I believe that this part of the approach to Castries Harbour St Lucia is used for the berthing of the Island's Coastguard vessels. I draw this conclusion because the largest cutter in this image is the Alphonse Reynolds P-01 that previously saw service with the US Coastguard. The image was captured during a Tropical storm in November 2010. I have posted a much larger image of the Alphonse Reynolds in the Customs and Coastguard Sub Gallery of this Web Site along with some details of her history.
