You'd still have to run a wire up the mast, the camera will require power.

You'd have to go with a mechanically stabalized camera... no software can compensate for the movements of a boat.

I think your money would be better spent on a pair of gyro binoculars.

With modern accelerometers going into just about every device imaginable, I'd bet you could do all the image stablization in software. I don't believe that no software could compensate for the movement of a boat. There's a contest in the robotics field in which cameras are mounted to autonomous helicopters, and computers in the helicopters have to navigate a complex course and fly through a window into a building. No boat's motion is as noisy and complex as a four-foot-long gas-powered helicopter.

I have been daydreaming lately about just such a device as well. I have no practical use for such a thing, but it would be cool. Lots of research robots use such cameras for 360 viewing, so it should be easy to get your hands on one. From there, how hard would it be to write a program that does image processing to recognize the presence of other ships, by their lights or hull shape? Especially against the backdrop against an otherwise empty horizon (during the day at least).

Tap into an existing light wire, and run a simple rectifier/diode setup so you can drive one or both depending on polarity. That would be a relatively simple circuit that would cost a couple of dollars, and could easily be encased in epoxy to keep the elements out.

i was just thinking it would be cool to be able to mount a cam on the trailing edge of a keel. idea being to watch prop and rudder.

second thought was, if i have money to do that i should spend it on a bigger boat.

I know what is being proposed is a bit different, but Raymarine does have cameras that can integrate with their latest chartplotters. Night vision to boot. I suspect there is a way to have it talk back to a computer, which may then be transmittable.
