By participating in an EPA-funded study of copper-free paints, Hornblower Cruises & Events is pioneering efforts to protect marine life and minimize boating impact in San Diego Bay. Researchers will spend the next two years comparing the effectiveness of ten test paints recently applied to the hull of the San Diego-based M/V Newport Hornblower. "We're doing some experimental painting," said Jim Unger, vice president of Hornblower Cruises and Events. "Traditionally, bottom paint has had toxins – either heavy metals or other biocides – that get into the water system. The Port of San Diego has partnered with Hornblower on the study, which responds to a 1996 San Diego Regional Water Quality Control Board report identifying high levels of dissolved copper in Shelter Island Yacht Basin waters.
