I meant his comment about allowing for wave height.  My take on it was
that he thought the small boat guy was better off.  This might be true
in a smooth high sea, if one could be quick enough to get the sight.
Put some chop on top of big rollers and it might be a different story.
I myself have never experienced this, to my regret.
