can buoy
Cylindrical navigation float
A can buoy is a cylindrical navigational marker floating in water, typically painted green in U.S. waters.
Boaters use can buoys to identify safe channels—they mark the left side of a channel when returning from sea.
The name comes from the shape: a simple cylinder like a tin can.
Keep the can buoy to port as you enter the harbor.
