Some days, sun and water conditions make
none of the markers particularly noticeable; however, the NH navigation marking-system has seen a very high years-long endurance for what—eighty-plus years? (
None appear on my 1909 Lake Winnipesaukee chart).
Why, suddenly, can markers not be seen?
Why is greater support seen here for night-time controls on "activity"?
Are we hearing from one of the male population that is colorblind—8%?
Let a woman drive: their colorblindness is only 1% of the population.
Ever notice how easy night navigation is when shoreline lights
are not present?
Artificial light (aboard) can take away one's night vision for many minutes.
When you can't see markers, my advice is to become familiar at slow speeds
in daylight, and especially slow down
at night.
