Should red buoys be passed on your starboard side when going Upstream?

Yes, when going upstream, red buoys should be passed on your starboard side. This follows the IALA (International Association of Lighthouse Authorities) buoyage system, which indicates that red marks are to be kept on your right when navigating upstream. Consequently, green buoys, which are passed on the port side, will be on your left. This system helps ensure safe navigation and consistency on waterways.
