The line there has always been battered by the sea ever since it was built by Brunel no matter what you do you will never stop it.
I myself have been through there many times with sea coming over and believe me it isnt a very nice experience, they do have single line working over the up line when it gets really bad.
As for going inland there has been talk about it many times, there is an old line from Heathfield Newton Abbot to City Basin Exeter closed in 1968 link below
