Tony,
You are "looking at" the possible installation of an elevated pad near a windy seafront, eh? But you're not looking to land on it yourself, eh? So...what, you're looking for reasons to stop it? What's your angle here?
Landing on an elevated deck near a seashore is no different than landing on an elevated deck anywhere else....except that there will probably always be some wind blowing. And that's a good thing.
