Video Camera to read the water in Bahamas?

I was just poking around Yachtworld to see what B49's are going for these days to see how much I've "lost" already , and then I saw the below picture that just made a light bulb go off in my head. The Raymarine E series can display video from a video feed. Sometimes people use this for engine rooms, underwater views, and stuff like that.

What about mounting a camera at the top of the mast, pointing downward towards the bow so that you get a bird's eye view of the water in front of you. Wouldn't that be an awesome way to navigate the Bahamas? You would have a real-time aerial view of the water right in front of you displayed on your chartplotter right in the cockpit at the helm. What better way to read the water, no? Has anyone done this or otherwise have experience with the concept?

Actually, with a polarizing filter on the lens, it might work fairly well.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

A friend of mine on his vessel, Toucan Dream, did this very thing about ten years ago and for the prupose of viewing the water ahead in the Bahamas. I was never aboard his vessel when navigating in that water, but I got the impression that it was successful.

Could you mount it in such a way to not interfere with anything else up there?

I received a wireless colour video camera from my sister for my birthday. It's meant to be mounted on the rear of a car so you can park in tight spaces or to check for kids in your driveway.

She knows I don't own a car but she also knows I have bitched a bit about docking "blind" from inside the pilothouse as I lose sight of the dock when docking portside. So she cleverly got me this camera.

I'll let you know how it works next year. Mounted high enough, it should be weatherproof, or could be made so. Mounted on a small sealed rotating base, it could see both docks and forward. The polarizing filter is a great idea.

Valiente—

Most small CCD-based cameras will need a circular polarizer rather than a linear one, as a linear one will affect the CCD adversely.

And that little car backup camera has such a wide angle lens that it will probably not be of much use unless close to the subject, ie. mounted on a stanchion.

That's not a problem. Cost to me is zero, remember?

If these don't work, I'm pretty sure I can rig it into a "boatwatch" system that can allow me to look at my boat and the conditions and transmit the image to me elsewhere via stream or still, so it's going to be a useful toy regardless.
