Anti-Fouling Invention

Keeps Ships Free From Barnacles

tests of an anti-fouling invention designed for ships’ hulls are being made in Double Bay, N.S.W., and are being closely watched by the Navy, shipping companies, and all small craft owners. The steam yacht Northumbria has been chartered for testing the new invention, and will remain at anchor for about six months.

The hull of the vessel has been scraped, and one side has been painted in strips with various anti-fouling preparations, one section being left clean for the new invention. The system to be tested in volves the continuous pumping of carbon monoxide from the base of the hull, and the gas bubbles up the side of the ship to the surface in a continuous stream.

Tests which have already been made in a small tank have proved singularly successful.

If the tests are successful on the yacht they are likely to have far-reaching effects on ships throughout the world, for shipping companies spend hundreds of thousands of pounds annually in re moving barnacles and marine growth from vessels.
