I've spent very little time next to oceans, but quite a lot of time near
the northern Great Lakes where, despite the lack of salt, one sees the
same sort of "flagging" in conifers along the shorelines.  Winds off the
lakes can be strong and cold in the winter and they probably kill exposed
buds on the windward side more frequently than on the protected side,
hence most lateral growth is away from the lake and wind.  The problem
would be more severe the taller the tree... I wouldn't be surprised if
salty wind has other effects - anyone know? 

Brings back fond memories...
