Not sure how to put this!
(With GPS), Mrs A and I went to Newtown today. Pub: The New Inn - excellent pheasant (I had the last one, so no good for anyone tomorrow!). Got back safely and no sign of the harbourmaster
You went (despite GPS!) to NEWPORT not NEWTOWN (although the tides for both are important!).
I went to Newport two weeks ago - The Bargemans Rest: http://rib.net/forum/showthread.php?t=27119
We also heard the shout today for Grey White (heard "Dry White" although at my age .....)
but didn't hear the conclusion....
Hope all was well but agree with you that tasking the Swanage lifeboat for their location seemed a little strange.
