1. All commercial cargo ships must leave the port, but sports boats may race freely
2. The harbor is closed only to international tourists
3. All sports craft must immediately switch to sailing instead of engine power
4. Navigation is suspended for minor and sports craft; departures (zarpes) are prohibited and all small vessels must remain securely moored or in safe shelter
