The port of Faro in Algarve is situated behind the low islands, or rather 
salt marshes which form Cape St. Mary’s (Cabo de Santa Maria), There 
are several channels leading to it, but only one (facing the east) navigable 
for vessels drawing 8 to 12 feet water. 
At low water most of the channels are 
over a succession of sand-banks. 
nearly dry: bottom mud, with abundance of Zostera. 
This is only accessible at high tide
