Nancy and I do a fair amount of traveling in the wee hours getting a head
start on inter island passages. 1-3AM departures are not unusual.
In order to have night vision we get everything ready to leave and then sit
around for another cup of coffee with all the lights out sans the anchor
light. This gives a good bit of increased "night vision". Then after
hoisting the anchor which can be seen with the light from the running lights
we are off.

Keeping the instrument lighting, plotter and radar displays down to a dim
glow and not using flashlights etc really helps to keep that night vision. I
really can't see how the brightness of a FLIR display could possibly improve
the situation. Looking down at it and then out the window would seem to
compromise the good watch lookout/standing that we work hard to maintain.

Our pilothouse is well removed from the saloon but even the valance lighting
turned way down on the dimmer can add bothersome distractions to the
windows.

In reading the reports here on their limited effectiveness I guess we'll
keep that part of the kids inheritance in our pocket but I'm sure we'll find
another way to speed it :-)

As always YMMV..
