct will have to set up an account first but will look at agencies as well . Being as the delivery point is 60miles from Calais will look to go out in the morning and return pm.
I used to use these for shipping, you can pay per trip over the phone
The discounts with the ferry companies are hard to get , depneds on your volume etc
