Petty Officer 2nd Class Peter Dewey, a maritime enforcement specialist from Station Bellingham, Wash., watches as the Royal Canadian Mounted Police patrol boat follows the Coast Guard's 45-foot rescue boat as both services patrol the American-Canadian waters during a shiprider exercise, June 13, 2013. The shiprider agreement allows the Coast Guard to work under Canadian RCMP officers in Canadian waters, while also allowing Canadian RCMP officers to work as customs officers under the Coast Guard.
