Whenever a vessel enters a small boat harbor, its operator shall immediately come under the jurisdiction of these rules. Such vessels shall be operated, navigated, moored, or stored in accordance with reasonable directions of small boat harbor authorities. The department may designate areas for special boating activities. Each vessel is to be navigated within a state small boat harbor at a speed low enough that its wake will not disturb any other vessel or property.
