The Rattler strikes... and propeller-driven ships arrive. more sophisticated designs and machinery and advanced quality lubricants to service them.

Among shipowners and engi- neers Gulf Harmony Oils have an outstanding reputation. They are highest quality rust, oxidation and foam inhibited oils especially for- mulated for use in turbine bearings and gears and for auxiliary ship- board machinery.

The year was 1845. And within the

British Admiralty, the controversy raged on between proponents of the paddle wheel vessel, and those fa- voring the screw propeller.

Suddenly, on an absolutely calm day in the North Sea, in April of that year, the issue was settled.

On that day, the 800-ton Rattler, first screw-driven vessel in the Brit- ish Navy was matched against the 800-ton paddle-driven Alecto. The two vessels were attached, stern-to- stern, and on a given signal their 200 horsepower engines engaged in a "tug-of-war."

The result? The propeller-driven

Rattler towed the Alecto stern first with a speed of 2.8 knots, across the calm North Sea into a new naval age.

Today's propeller-driven ships dwarf the Rattler, and enjoy far

Gulf Harmony Oils-unsurpassed for quality, performance, and excellence.
