There's hundreds of them but:
Must be waterproof and with steady Red illumination as a lighting option.

The only issue for me is they don't have a red light.
Red light is a help when trying to preserve the deeper levels of dark adaptation. The “Red Light Myth” is an article widely quoted, but in my view it is better bundled with the other crack pot theories trying to disprove well established scientific principles.The 'red light saves your night vision' thing is a myth. It is true that most of the torches don't have a very low light setting, which is what is needed for that reason.

It is a shame, as the best dark adaptation can sometimes be important on a yacht.
I have a few, including a fancy LED Lenser with a seamless adjustable brightness. But my favorite is the cheapest one. It looks exactly like this one. I bought it for a few quid at a Asda camping gear sale (so they made a significant profit it seems).
The battery compartment has a silicone seal and is thus completely waterproof. It uses 3x AAA rechargeable batteries which still had nearly full voltage after our recent night passage, and that was with me reading my book.
The one button cycles through full white, dim white, red and flashing red. The brightness levels are just right for night passage uses: looking at sails or lighting them up with the white and rummaging around the cockpit and everything else with the red - the blinking red is useless, unless you need a backup bicycle tail light. The button is easy to feel and use and the lamp tilts. Headband is comfortable and the whole unit is light enough to not droop down and need a center strap like the much heavier Li-Ion one I have.
Would thoroughly recommend - heck, at that price, get a few spares.
Oh, and I tried both the fancy dimmable white LED and this simple red one, and I agree with Noelex - red is much better for night passage. Details: https://biology.stackexchange.com/questions/2075/does-red-light-preserve-your-night-vision
