Two agencies, one state, one federal, are looking into a boating incident Saturday that damaged dozens of boats moored in the Bay of Green Bay near Chambers Island. At least one injury has been attributed to the wave action caused by a littoral combat ship apparently involved in a test run. The ship, said to be the USS Milwaukee, generated waves estimated at five feet as it passed about 100 boats. The damage was caused as the vessels were jostled by the wave action. Many of the boaters questioned why Marinette Marine decided to conduct sea trials with the 378 foot ship on such a busy holiday weekend. Initial reports indicate that more than three dozen boats sustained damage. The shipbuilder has been cooperating with investigators from the Department of Natural Resources and the US Coast Guard and indicates that any damage claims will be turned over to its insurance carriers for processing.
