I'd say it is.

Note the algorithm i sketched in its simple form would seriously 
underestimate the bay size due to the peninsula in the middle - same 
problem as small islands in the bay which i already mentioned.  It is 
fairly easy though to detect and fix this (by making use of the fact 
that a bay is 'mostly surrounded by land').

On a general note the established tagging conventions are of course not 
well suited for tropical coastal landforms dominated by mangrove.  
Technically you might also consider the inner bay a lagoon rather than 
a bay.
