A second shot at water

Water, we all need it!

Since my last post about water I have had some discussions with more experienced sailors on some of the different sailing and cruising forums. I realized that I was thinking about it all wrong.

I was thinking about how much water the two of us would need to survive, not how much we would require. One person asked if I was talking about potable water or water in general.

Although most people agreed on that my plan for the water tanks was inadequate, a select few said that it was very doable. If, one would use the water for cooking and drinking ย only. The luxury of a shower was limited to a cold seawater shower at best. Most of the time wet-wipes were used. Don’t knock the freshening power of a wet-wipe and dishwashing sponge bath on a hot and sticky summer afternoon!

Anyway, I now have realized that a more overlaying plan is needed. And water conservation seems to be on everyone’s lips. Dual taps in the galley, one for freshwater and one for seawater, is almost a requirement rather than a bonus. People shared many conservation ideas, something that can be very important when the water supply is limited.

Power! We can never have enough.

I really hope that everyone out there is using LED lighting by now. The savings in electricity compared to regular filament bulbs are incredible.

But electricity can be a bit complicated. Amps, Amp hours, Watt, Volts and current? What?!
Now what then? It’s a mine field out there. Batteries will show how many Amp hours they have, and products show how many amps they use. Sounds simple right? Well, it is, at least if you know that Amp hours (Ah) are ampere used per hour. So if you had a 83 Ah battery and you have a product using 1 A of current, that product could (theoretically) be run for 83 hours.

It might be easy to just let an electrician deal with that stuff for you, but if you are on a budget or at sea, that might not be an option. You really should have at least a basic understanding of the electronics system on your boat.

The first step on planning your electric system is knowing how much power that you need for the equipment you have and how often you will use this equipment. Make a list of items and how much you will run them. A refrigerator will be turned on 24/7, but an anchorlight will only be turned on for perhaps 12-hour periods, certain days? Ambient lighting will probably only be used for a few hours per day.
