    Ah, 21 ft is a bit low, even for a tanker bridge.  I admit that I didn't do the math, just took my bridge's dip and cut in half, which is closer to the 40 ft mark.

    In any case, a ladened tanker is quite low to the water.  They regularly have waves rolling onto the main deck.  Even on the bulker I was on, our freeboard was only 8-10 feet when we were down to the marks.

    So, given about 20 feet, I expect he was either on the main deck or a deck or two above on the house.  This might also explain the use of a hand compass rather than a repeater.  As to the why, I suspect, and this is pure conjecture, that the vessel may have enclosed bridge wings.  The only other option would be going to the flying bridge, which may be off-limits due to the EMF exposure from the RADAR and SATCOMs.
