From one who's sailed on deep sea vessels for nearly 25 years as a USCG deck officer, many of those years as Master, a word to the ignorant: 1) Vigilance. 2) Speed commensurate with your ability to see-meaning able to stop in 1/2 the visible range. 3) Maintain a Dark wheelhouse-Glass cockpits be damned. 4) Most importantly-Look out the window!! This did not have to happen!! So sad. So stupid. Such a waste.
