Thanks All,
Looks like leaving it off is the best option...I will play around with in in kimbe bay before boarding the live aboard and check out any differences.

The image stabilisation features tend to smooth out those fast "trembles", which is not something that happens much underwater because of the damping effect of water. It can't do much for typical underwater "wobbles".
A lot of folks here leave it off. One reason for this is that if a lens was on the borderline of vignetting, having the steadyshot on would sometimes bring the vignetting in and out during a shot. Also I've read that the more extreme stabilisation settings can soften the image (though I find this difficult to believe if it's a mechanical stabilisation system).
Seems strange that your camera doesn't offer you a standard "on" setting for use with no conversion lens. I would say the wide conv. setting is the softer/weaker setting as image stabilisation is less necessary for a wide lens.
If I were you I would set up the camera in the housing at home and try each setting while wobbling the housing around. This is what I did with my Z1 and you can definitely see the difference with this type of test.
I leave my Z1 on standard all the time (as opposed to the other options: hard, soft, or wide conv.).
