When you see a white buoy with an orange crossed diamond and black lettering what does this marker tell you?

Keep out: A diamond shape with a cross means boats must stay out.

A buoy or sign may show only the symbol or may also indicate Swim Area, Beach, Keep Out, No Boats, Closed Area, Dam, etc.

A white buoy, or other water marker, with orange crossed diamonds indicates area is off-limits to all vessels. These areas could be blocked off for a number of reasons, such as swimming areas, dams, and spillways. If there is a single orange diamond with black lettering, it indicates dangers in the water such as stumps, rocks or dams. Either way, you should definitely avoid those areas.
