To GO AROUND
One thing I have to add, is be prepared for loss of horizon/disorientation if you fly any distance over water(ie out of sight of land)in certain weather conditions (a nice flying day on land can be terrible over water, ie calm and hazy, with no/few waves their can be little or no horizon.)If I am stating the obvious please excuse me, but if you haven't experienced it can catch you out!(even when you know about it it can be quite disconcerting!)
Before flying over water, ask yourself how long you would last if immersed at that water temperature and is the risk worth it/required?
