Hi, 1st post, be nice
My wife and I intend to sail across oceans, the biggest risk is falling overboard and not being found. We will have all sorts of locating equipment but if all else fails it is hard to see someone in the water in bad seas, my thinking is it is easy for the person in the water to see the boat so if they had a laser they could shine it at the boat or in the sky? and they should be easy to see.
I have no understanding of the capabilities of lasers so I'm asking....
If it is night and the laser shines straight up will it be visible passing through the air, for how far
If it is day light how far from the person will the light be unmistakably clearly visible if directed towards them
Could it start a fire if it became switched on in a vest by mistake
What power / colour would I need
and the dumbest one for last can I use it underwater to scare off sharks
On the boat - worst case - we are taking turns keeping watch, 3 hours on 3 hours off, someone falls off soon after starting watch by the time the other person comes up on deck the MOB might be a long way away (or 20 feet away), the electronics on the boat allows us to re-trace our route but with currents the MOB may have drifted miles off the original course.
