Melville Fuller,
Richelieu Navigation Company v…
“ Justice BRADLEY, delivering the opinion of the court, said: 'A lookout is only one of the many precautions which a prudent navigator ought to provide; but it is not indispensable where, from the circumstances of the case, a lookout could not possibly be of any service.' Evidence of a custom to run at full speed in a dense fog, without a lookout, and contrary to the statute, would be clearly inadmissible, and would be of no avail if established. ”
