Q

A bluff bar is a bar __________.

🔍 Key Concepts

• River bars and shoals terminology in inland navigation • How a bluff (steep bank) affects current and sediment deposits • The difference between a bar’s shape/position and the way it appears on the surface

💭 Think About

• Think about how current flows past a steep outside bank of a river bend. Where would sand or silt build up, and what kind of underwater shape might that create? • Consider which choice describes a feature that could be especially misleading or hazardous to a pilot who is judging position or depth by eye alone. • Ask yourself: is this term mainly about the bar’s orientation to the current, the bank it comes from, the slope of its sides, or the way it can mislead navigation?

✅ Before You Answer

• Be clear on what "bluff" means in river terminology (steep bank vs. something else). • Separate what describes a physical orientation (direction relative to current or bank) from what describes a navigational hazard or illusion. • Check which option best matches a feature that river pilots specifically note as causing misleading or deceptive indications when conning a vessel.
