Somewhere I also remember reading that the Irish Sea is much deeper
than the English Channel, which makes tunnelling more difficult than
the tunnel length would suggest, but I haven't been able to verify
that
From a wander around GOOGLE I find......
The Irish Sea is a semi enclosed shelf sea bordered by the island of
Ireland, Scotland England and Wales. The depth in the western Irish
Sea is characterised by a channel of greater than 80m depth that runs
from St. George's Channel in the south to a maximum depth of 275m in
the North Channel.
also...
The English Channel has a maximum depth of 100 m at the western mouth
(5deg W) shallowing to 40 m in the central Dover Strait
Which does confirm your memory.
Does depth make a difference? It won't be cut and cover!
