Like everything else on the water, " it depends", and that can be minute to minute.

You could have a glass-calm trip out there, take a ball, get ready to go over the side and within minutes be wishing to god you'd never thought of doing it.

It could be glassy calm in Manchioneel and a totaly diffferent story once out of the lee.

Better advice is to check with the dive shop at Cooper and try to arrange a trip with them.

It isn't something I ( or crew I travel with) would plan on doing by dinghy.
