You are sailing in iffy visibility and as you came up on deck you notice that your brilliant helmsman is steering toward a buoy that is black, red, black with two black spheres as top marks. What should you do?

Isolated danger buoy. Alter course to starboard. Leave buoy to port. I would also slow down and monitor the depth sounder. With iffy (not restricted) visibility I might also sound 2 short blasts.

While entering a passage at night proceeding in the same direction as the flood current, you see a light flashing (2+1) green every 10 seconds dead ahead. You should:

A) Alter course to starboard
b) Alter course to port
c) Consult chart before altering course to starboard
d) Consult chart before altering course to port
e) either c or d

Our coastal skipper students do night passages. Our coastal navigation students are expected to to know light characteristics. I assume the same is true of ASA / USSailing / RYA.

I will avoid lights for a while.

True / False

It is always safe to pass between red and green buoys.

Don't have my books to check but IIRC that's a bifurcation buoy meaning that there is a split in the channel so you should check your chart and figure out where you're going
