Tim Turnbull is retiring from Aquapac, a British maker of waterproof bags and cases, after 22 years as chief executive. Mike Malavasi, the current special accounts director, and John Kelly, the current sales director, will be taking charge of the company. Malavasi's son, Gianluca, will be taking charge of Trunbull's marketing duties. Turnbull was originally hired in 1997, about 14 years into the company's run. He became CEO in 1999. The company was founded in 1983 by a trio of windsurfers who began designing waterproof bags so that they could listen to their Walkmans while out in the surf. The company has since sold more than five million such bags and cases in 60 countries, winning the Queen's Award for Enterprise three times. Aquapac operates out of a factory in the Lambeth district of London. According to the company, 93 percent of its products are made entirely in the U.K.
