Yes, there is a photo for the tool with dimensions that I uploaded. 

Search for "sea chest tools" in Photos on the Amel Yacht Owner's Yahoo website. 

You will find the tool I made that cleans from the top of the sea chest. I used this tool at least 8 times while circumnavigating. A few times for plastic removal, once for jellyfish and the rest for growth. Don't leave port without something to clean this!

The inside of that conduit from the outside of the hull to the ball valve is usually missed during the application of antifouling and, it is perfect for barnacle or mussel growth with the huge flow of water.

I have a '76 Meltem and have recently experienced a blockage below the sea cock feeding the chest. A diver was able to clear about 20cm from the hull surface to where the hose makes a 90 degree bend but was unable to clear further. Any ideas as to clear this last area would be appreciated.
