Someone has suggested that the protrusion on the bow was indeed an anchor securing point and a similar protrusion can be seen on the old Albatross.
I agree, but of course the Albatross was a much later vessel and made of steel. Bolting on a protrusion would have been straightforward.
Cormorant's bow was more like that of the Gull, made of wood.
So I had another look at the photos I took of Cormorant's bow and there is a substantial metal plate fixed onto the two large stanchions.
I did wonder when I took the photos what the plate was for and perhaps this is how they fixed that anchor extension onto the vessel. There is no sign of the extension now.
