It's bad at sea, stormy — lots of info here (8)
I believe the answer is:
database
'lots of info here' is the definition.
'it's bad at sea' is the wordplay.
'it's bad' becomes 'base'.
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'sea' becomes 'data' (I can't justify this - if you can you should believe this answer much more).
'base' put after 'data' is 'DATABASE'.
'stormy' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
(Other definitions for database that I've seen before include "whole lot of information is needed" , "computer store" , "Lots of info" , "Computerised information" , "Computer's information store" .)
