I'm with you Capt Fathom.....
Luckily the water appears to be about 1/3 of a fathom....but what is the tide doing??
I reckon I would have closed the door too!!
Might as well try to minimise the damage.....not really 'waterproof' doors I know, but......'minimum' damage is good ......
Otherwise, ALL out OK - so, Excellent result in the circumstances.
Cheers.
