In the early 2000s, Austin Sperry, co-founder and president of Metairie, La.-based Maritime Partners LLC, was sailing competitively on the Star Class sailing circuit. It was more than a decade before he would team up with Bick Brooks to start the company that now has a fleet of close to 2,000 inland towboats and barges on long-term charter.
At that time, though, Sperry was pursuing a different dream: the 2004 summer Olympics, and meeting people along the way. “When you race around the country and the world, you form a pretty tight bond with those other competitors,” Sperry said. “It’s like a fraternity.”
Duramax Marine Introduces DuraBlue. A greaseless composite rudder bushing engineered for high performance.
Duramax Marine DuraBlue is a greaseless, pollution-free, self-lubricating rudder bushing designed to outperform traditional bushing materials. DuraBlue proprietary fiber matrix is exceptionally wear resistant, with extremely long wear life, and high load capacity. DuraBlue ultra-low coefficient of friction of 0.1 to 0.2 eliminates stick slip.
There are a many different types of water-lubricated bearings on the market at the moment, mostly based on various woven composites or elastomer-based materials, but Ohio-based Duramax Marine is convinced that nitrile rubber is the best all-round material for this kind of application. “We have over 80 years of experience in producing rubber products and since 1960 we have been producing rubber water-lubricated stern bearings,” said Michael Schonauer, vice president for marketing at Duramax Marine.
