What do you do when your electric toilet stops working? What do you tell your wife and kids to use in a crowded anchorage when your electric toilet stops working?
Come on mate. Get real. If you are in a crowded anchorage you are probably not far from home.
What do you do when your manual toilet cloggs up??
On board you carry a 10 litre paint bucket with a clip lid and a bottle of toilet chemical or a porta potti which are the only things legal to use in protected waters anyway if you do not have a holding tank.
Your lights fail. You have a few torches and a kerosene lamp.
Your radios fail. You carry a hand held VHF and your mobile phone and a signaling mirror.
Your GPS and chartplotter fail. You carry charts, parallel rule, hand bearing compass, dividers and pencils.
Your wife and kids complain. You tell them to put up and shut up because you have more important things to do such as get the vessel safely back home.
If you do not know these basics, you should not be out on the water.
Have you got anything else??
