Notice to Mariners

The following is a message that I recently sent to the FSC Cruising Section:

About three weeks ago Kim Klaka notified me of his success in his effort to have the DOT issue a Ntm regarding changing bathymetry of the Parmelia and Success banks during winter.

See notice 48 at http://161.152.28.103:10003/pls/lweb/notice_info?p_chart_id=WA%20001

Notice 48 is at the end of the above document, and states:
--------------------------------

48. Insert
Text CAUTION (See note 8) in positions
32° 04.28' S   115° 39.34' E
32° 07.71' S   115° 40.85' E
and text
8.  Parmelia and Success Banks are subject to seasonal shoaling, mariners are advised to navigate with caution. in position
31° 53.78' S   115° 46.60' E

-------------------------------

I hope that this notice will find its way to the next edition of the relevant DOT charts.

 The NtM appears vague because it is dealing with a vague problem.  However, to an experienced sailor in unfamiliar waters the phrase "seasonal shoaling" will jump out of the chart in large bold lettering.
