While proceeding downriver (descending) you sight a red diamond-shaped panel with small, red reflector squares in each corner on the left bank. Under the U.S. Aids to Navigation System on the Western Rivers what does this daymark indicate?
⢠Western Rivers aids to navigation and how they differ from coastal IALA-B buoyage ⢠Meaning of red diamond dayboards/panels with red reflectors on the Western Rivers ⢠How crossing vs passing situations are marked for downbound (descending) traffic
⢠Ask yourself: when you are going DOWNRIVER, is the system primarily helping you know where to cross the river or which side to favor? ⢠Think about what a diamond shape usually suggests in navigation marks on rivers: does it normally mark a hazard, a crossing route, or a side to pass on? ⢠Compare how the chart or river pilot books show locations where the channel shifts from one bank to the otherâwhat type of daymark is used there?
⢠Be sure you are thinking specifically about Western Rivers (not general coastal aids or IALA sea buoyage) ⢠Confirm in the Western Rivers system whether red diamond-shaped daymarks are associated with the route of the channel across the river or with special-purpose/hazard information ⢠Doubleâcheck which term (âcrossingâ vs âpassingâ) is used when the channel moves from one side of the river to the other for downbound traffic
