I'm going to be in an all night race and expect to be sailing back in the
direction of other boats coming right at me.

I thought a night vision scope would be handy, but someone told me only
the
very expensive ones can see half a mile or more. Most can see only about
100
yards which is a short time when two boats are coming at each other on a
collision course.

Anyone have any experience with night vision scopes on the water?

Our only experience with NV gear is that when the skipper of the other boat
is using it, that boat generally falls back rather significantly. Our
suspicion is that the skip is spending too much time being entertained with
the NV gear and not with sailing his boat. We've seen this twice.
