port side

I'm a little stuck... Click here to teach me more about this clue!

'left at sea' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'moving spider to' is the wordplay.
'moving' is an anagram indicator.
'spider'+'to'='spiderto'
'spiderto' is an anagram of 'PORT SIDE'.

'be' is the link.
