The polarising filter sounds like a good idea, if available, to minimise the reflective glare from the sea-surface.
Having experimented (a happy way to while-away a night-time watch; a version of useful moon-gazing), I can confidently say that so long as the observer is aware of the false-horizon effect, and can identify and use the real horizon, the moon can give quite reliable single lines of position, at a time when no other bodies (with horizon) will typically be available.

I have used a polarizing horizon shade on my sextant to mitigate this

horizon shots. It may be something to experiment with, but I would
