Best Customer Loss: Well, if England as a market takes a massive "huff", that may well be a concern, but I'm guessing that cross-border trade between England and Scotland will still be a better bet, and less expensive than cross-channel. We'll see.

Proximity, like inertia, makes a big difference. Huge amounts of trade between the US, Canada, and Mexico just because we're all here side by side. Habit and proximity are natural forces probably nearly as strong as gravity. Don't underestimate them.

The UK will not, nor ever has had ships built for the Royal Navy outwith the UK. Orders for the Type 26 number 18 or 20 in addition to those for the Indian Navy will be built under licence in India.

Sounds like a crap shoot here.
