That's a pilot for you, Barrie! My take is that if a VLCC can transit the Channel then not much else should have a problem if adequately run. I had not thought of trying to berth her in Ramsgate. I don't think Grey funnel line has anything approaching that target aspect.
Might an unsatisfactory Brexit not alleviate that - If we assume larger vessels will have longer voyages and therefore longer delivery times these might be direct to large ports of entry where the customs formalities may be processed in a less frenetic fashion than ro-ro ports where the short sea traders are more likely to be and require matching clearance vehicle by vehicle.
