I agree with all of Steve's comments but would add the following after UNCLOS in the second definition of Continental Shelf: "Article 76"
For definition 7, I surmise that TSMAD's line of thinking would be that a Restricted Area is such whether or not it is shown on a chart. However, in the context of the Hydrographic Dictionary I think it is best to retain "and shown on charts".
Definition 9 - Sea-plane landing area - I agree this is common sense, no need to include this term
I am happy with the proposals made by Jerry. I have prepared a new document incorporating Jerry's views and presenting the definitions as amendments to the existing S-32 definition where it exists. Red italic = new text and strikethrough = deleted text. I suggest that we use this document as thye basis for any further discussion.
